该仓库提供spring、spring-boot、spirng-cloud 的常用samples。每个用例都提供详细的注释和搭建说明（详见每个sample项目根目录README.md），旨在总结自己工作和学习的结果，也为广大的Java学习和爱好者提供参考。另外因为samples 并不能涵盖该知识点的所有内容，所以每个sample我都会附上本部分内容官方文档的链接作为参考。

# spring +druid+ mybatis（注解配置方式）
|
||||
|
||||
1、创建标准web maven工程，导入依赖
|
||||
|
||||
```xml

</dependency>
|
||||
</dependencies>
|
||||
|
||||
</project>
|
||||
```
|
||||
|
||||
2、新建 DispatcherServletInitializer.java继承自AbstractAnnotationConfigDispatcherServletInitializer,等价于我们在web.xml中配置的前端控制器
|
||||
|
||||
```java
|
||||
public class DispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
|
||||
|
||||
protected Class<?>[] getRootConfigClasses() {
|
||||
return new Class[0];
|
||||
}
|
||||
|
||||
protected Class<?>[] getServletConfigClasses() {
|
||||
return new Class[]{ServletConfig.class};
|
||||
}
|
||||
|
||||
protected String[] getServletMappings() {
|
||||
return new String[]{"/"};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3、基础servlet 3.0的支持，可以采用注解的方式注册druid的servlet和filter
|
||||
|
||||
注：关于servlet 注解支持可以查看[Servlet 规范文档](https://github.com/heibaiying/spring-samples-for-all/blob/master/referenced%20documents/Servlet3.1%E8%A7%84%E8%8C%83%EF%BC%88%E6%9C%80%E7%BB%88%E7%89%88%EF%BC%89.pdf)中**8.1小节 注解和可插拔性**
|
||||
|
||||
```java
|
||||
package com.heibaiying.config.druid;
|
||||
|
||||
import com.alibaba.druid.support.http.StatViewServlet;
|
||||
|
||||
import javax.servlet.annotation.WebInitParam;
|
||||
import javax.servlet.annotation.WebServlet;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description : 配置监控页面用户名密码
|
||||
*/
|
||||
@WebServlet(urlPatterns = "/druid/*",
|
||||
initParams={
|
||||
@WebInitParam(name="resetEnable",value="true"),
|
||||
@WebInitParam(name="loginUsername",value="druid"),
|
||||
@WebInitParam(name="loginPassword",value="druid")
|
||||
})
|
||||
public class DruidStatViewServlet extends StatViewServlet {
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```java
|
||||
package com.heibaiying.config.druid;
|
||||
|
||||
import com.alibaba.druid.support.http.WebStatFilter;
|
||||
|
||||
import javax.servlet.annotation.WebFilter;
|
||||
import javax.servlet.annotation.WebInitParam;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description : WebStatFilter用于采集web-jdbc关联监控的数据
|
||||
*/
|
||||
@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
|
||||
initParams={
|
||||
@WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
|
||||
}
|
||||
)
|
||||
public class DruidStatFilter extends WebStatFilter {
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
4、在resources文件夹下新建数据库配置文件mysql.properties、oracle.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
mysql.driverClassName=com.mysql.jdbc.Driver
|
||||
mysql.url=jdbc:mysql://localhost:3306/mysql
|
||||
mysql.username=root
|
||||
mysql.password=root
|
||||
```
|
||||
|
||||
```properties
|
||||
# oracle 数据库配置
|
||||
oracle.driverClassName=oracle.jdbc.driver.OracleDriver
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
5、在新建数据库配置映射类DataSourceConfig.java
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import lombok.Data;
|
||||
import org.springframework.beans.factory.annotation.Value;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.context.annotation.PropertySource;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :
|
||||
*/
|
||||
|
||||
@Configuration
|
||||
@PropertySource(value = "classpath:mysql.properties")
|
||||
@Data
|
||||
public class DataSourceConfig {
|
||||
|
||||
@Value("${mysql.driverClassName}")
|
||||
private String driverClassName;
|
||||
@Value("${mysql.url}")
|
||||
private String url;
|
||||
@Value("${mysql.username}")
|
||||
private String username;
|
||||
@Value("${mysql.password}")
|
||||
private String password;
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
6、新建ServletConfig.java，进行数据库相关配置
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import com.alibaba.druid.pool.DruidDataSource;
|
||||
import org.mybatis.spring.SqlSessionFactoryBean;
|
||||
import org.mybatis.spring.mapper.MapperScannerConfigurer;
|
||||
import org.springframework.context.annotation.Bean;
|
||||
import org.springframework.context.annotation.ComponentScan;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
|
||||
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
|
||||
import org.springframework.transaction.annotation.EnableTransactionManagement;
|
||||
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
|
||||
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
|
||||
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
|
||||
|
||||
import java.io.IOException;
|
||||
import java.sql.SQLException;
|
||||
|
||||
;
|
||||
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
*/
|
||||
@Configuration
|
||||
@EnableTransactionManagement // 开启声明式事务处理 等价于xml中<tx:annotation-driven/>
|
||||
@EnableWebMvc
|
||||
@ComponentScan(basePackages = {"com.heibaiying.*"})
|
||||
public class ServletConfig implements WebMvcConfigurer {
|
||||
|
||||
/**
|
||||
* 配置静态资源处理器
|
||||
*/
|
||||
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
|
||||
configurer.enable();
|
||||
}
|
||||
|
||||
/**
|
||||
* 配置druid 数据源
|
||||
*/
|
||||
@Bean
|
||||
public DruidDataSource dataSource(DataSourceConfig sourceConfig) throws SQLException {
|
||||
DruidDataSource dataSource = new DruidDataSource();
|
||||
dataSource.setUrl(sourceConfig.getUrl());
|
||||
dataSource.setUsername(sourceConfig.getUsername());
|
||||
dataSource.setPassword(sourceConfig.getPassword());
|
||||
|
||||
// 配置获取连接等待超时的时间
|
||||
dataSource.setMaxWait(60000);
|
||||
|
||||
// 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
|
||||
dataSource.setTimeBetweenEvictionRunsMillis(2000);
|
||||
|
||||
// 配置一个连接在池中最小生存的时间，单位是毫秒
|
||||
dataSource.setMinEvictableIdleTimeMillis(600000);
|
||||
dataSource.setMaxEvictableIdleTimeMillis(900000);
|
||||
|
||||
/* validationQuery 用来检测连接是否有效的sql，要求是一个查询语句，常用select 'x'。
|
||||
* 但是在 oracle 数据库下需要写成 select 'x' from dual 不然实例化数据源的时候就会失败,
|
||||
* 这是由于oracle 和 mysql 语法间的差异造成的
|
||||
*/
|
||||
dataSource.setValidationQuery("select 'x'");
|
||||
|
||||
// 建议配置为true，不影响性能，并且保证安全性。申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效。
|
||||
dataSource.setTestWhileIdle(true);
|
||||
// 申请连接时执行validationQuery检测连接是否有效，做了这个配置会降低性能。
|
||||
dataSource.setTestOnBorrow(false);
|
||||
// 归还连接时执行validationQuery检测连接是否有效，做了这个配置会降低性能
|
||||
dataSource.setTestOnReturn(false);
|
||||
|
||||
// 连接池中的minIdle数量以内的连接，空闲时间超过minEvictableIdleTimeMillis，则会执行keepAlive操作。
|
||||
dataSource.setPhyMaxUseCount(100000);
|
||||
|
||||
/*配置监控统计拦截的filters Druid连接池的监控信息主要是通过StatFilter 采集的，
|
||||
采集的信息非常全面，包括SQL执行、并发、慢查、执行时间区间分布等*/
|
||||
dataSource.setFilters("stat");
|
||||
|
||||
return dataSource;
|
||||
}
|
||||
|
||||
|
||||
/**
|
||||
* 配置mybatis 会话工厂
|
||||
*
|
||||
* @param dataSource 这个参数的名称需要保持和上面方法名一致 才能自动注入,因为
|
||||
* 采用@Bean注解生成的bean 默认采用方法名为名称，当然也可以在使用@Bean时指定name属性
|
||||
*/
|
||||
@Bean
|
||||
public SqlSessionFactoryBean sessionFactoryBean(DruidDataSource dataSource) throws IOException {
|
||||
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
|
||||
sessionFactoryBean.setDataSource(dataSource);
|
||||
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
|
||||
sessionFactoryBean.setMapperLocations(resolver.getResources("classpath*:/mappers/**/*.xml"));
|
||||
sessionFactoryBean.setConfigLocation(resolver.getResource("classpath:mybatisConfig.xml"));
|
||||
return sessionFactoryBean;
|
||||
}
|
||||
|
||||
/**
|
||||
* 配置mybatis 会话工厂
|
||||
*/
|
||||
@Bean
|
||||
public MapperScannerConfigurer MapperScannerConfigurer() {
|
||||
MapperScannerConfigurer configurer = new MapperScannerConfigurer();
|
||||
configurer.setSqlSessionFactoryBeanName("sessionFactoryBean");
|
||||
configurer.setBasePackage("com.heibaiying.dao");
|
||||
return configurer;
|
||||
}
|
||||
|
||||
/**
|
||||
* 定义事务管理器
|
||||
*/
|
||||
@Bean
|
||||
public DataSourceTransactionManager transactionManager(DruidDataSource dataSource) {
|
||||
DataSourceTransactionManager manager = new DataSourceTransactionManager();
|
||||
manager.setDataSource(dataSource);
|
||||
return manager;
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
7、新建mybtais 配置文件 更多settings配置项可以参考[官方文档](http://www.mybatis.org/mybatis-3/zh/configuration.html)
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8" ?>
|
||||
<!DOCTYPE configuration
|
||||
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-config.dtd">
|
||||
|
||||
<!-- mybatis 配置文件 -->
|
||||
<configuration>
|
||||
<settings>
|
||||
<!-- 开启驼峰命名 -->
|
||||
<setting name="mapUnderscoreToCamelCase" value="true"/>
|
||||
<!-- 打印查询sql -->
|
||||
<setting name="logImpl" value="STDOUT_LOGGING"/>
|
||||
</settings>
|
||||
|
||||
</configuration>
|
||||
|
||||
<!--更多settings配置项可以参考官方文档: <a href="http://www.mybatis.org/mybatis-3/zh/configuration.html"/>-->
|
||||
|
||||
```
|
||||
|
||||
8、新建查询接口及其对应的mapper文件
|
||||
|
||||
```java
|
||||
public interface MysqlDao {
|
||||
|
||||
List<Relation> get();
|
||||
}
|
||||
```
|
||||
|
||||
```xml
|
||||
<!DOCTYPE mapper
|
||||
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
|

2、在web.xml 进行如下配置
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

|
||||
version="3.1">
|
||||
|
||||
<!--配置spring前端控制器-->
|
||||
<servlet>
|
||||
<servlet-name>springMvc</servlet-name>
|
||||
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
|
||||
<init-param>
|
||||
<param-name>contextConfigLocation</param-name>
|
||||
<param-value>classpath:springApplication.xml</param-value>
|
||||
</init-param>
|
||||

|
||||
|
||||
<servlet-mapping>
|
||||
<servlet-name>springMvc</servlet-name>
|
||||
<url-pattern>/</url-pattern>
|
||||
</servlet-mapping>
|
||||
|
||||
<!-- 配置 Druid 监控信息显示页面 访问地址 <a src="http://localhost:8080/druid/index.html"> -->

</servlet-mapping>
|
||||
|
||||
<!--配置WebStatFilter用于采集web-jdbc关联监控的数据-->
|

|
||||
|
||||
|
||||
</web-app>
|
||||
```
|
||||
|
||||
3、在resources文件夹下新建数据库配置文件jdbc.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
mysql.url=jdbc:mysql://localhost:3306/mysql
|
||||
mysql.username=root
|
||||
mysql.password=root
|
||||
|
||||
# oracle 数据库配置
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在resources文件夹下创建springApplication.xml 配置文件和druid.xml配置文件
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||

|
||||
|
||||
<!-- 开启注解包扫描-->
|
||||
<context:component-scan base-package="com.heibaiying.*"/>
|
||||
|
||||
<!--使用默认的Servlet来响应静态文件 -->
|
||||
<mvc:default-servlet-handler/>
|
||||
|
||||
<!-- 开启注解驱动-->
|
||||
<mvc:annotation-driven/>
|
||||
|
||||
<!--引入druid.xml配置 由于druid 的可配置项比较多，所以可以单独拆分为一个配置文件-->
|
||||
<import resource="druid.xml"/>
|
||||
|
||||
<!--配置 mybatis 会话工厂 -->
|
||||
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource"/>
|
||||
<!--指定mapper文件所在的位置-->
|
||||
<property name="mapperLocations" value="classpath*:/mappers/**/*.xml"/>
|
||||
<property name="configLocation" value="classpath:mybatisConfig.xml"/>
|
||||
</bean>
|
||||
|
||||
<!--扫描注册接口 -->
|
||||
<!--作用:从接口的基础包开始递归搜索，并将它们注册为 MapperFactoryBean(只有至少一种方法的接口才会被注册;, 具体类将被忽略)-->
|
||||
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
|
||||
<!--指定会话工厂 -->
|
||||
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>

<property name="dataSource" ref="dataSource"/>
|
||||
</bean>
|
||||
|
||||
<!-- 开启事务注解@Transactional支持 -->
|
||||
<tx:annotation-driven/>
|
||||
|
||||
|
||||
</beans>
|
||||
```
|
||||
|

<!--配置druid数据源 关于更多的配置项 可以参考官方文档 <a src="https://github.com/alibaba/druid/wiki/DruidDataSource%E9%85%8D%E7%BD%AE%E5%B1%9E%E6%80%A7%E5%88%97%E8%A1%A8" > -->
|
||||
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
|
||||
<!-- 基本属性 url、user、password -->
|
||||
<property name="url" value="${mysql.url}"/>
|
||||
<property name="username" value="${mysql.username}"/>
|
||||
<property name="password" value="${mysql.password}"/>
|
||||
|
||||
<!-- 配置初始化大小、最小、最大连连接数量 -->
|

<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
|
||||
<property name="timeBetweenEvictionRunsMillis" value="2000"/>
|
||||
|
||||
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
|
||||
<property name="minEvictableIdleTimeMillis" value="600000"/>
|
||||
<!-- 配置一个连接在池中最大生存的时间，单位是毫秒 -->
|
||||
<property name="maxEvictableIdleTimeMillis" value="900000"/>
|
||||
|
||||
<!--validationQuery 用来检测连接是否有效的sql，要求是一个查询语句，常用select 'x'。
|
||||
但是在 oracle 数据库下需要写成 select 'x' from dual 不然实例化数据源的时候就会失败,
|
||||
这是由于oracle 和 mysql 语法间的差异造成的-->
|
||||
<property name="validationQuery" value="select 'x'"/>
|
||||
<!--建议配置为true，不影响性能，并且保证安全性。申请连接的时候检测，
|
||||
如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效。-->
|
||||
<property name="testWhileIdle" value="true"/>
|
||||
<!--申请连接时执行validationQuery检测连接是否有效，做了这个配置会降低性能。-->
|
||||
<property name="testOnBorrow" value="false"/>
|
||||
<!--归还连接时执行validationQuery检测连接是否有效，做了这个配置会降低性能。-->
|
||||
<property name="testOnReturn" value="false"/>
|
||||
|
||||
<!--连接池中的minIdle数量以内的连接，空闲时间超过minEvictableIdleTimeMillis，则会执行keepAlive操作。-->
|
||||
<property name="keepAlive" value="true"/>
|
||||
<property name="phyMaxUseCount" value="100000"/>
|
||||
|
||||
<!-- 配置监控统计拦截的filters Druid连接池的监控信息主要是通过StatFilter 采集的，
|
||||
采集的信息非常全面，包括SQL执行、并发、慢查、执行时间区间分布等-->
|
||||
<property name="filters" value="stat"/>
|
||||
</bean>
|
||||
|
||||
|
||||
</beans>
|
||||
```
|
||||
|
||||
5、新建mybtais 配置文件 更多settings配置项可以参考[官方文档](http://www.mybatis.org/mybatis-3/zh/configuration.html)
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8" ?>
|
||||
<!DOCTYPE configuration
|
||||
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-config.dtd">
|
||||
|
||||
<!-- mybatis 配置文件 -->
|
||||
<configuration>
|
||||
<settings>
|
||||
<!-- 开启驼峰命名 -->
|
||||
<setting name="mapUnderscoreToCamelCase" value="true"/>
|
||||
<!-- 打印查询sql -->
|
||||
<setting name="logImpl" value="STDOUT_LOGGING"/>
|
||||
</settings>
|
||||
|
||||
</configuration>
|
||||
|
||||
<!--更多settings配置项可以参考官方文档: <a href="http://www.mybatis.org/mybatis-3/zh/configuration.html"/>-->
|
||||
|
||||
```
|
||||
|
||||
6、新建查询接口及其对应的mapper文件
|
||||
|
||||
```java
|
||||
public interface MysqlDao {
|
||||
|
||||
List<Relation> get();
|
||||
}
|
||||
```
|
||||
|
||||
```xml
|
||||
<!DOCTYPE mapper
|
||||
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
|
||||
|
||||
<mapper namespace="com.heibaiying.dao.MysqlDao">
|
||||
|
||||
<select id="queryById" resultType="com.heibaiying.bean.Relation">
|
||||
SELECT help_keyword_id AS id,name
|
||||
FROM HELP_KEYWORD
|
||||
WHERE HELP_KEYWORD_ID = #{id}
|
||||
</select>
|
||||
|
||||
</mapper>
|
||||
```
|
||||
|
||||
```mysql
|
||||
public interface OracleDao {
|
||||
|
||||
List<Flow> queryById(long id);
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```xml
|
||||
<!DOCTYPE mapper
|
||||
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
|
||||
|
||||
<mapper namespace="com.heibaiying.dao.OracleDao">
|
||||
|
||||
<select id="queryById" resultType="com.heibaiying.bean.Flow">
|
||||
select * from APEX_030200.WWV_FLOW_CALS where ID = #{id}
|
||||
</select>
|
||||
|
||||
</mapper>
|
||||
```
|
||||
|
||||
7.新建测试controller进行测试
|
||||
|
||||
```java
|
||||
package com.heibaiying.controller;
|
||||
|
||||
import com.heibaiying.bean.Relation;
|
||||
import com.heibaiying.dao.MysqlDao;
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.web.bind.annotation.GetMapping;
|
||||
import org.springframework.web.bind.annotation.PathVariable;
|
||||
import org.springframework.web.bind.annotation.RestController;
|
||||
|
||||
import java.util.List;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :

||||
*/
|
||||
|
||||
@RestController
|
||||
public class MysqlController {
|
||||
|
||||
@Autowired
|
||||
private MysqlDao mysqlDao;
|
||||
|
||||
@GetMapping("relation/{id}")
|
||||
public String get(@PathVariable(name = "id") String id) {
|
||||
return mysqlDao.queryById(id).get(0).toString();
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```java
|
||||
package com.heibaiying.controller;
|
||||
|
||||
import com.heibaiying.dao.OracleDao;
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.web.bind.annotation.GetMapping;
|
||||
import org.springframework.web.bind.annotation.PathVariable;
|
||||
import org.springframework.web.bind.annotation.RestController;
|

# spring 整合 jdbc template（注解配置方式）
|
||||
|
||||
1、创建标准web maven工程，导入依赖
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<project xmlns="http://maven.apache.org/POM/4.0.0"

||||
</dependency>
|
||||
</dependencies>
|
||||
|
||||
</project>
|
||||
```
|
||||
|
||||
2、新建 DispatcherServletInitializer.java继承自AbstractAnnotationConfigDispatcherServletInitializer,等价于我们在web.xml中配置的前端控制器
|
||||
|
||||
```java
|
||||
public class DispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
|
||||
|
||||
protected Class<?>[] getRootConfigClasses() {
|
||||
return new Class[0];
|
||||
}
|
||||
|
||||
protected Class<?>[] getServletConfigClasses() {
|
||||
return new Class[]{ServletConfig.class};
|
||||
}
|
||||
|
||||
protected String[] getServletMappings() {
|
||||
return new String[]{"/"};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3、在resources文件夹下新建数据库配置文件mysql.properties、oracle.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
mysql.driverClassName=com.mysql.jdbc.Driver
|
||||
mysql.url=jdbc:mysql://localhost:3306/mysql
|
||||
mysql.username=root
|
||||
mysql.password=root
|
||||
```
|
||||
|
||||
```properties
|
||||
# oracle 数据库配置
|
||||
oracle.driverClassName=oracle.jdbc.driver.OracleDriver
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在新建数据库配置映射类DataSourceConfig.java
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import lombok.Data;
|
||||
import org.springframework.beans.factory.annotation.Value;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.context.annotation.PropertySource;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :
|
||||
*/
|
||||
|
||||
@Configuration
|
||||
@PropertySource(value = "classpath:mysql.properties")
|
||||
@Data
|
||||
public class DataSourceConfig {
|
||||
|
||||
@Value("${mysql.driverClassName}")
|
||||
private String driverClassName;
|
||||
@Value("${mysql.url}")
|
||||
private String url;
|
||||
@Value("${mysql.username}")
|
||||
private String username;
|
||||
@Value("${mysql.password}")
|
||||
private String password;
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
5、新建ServletConfig.java，进行数据库相关配置
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import org.springframework.context.annotation.Bean;
|
||||
import org.springframework.context.annotation.ComponentScan;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.jdbc.core.JdbcTemplate;
|
||||
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
|
||||
import org.springframework.jdbc.datasource.DriverManagerDataSource;
|
||||
import org.springframework.transaction.annotation.EnableTransactionManagement;
|
||||
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
*/
|
||||
@Configuration
|
||||
@EnableTransactionManagement // 开启声明式事务处理 等价于xml中<tx:annotation-driven/>
|
||||
@ComponentScan(basePackages = {"com.heibaiying.*"})
|
||||
public class ServletConfig implements WebMvcConfigurer {
|
||||
|
||||
/**
|
||||
* 配置数据源
|
||||
*/
|
||||
@Bean
|
||||
public DriverManagerDataSource dataSource(DataSourceConfig sourceConfig) {
|
||||
DriverManagerDataSource dataSource = new DriverManagerDataSource();
|
||||
dataSource.setDriverClassName(sourceConfig.getDriverClassName());
|
||||
dataSource.setUrl(sourceConfig.getUrl());
|
||||
dataSource.setUsername(sourceConfig.getUsername());
|
||||
dataSource.setPassword(sourceConfig.getPassword());
|
||||
return dataSource;
|
||||
}
|
||||
|
||||
/**
|
||||
* 配置jdbcTemplate
|
||||
* @param dataSource 这个参数的名称需要保持和上面方法名一致 才能自动注入,因为
|
||||
* 采用@Bean注解生成的bean 默认采用方法名为名称，当然也可以在使用@Bean时指定name属性
|
||||
*/
|
||||
@Bean
|
||||
public JdbcTemplate jdbcTemplate(DriverManagerDataSource dataSource) {
|
||||
JdbcTemplate jdbcTemplate = new JdbcTemplate();
|
||||
jdbcTemplate.setDataSource(dataSource);
|
||||
return jdbcTemplate;
|
||||
}
|
||||
|
||||
/**
|
||||
* 定义事务管理器
|
||||
*/
|
||||
@Bean
|
||||
public DataSourceTransactionManager transactionManager(DriverManagerDataSource dataSource) {
|
||||
DataSourceTransactionManager manager = new DataSourceTransactionManager();
|
||||
manager.setDataSource(dataSource);
|
||||
return manager;
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
6、新建查询接口及其实现类,这里我查询的表是mysql和oracle中的字典表
|
||||
|
||||
```java
|
||||
public interface MysqlDao {
|
||||
|
||||
List<Relation> get();
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
package com.heibaiying.dao;
|
||||
|
||||
import com.heibaiying.bean.Relation;
|
||||
import com.heibaiying.dao.impl.MysqlDao;
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.jdbc.core.JdbcTemplate;
|
||||
import org.springframework.jdbc.core.RowMapper;
|
||||
import org.springframework.stereotype.Repository;
|
||||
|
||||
import java.sql.ResultSet;
|
||||
import java.sql.SQLException;
|
||||
import java.util.List;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :
|
||||
*/
|
||||
|
||||
@Repository
|
||||
public class MysqlDaoImpl implements MysqlDao {
|
||||
|
||||
@Autowired
|
||||
private JdbcTemplate jdbcTemplate;
|
||||
|
||||
/**
|
||||
* 更多JDBC 的使用可以参考官方文档
|
||||
* @see <a href="https://docs.spring.io/spring/docs/5.1.3.RELEASE/spring-framework-reference/data-access.html#jdbc-JdbcTemplate">JdbcTemplate</a>
|
||||
*/
|
||||
public List<Relation> get() {
|
||||
List<Relation> relations = jdbcTemplate.query("select * from help_keyword where help_keyword_id = ? ", new Object[]{691},
|
||||
new RowMapper<Relation>() {
|
||||
public Relation mapRow(ResultSet rs, int rowNum) throws SQLException {
|
||||
Relation relation = new Relation();
|
||||
relation.setId(rs.getString("help_keyword_id"));
|
||||
relation.setName(rs.getString("name"));
|
||||
return relation;
|
||||
}
|
||||
|
||||
});
|
||||
return relations;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```mysql
|
||||
package com.heibaiying.dao.impl;
|
||||
|
||||
import com.heibaiying.bean.Flow;
|
||||
import java.util.List;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :
|
||||
*/
|
||||
public interface OracleDao {
|
||||
|
||||
List<Flow> get();
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```java
|
||||
package com.heibaiying.dao;
|
||||
|
||||
import com.heibaiying.bean.Flow;
|
||||
import com.heibaiying.dao.impl.OracleDao;
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.jdbc.core.JdbcTemplate;
|
||||
import org.springframework.jdbc.core.RowMapper;
|
||||
import org.springframework.stereotype.Repository;
|
||||
|
||||
import java.sql.ResultSet;
|
||||
import java.sql.SQLException;
|
||||
import java.util.List;
|
||||
|
||||
/**

|
||||
|
||||
@Repository
|
||||
public class OracleDaoImpl implements OracleDao {
|
||||
|
||||
@Autowired
|
||||
private JdbcTemplate jdbcTemplate;
|
||||
|
||||
/**
|
||||

|
||||
* @see <a href="https://docs.spring.io/spring/docs/5.1.3.RELEASE/spring-framework-reference/data-access.html#jdbc-JdbcTemplate">JdbcTemplate</a>
|
||||
*/
|
||||
public List<Flow> get() {
|
||||
List<Flow> flows = jdbcTemplate.query("select * from APEX_030200.WWV_FLOW_CALS where ID = ? ", new Object[]{217584603977429772L},
|
||||
new RowMapper<Flow>() {
|
||||
public Flow mapRow(ResultSet rs, int rowNum) throws SQLException {
|
||||
Flow flow = new Flow();
|
||||
flow.setId(rs.getLong("ID"));
|
||||
flow.setFlowId(rs.getLong("FLOW_ID"));
|
||||
flow.setPlugId(rs.getLong("PLUG_ID"));
|
||||
return flow;
|
||||
}
|
||||
|
||||
});
|
||||
return flows;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
7、新建测试类进行测试
|
||||
|
||||
```java
|
||||
package com.heibaiying.dao;
|
||||
|
||||
import com.heibaiying.bean.Relation;

<artifactId>spring-test</artifactId>
|
||||
<version>${spring-base-version}</version>

|
||||
</project>
|
||||
```
|
||||
|
||||
2、在web.xml 进行如下配置
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
|
||||
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
|
||||
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
|
||||
version="3.1">
|
||||
|
||||
<!--配置spring前端控制器-->
|
||||
<servlet>
|
||||
<servlet-name>springMvc</servlet-name>
|
||||
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
|
||||
<init-param>
|
||||
<param-name>contextConfigLocation</param-name>
|
||||
<param-value>classpath:springApplication.xml</param-value>
|
||||
</init-param>
|
||||
<load-on-startup>1</load-on-startup>
|
||||
</servlet>
|
||||
|
||||
<servlet-mapping>
|
||||
<servlet-name>springMvc</servlet-name>
|
||||
<url-pattern>/</url-pattern>
|
||||
</servlet-mapping>
|
||||
|
||||
</web-app>
|
||||
```
|
||||
|
||||
3、在resources文件夹下新建数据库配置文件jdbc.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
mysql.driverClassName=com.mysql.jdbc.Driver
|
||||
mysql.url=jdbc:mysql://localhost:3306/mysql
|
||||
mysql.username=root
|
||||
mysql.password=root
|
||||
|
||||
# oracle 数据库配置
|
||||
oracle.driverClassName=oracle.jdbc.driver.OracleDriver
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在resources文件夹下创建springApplication.xml 配置文件
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<beans xmlns="http://www.springframework.org/schema/beans"
|
||||
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
|
||||
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
|
||||
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
|
||||
|
||||
<!-- 开启注解包扫描-->
|
||||
<context:component-scan base-package="com.heibaiying.*"/>
|
||||
|
||||
<!--指定配置文件的位置-->
|
||||
<context:property-placeholder location="classpath:jdbc.properties"/>
|
||||
|
||||
<!--配置数据源-->
|
||||
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
|
||||
<!--Mysql 配置-->
|
||||
<property name="driverClassName" value="${mysql.driverClassName}"/>
|
||||
<property name="url" value="${mysql.url}"/>
|
||||
<property name="username" value="${mysql.username}"/>
|
||||
<property name="password" value="${mysql.password}"/>
|
||||
<!--Oracle 配置-->
|
||||
<!--<property name="driverClassName" value="${oracle.driverClassName}"/>
|
||||
<property name="url" value="${oracle.url}"/>
|
||||
<property name="username" value="${oracle.username}"/>
|
||||
<property name="password" value="${oracle.password}"/>-->
|
||||
</bean>
|
||||
|
||||
<!--配置 jdbcTemplate -->
|
||||
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
|
||||
<!--引用上面的数据源-->
|
||||
<property name="dataSource" ref="dataSource"/>
|
||||
</bean>
|
||||
|
||||
<!--定义事务管理器-->
|
||||
<bean id="transactionManager"
|
||||
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
|
||||
<property name="dataSource" ref="dataSource"/>
|
||||
</bean>
|
||||
|
||||
<!-- 开启事务注解@Transactional支持 -->
|
||||
<tx:annotation-driven/>
|
||||
|
||||
</beans>
|
||||
```
|
||||
|
||||
5、新建查询接口及其实现类,这里我查询的表是mysql和oracle中的字典表
|
||||
|
||||
```java
|
||||
public interface MysqlDao {
|
||||
|
||||
List<Relation> get();
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
package com.heibaiying.dao;
|
||||
|
||||
import com.heibaiying.bean.Relation;
|
||||
import com.heibaiying.dao.impl.MysqlDao;
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.jdbc.core.JdbcTemplate;
|
||||
import org.springframework.jdbc.core.RowMapper;
|
||||
import org.springframework.stereotype.Repository;
|
||||
|
||||
import java.sql.ResultSet;
|
||||
import java.sql.SQLException;
|
||||
import java.util.List;
|
||||
|
||||
/**
|
||||

|
||||
|
||||
@Repository
|
||||
public class MysqlDaoImpl implements MysqlDao {
|
||||
|
||||
@Autowired
|
||||
private JdbcTemplate jdbcTemplate;
|
||||
|
||||
/**
|
||||

|
||||
* @see <a href="https://docs.spring.io/spring/docs/5.1.3.RELEASE/spring-framework-reference/data-access.html#jdbc-JdbcTemplate">JdbcTemplate</a>
|
||||
*/
|
||||
public List<Relation> get() {
|
||||
List<Relation> relations = jdbcTemplate.query("select * from help_keyword where help_keyword_id = ? ", new Object[]{691},
|
||||
new RowMapper<Relation>() {
|
||||
public Relation mapRow(ResultSet rs, int rowNum) throws SQLException {
|
||||
Relation relation = new Relation();
|
||||
relation.setId(rs.getString("help_keyword_id"));
|
||||
relation.setName(rs.getString("name"));
|
||||
return relation;
|
||||
}
|
||||
|
||||
});
|
||||
return relations;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```mysql
|
||||
package com.heibaiying.dao.impl;
|
||||
|
||||
import com.heibaiying.bean.Flow;
|
||||
import java.util.List;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||

|
||||
public interface OracleDao {
|
||||
|
||||
List<Flow> get();
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
```java

import org.springframework.jdbc.core.RowMapper;
|
||||
import org.springframework.stereotype.Repository;
|
||||
|
||||
import java.sql.ResultSet;
|

|
||||
/**

|
||||
|
||||
@Repository
|
||||
public class OracleDaoImpl implements OracleDao {
|
||||
|
||||
@Autowired
|
||||
private JdbcTemplate jdbcTemplate;
|
||||
|
||||
/**

|
||||
* @see <a href="https://docs.spring.io/spring/docs/5.1.3.RELEASE/spring-framework-reference/data-access.html#jdbc-JdbcTemplate">JdbcTemplate</a>
|
||||
*/
|
||||
public List<Flow> get() {
|
||||
List<Flow> flows = jdbcTemplate.query("select * from APEX_030200.WWV_FLOW_CALS where ID = ? ", new Object[]{217584603977429772L},
|
||||
new RowMapper<Flow>() {
|
||||
public Flow mapRow(ResultSet rs, int rowNum) throws SQLException {
|
||||
Flow flow = new Flow();
|
||||
flow.setId(rs.getLong("ID"));
|
||||
flow.setFlowId(rs.getLong("FLOW_ID"));
|
||||
flow.setPlugId(rs.getLong("PLUG_ID"));
|
||||
return flow;
|
||||
}
|
||||
|
||||
});
|
||||
return flows;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
6.新建测试类进行测试
|
||||
|
||||
```java
|
||||
package com.heibaiying.dao;
|
||||
|
||||
import com.heibaiying.bean.Relation;

|
||||
|
||||
@RunWith(SpringRunner.class)
|
||||
@ContextConfiguration({"classpath:springApplication.xml"})
|
||||
public class MysqlDaoTest {
|
||||
|
||||
@Autowired
|
||||
private MysqlDao mysqlDao;
|
||||
|
||||
@Test
|
||||
public void get() {
|
||||
List<Relation> relations = mysqlDao.get();
|
||||
if (relations != null) {
|
||||
for (Relation relation : relations) {
|
||||
System.out.println(relation.getId() + " " + relation.getName());
|

}
|
||||
}
|

}
|

</dependency>
|
||||
</dependencies>
|
||||
|
||||
</project>
|
||||
```
|
||||
|
||||
2、新建 DispatcherServletInitializer.java继承自AbstractAnnotationConfigDispatcherServletInitializer,等价于我们在web.xml中配置的前端控制器
|
||||
|
||||
```java
|
||||
public class DispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
|
||||
|
||||
protected Class<?>[] getRootConfigClasses() {
|
||||
return new Class[0];
|
||||
}
|
||||
|
||||
protected Class<?>[] getServletConfigClasses() {
|
||||
return new Class[]{ServletConfig.class};
|
||||
}
|
||||
|
||||
protected String[] getServletMappings() {
|
||||
return new String[]{"/"};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3、在resources文件夹下新建数据库配置文件mysql.properties、oracle.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
mysql.driverClassName=com.mysql.jdbc.Driver
|
||||
mysql.url=jdbc:mysql://localhost:3306/mysql
|
||||
mysql.username=root
|
||||
mysql.password=root
|
||||
```
|
||||
|
||||
```properties
|
||||
# oracle 数据库配置
|
||||
oracle.driverClassName=oracle.jdbc.driver.OracleDriver
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在新建数据库配置映射类DataSourceConfig.java
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import lombok.Data;
|
||||
import org.springframework.beans.factory.annotation.Value;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.context.annotation.PropertySource;
|
||||
|
||||
/**
|
||||
* @author : heibaiying
|
||||
* @description :
|
||||
*/
|
||||
|
||||
@Configuration
|
||||
@PropertySource(value = "classpath:mysql.properties")
|
||||
@Data
|
||||
public class DataSourceConfig {
|
||||
|
||||
@Value("${mysql.driverClassName}")
|
||||
private String driverClassName;
|
||||
@Value("${mysql.url}")
|
||||
private String url;
|
||||
@Value("${mysql.username}")
|
||||
private String username;
|
||||
@Value("${mysql.password}")
|
||||
private String password;
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
5、新建ServletConfig.java，进行数据库相关配置
|
||||
|
||||
```java
|
||||
package com.heibaiying.config;
|
||||
|
||||
import org.mybatis.spring.SqlSessionFactoryBean;
|
||||
import org.mybatis.spring.mapper.MapperScannerConfigurer;
|
||||
import org.springframework.context.annotation.Bean;
|
||||
import org.springframework.context.annotation.ComponentScan;
|
||||
import org.springframework.context.annotation.Configuration;;
|
||||
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
|
||||
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
|
||||
import org.springframework.jdbc.datasource.DriverManagerDataSource;
|
||||
import org.springframework.transaction.annotation.EnableTransactionManagement;
|
||||
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
|
||||

5、新建mybtais 配置文件 更多settings配置项可以参考[官方文档](http://www.mybatis.org/mybatis-3/zh/configuration.html)
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8" ?>
|
||||
<!DOCTYPE configuration
|
||||
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-config.dtd">
|

|
||||
|
||||
```
|
||||
|
||||
5、新建查询接口及其对应的mapper文件
|
||||
|
||||
```java
|
||||
public interface MysqlDao {
|
||||
|
||||
List<Relation> get();
|
||||
}
|

|
||||
WHERE HELP_KEYWORD_ID = #{id}
|
||||
</select>
|
||||
|

```
|
||||
|
||||
```mysql
|
||||
public interface OracleDao {
|
||||

```
|
||||
|
||||
6.新建测试类进行测试

|
||||
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
|
||||
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
|
||||
version="3.1">
|
||||
|
||||
<!--配置spring前端控制器-->
|

```
|
||||
|
||||
3、在resources文件夹下新建数据库配置文件jdbc.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||

mysql.password=root
|
||||
|
||||
# oracle 数据库配置
|
||||
oracle.driverClassName=oracle.jdbc.driver.OracleDriver
|
||||
oracle.url=jdbc:oracle:thin:@//IP地址:端口号/数据库实例名
|
||||
oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在resources文件夹下创建springApplication.xml 配置文件
|
||||
