## 一、前言
|
||||
|
||||
使用Spring+Mybatis操作Phoenix和操作其他的关系型数据库（如Mysql，Oracle）在配置上是基本相同的，下面会分别给出Spring/Spring Boot 整合步骤，完整代码见本仓库：
|
||||
|
||||
+ [Spring + Mybatis + Phoenix](https://github.com/heibaiying/BigData-Notes/tree/master/code/Phoenix/spring-mybatis-phoenix)
|
||||
+ [SpringBoot + Mybatis + Phoenix](https://github.com/heibaiying/BigData-Notes/tree/master/code/Phoenix/spring-boot-mybatis-phoenix)
|
||||
|
||||
## 二、Spring + Mybatis + Phoenix
|
||||
|
||||
### 2.1 项目结构
|
||||

||||
<div align="center"> <img src="https://github.com/heibaiying/BigData-Notes/blob/master/pictures/spring-mybatis-phoenix.png"/> </div>
|
||||
|
||||
### 2.2 主要依赖
|
||||
|
||||
除了Spring相关依赖外，还需要导入`phoenix-core`和对应的Mybatis依赖包
|
||||
|
||||
```xml
|
||||
<!--mybatis 依赖包-->
|
||||
<dependency>
|
||||
<groupId>org.mybatis</groupId>
|
||||
<artifactId>mybatis-spring</artifactId>
|
||||
<version>1.3.2</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.mybatis</groupId>
|
||||
<artifactId>mybatis</artifactId>
|
||||
<version>3.4.6</version>
|
||||
</dependency>
|
||||
<!--phoenix core-->
|
||||
<dependency>
|
||||
<groupId>org.apache.phoenix</groupId>
|
||||
<artifactId>phoenix-core</artifactId>
|
||||
<version>4.14.0-cdh5.14.2</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
### 2.3 数据库配置文件
|
||||
|
||||
在数据库配置文件 `jdbc.properties` 中配置数据库驱动和zookeeper地址
|
||||
|
||||
```properties
|
||||
# 数据库驱动
|
||||
phoenix.driverClassName=org.apache.phoenix.jdbc.PhoenixDriver
|
||||
# zookeeper地址
|
||||
phoenix.url=jdbc:phoenix:192.168.0.105:2181
|
||||
```
|
||||
|
||||
### 2.4 配置数据源和会话工厂
|
||||
|
||||
```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"

|
||||
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">
|
||||
<!--Phoenix配置-->
|
||||
<property name="driverClassName" value="${phoenix.driverClassName}"/>
|
||||
<property name="url" value="${phoenix.url}"/>
|
||||
</bean>
|
||||
|
||||
<!--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"/>
|
||||
<!-- 指定mybatis接口所在的包 -->
|
||||
<property name="basePackage" value="com.heibaiying.dao"/>
|
||||
</bean>
|
||||
|
||||
</beans>
|
||||
```
|
||||
|
||||
### 2.5 Mybtais参数配置
|
||||
|
||||
新建mybtais配置文件，按照需求配置额外参数， 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>
|
||||
```
|
||||
|
||||
### 2.6 查询接口
|
||||
|
||||
```java
|
||||
public interface PopulationDao {
|
||||
|
||||
List<USPopulation> queryAll();
|
||||
|
||||
void save(USPopulation USPopulation);
|
||||
|
||||
USPopulation queryByStateAndCity(@Param("state") String state, @Param("city") String city);
|
||||
|
||||
void deleteByStateAndCity(@Param("state") String state, @Param("city") String city);
|
||||
}
|
||||
```
|
||||
|
||||
```xml
|
||||
<!DOCTYPE mapper
|
||||
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
|
||||
|
||||
<mapper namespace="com.heibaiying.dao.PopulationDao">
|
||||
|
||||
|
||||
<select id="queryAll" resultType="com.heibaiying.bean.USPopulation">
|
||||
SELECT * FROM us_population
|
||||
</select>
|
||||
|
||||
<insert id="save">
|
||||
UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )
|
||||
</insert>
|
||||
|
||||
<select id="queryByStateAndCity" resultType="com.heibaiying.bean.USPopulation">
|
||||
SELECT * FROM us_population WHERE state=#{state} AND city = #{city}
|
||||
</select>
|
||||
|
||||
<delete id="deleteByStateAndCity">
|
||||
DELETE FROM us_population WHERE state=#{state} AND city = #{city}
|
||||
</delete>
|
||||
|
||||
</mapper>
|
||||
```
|
||||
|
||||
### 2.7 单元测试
|
||||
|
||||
```java
|
||||
@RunWith(SpringRunner.class)
|
||||
@ContextConfiguration({"classpath:springApplication.xml"})
|
||||
public class PopulationDaoTest {
|
||||
|
||||
@Autowired
|
||||
private PopulationDao populationDao;
|
||||
|
||||
@Test
|
||||
public void queryAll() {
|
||||
List<USPopulation> USPopulationList = populationDao.queryAll();
|
||||
if (USPopulationList != null) {
|
||||
for (USPopulation USPopulation : USPopulationList) {
|
||||
System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
@Test
|
||||
public void save() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 66666));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
@Test
|
||||
public void update() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 99999));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
|
||||
@Test
|
||||
public void delete() {
|
||||
populationDao.deleteByStateAndCity("TX", "Dallas");
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 三、SpringBoot + Mybatis + Phoenix
|
||||
|
||||
### 3.1 项目结构
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/BigData-Notes/blob/master/pictures/spring-boot-mybatis-phoenix.png"/> </div>
|
||||
|
||||
### 3.2 主要依赖
|
||||
|
||||
```xml
|
||||
<!--spring 1.5 x 以上版本对应 mybatis 1.3.x (1.3.1)
|
||||
关于更多spring-boot 与 mybatis 的版本对应可以参见 <a href="http://www.mybatis.org/spring-boot-starter/mybatis-spring-boot-autoconfigure/">-->
|
||||
<dependency>
|
||||
<groupId>org.mybatis.spring.boot</groupId>
|
||||
<artifactId>mybatis-spring-boot-starter</artifactId>
|
||||
<version>1.3.2</version>
|
||||
</dependency>
|
||||
<!--phoenix core-->
|
||||
<dependency>
|
||||
<groupId>org.apache.phoenix</groupId>
|
||||
<artifactId>phoenix-core</artifactId>
|
||||
<version>4.14.0-cdh5.14.2</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
```
|
||||
|
||||
spring boot 与 mybatis 版本的对应关系：
|
||||
|
||||
| MyBatis-Spring-Boot-Starter 版本 | MyBatis-Spring 版本 | Spring Boot 版本 |
|
||||
| -------------------------------- | ------------------- | ---------------- |
|
||||
| **1.3.x (1.3.1)** | 1.3 or higher | 1.5 or higher |
|
||||
| **1.2.x (1.2.1)** | 1.3 or higher | 1.4 or higher |
|
||||
| **1.1.x (1.1.1)** | 1.3 or higher | 1.3 or higher |
|
||||
| **1.0.x (1.0.2)** | 1.2 or higher | 1.3 or higher |
|
||||
|
||||
### 3.3 配置数据源
|
||||
|
||||
在application.yml 中配置数据源，spring boot 2.x 版本默认采用Hikari作为数据库连接池，Hikari是目前java平台性能最好的连接池，性能好于druid。
|
||||
|
||||
```yaml
|
||||
spring:
|
||||
datasource:
|
||||
#zookeeper地址
|
||||
url: jdbc:phoenix:192.168.0.105:2181
|
||||
driver-class-name: org.apache.phoenix.jdbc.PhoenixDriver
|
||||
|
||||
# 如果不想配置对数据库连接池做特殊配置的话,以下关于连接池的配置就不是必须的
|
||||
# spring-boot 2.X 默认采用高性能的 Hikari 作为连接池 更多配置可以参考 https://github.com/brettwooldridge/HikariCP#configuration-knobs-baby
|
||||
type: com.zaxxer.hikari.HikariDataSource
|
||||
hikari:
|
||||
# 池中维护的最小空闲连接数
|
||||
minimum-idle: 10
|
||||
# 池中最大连接数，包括闲置和使用中的连接
|
||||
maximum-pool-size: 20
|
||||
# 此属性控制从池返回的连接的默认自动提交行为。默认为true
|
||||
auto-commit: true
|
||||
# 允许最长空闲时间
|
||||
idle-timeout: 30000
|
||||
# 此属性表示连接池的用户定义名称，主要显示在日志记录和JMX管理控制台中，以标识池和池配置。 默认值：自动生成
|
||||
pool-name: custom-hikari
|
||||
#此属性控制池中连接的最长生命周期，值0表示无限生命周期，默认1800000即30分钟
|
||||
max-lifetime: 1800000
|
||||
# 数据库连接超时时间,默认30秒，即30000
|
||||
connection-timeout: 30000
|
||||
# 连接测试sql 这个地方需要根据数据库方言差异而配置 例如 oracle 就应该写成 select 1 from dual
|
||||
connection-test-query: SELECT 1
|
||||
|
||||
# mybatis 相关配置
|
||||
mybatis:
|
||||
configuration:
|
||||
# 是否打印sql语句 调试的时候可以开启
|
||||
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
|
||||
```
|
||||
|
||||
### 3.4 新建查询接口
|
||||
|
||||
上面Spring+Mybatis我们使用了XML的方式来写SQL，为了体现Mybatis支持多种方式，这里使用注解的方式来写SQL。
|
||||
|
||||
```java
|
||||
@Mapper
|
||||
public interface PopulationDao {
|
||||
|
||||
@Select("SELECT * from us_population")
|
||||
List<USPopulation> queryAll();
|
||||
|
||||
@Insert("UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )")
|
||||
void save(USPopulation USPopulation);
|
||||
|
||||
@Select("SELECT * FROM us_population WHERE state=#{state} AND city = #{city}")
|
||||
USPopulation queryByStateAndCity(String state, String city);
|
||||
|
||||
|
||||
@Delete("DELETE FROM us_population WHERE state=#{state} AND city = #{city}")
|
||||
void deleteByStateAndCity(String state, String city);
|
||||
}
|
||||
```
|
||||
|
||||
### 3.5 单元测试
|
||||
|
||||
```java
|
||||
@RunWith(SpringRunner.class)
|
||||
@SpringBootTest
|
||||
public class PopulationTest {
|
||||
|
||||
@Autowired
|
||||
private PopulationDao populationDao;
|
||||
|
||||
@Test
|
||||
public void queryAll() {
|
||||
List<USPopulation> USPopulationList = populationDao.queryAll();
|
||||
if (USPopulationList != null) {
|
||||
for (USPopulation USPopulation : USPopulationList) {
|
||||
System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
@Test
|
||||
public void save() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 66666));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
@Test
|
||||
public void update() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 99999));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
|
||||
@Test
|
||||
public void delete() {
|
||||
populationDao.deleteByStateAndCity("TX", "Dallas");
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
## 附：建表语句
|
||||
|
||||
上面单元测试涉及到的测试表的建表语句如下：
|
||||
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS us_population (
|
||||
state CHAR(2) NOT NULL,
|
||||
city VARCHAR NOT NULL,
|
||||
population BIGINT
|
||||
CONSTRAINT my_pk PRIMARY KEY (state, city));
|
||||
|
||||
-- 测试数据
|
||||
UPSERT INTO us_population VALUES('NY','New York',8143197);
|
||||
UPSERT INTO us_population VALUES('CA','Los Angeles',3844829);
|
||||
UPSERT INTO us_population VALUES('IL','Chicago',2842518);
|
||||
UPSERT INTO us_population VALUES('TX','Houston',2016582);
|
||||
UPSERT INTO us_population VALUES('PA','Philadelphia',1463281);
|
||||
UPSERT INTO us_population VALUES('AZ','Phoenix',1461575);
|
||||
UPSERT INTO us_population VALUES('TX','San Antonio',1256509);
|
||||
UPSERT INTO us_population VALUES('CA','San Diego',1255540);
|
||||
UPSERT INTO us_population VALUES('CA','San Jose',912332);
|
||||
```
|
||||

|
||||
### 2.2 主要依赖
|
||||
|
||||
除了 Spring 相关依赖外，还需要导入 `phoenix-core` 和对应的 Mybatis 依赖包
|
||||

</dependency>
|
||||
```
|
||||
|
||||
### 2.3 数据库配置文件
|
||||
|
||||
在数据库配置文件 `jdbc.properties` 中配置数据库驱动和 zookeeper 地址
|
||||
|
||||
```properties
|
||||
# 数据库驱动

### 2.5 Mybtais参数配置
|
||||
|
||||
新建 mybtais 配置文件，按照需求配置额外参数， 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>
|
||||
```
|
||||
|
||||
### 2.6 查询接口
|
||||
|
||||
```java
|
||||
public interface PopulationDao {
|
||||
|
||||
List<USPopulation> queryAll();
|
||||
|
||||
void save(USPopulation USPopulation);
|
||||
|
||||
USPopulation queryByStateAndCity(@Param("state") String state, @Param("city") String city);
|
||||
|
||||
void deleteByStateAndCity(@Param("state") String state, @Param("city") String city);
|
||||
}
|
||||
```
|
||||
|
||||
```xml
|
||||
<!DOCTYPE mapper
|
||||
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
|
||||
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
|
||||
|
||||
<mapper namespace="com.heibaiying.dao.PopulationDao">
|
||||
|
||||
|
||||
<select id="queryAll" resultType="com.heibaiying.bean.USPopulation">
|
||||
SELECT * FROM us_population
|
||||
</select>
|
||||
|
||||
<insert id="save">
|
||||
UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )
|
||||
</insert>
|
||||
|
||||
<select id="queryByStateAndCity" resultType="com.heibaiying.bean.USPopulation">
|
||||
SELECT * FROM us_population WHERE state=#{state} AND city = #{city}
|
||||
</select>
|
||||
|
||||
<delete id="deleteByStateAndCity">
|
||||
DELETE FROM us_population WHERE state=#{state} AND city = #{city}
|
||||
</delete>
|
||||
|
||||
</mapper>
|
||||
```
|
||||
|
||||
### 2.7 单元测试
|
||||
|
||||
```java
|
||||
@RunWith(SpringRunner.class)
|
||||
@ContextConfiguration({"classpath:springApplication.xml"})
|
||||
public class PopulationDaoTest {
|
||||
|
||||
@Autowired
|
||||
private PopulationDao populationDao;
|
||||
|
||||
@Test
|
||||
public void queryAll() {
|
||||
List<USPopulation> USPopulationList = populationDao.queryAll();
|
||||
if (USPopulationList != null) {
|
||||
for (USPopulation USPopulation : USPopulationList) {
|
||||
System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
@Test
|
||||
public void save() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 66666));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
@Test
|
||||
public void update() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 99999));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
|
||||
@Test
|
||||
public void delete() {
|
||||
populationDao.deleteByStateAndCity("TX", "Dallas");
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 三、SpringBoot + Mybatis + Phoenix
|
||||
|
||||
### 3.1 项目结构
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/BigData-Notes/blob/master/pictures/spring-boot-mybatis-phoenix.png"/> </div>
|
||||
|
||||
### 3.2 主要依赖
|
||||
|
||||
```xml
|
||||
<!--spring 1.5 x 以上版本对应 mybatis 1.3.x (1.3.1)
|
||||
关于更多 spring-boot 与 mybatis 的版本对应可以参见 <a href="http://www.mybatis.org/spring-boot-starter/mybatis-spring-boot-autoconfigure/">-->
|
||||
<dependency>
|
||||
<groupId>org.mybatis.spring.boot</groupId>
|
||||
<artifactId>mybatis-spring-boot-starter</artifactId>
|
||||
<version>1.3.2</version>
|
||||
</dependency>
|
||||
<!--phoenix core-->
|
||||
<dependency>
|
||||
<groupId>org.apache.phoenix</groupId>
|
||||
<artifactId>phoenix-core</artifactId>
|
||||
<version>4.14.0-cdh5.14.2</version>
|
||||
</dependency>
|
||||
<dependency>
|
||||
```
|
||||
|
||||
spring boot 与 mybatis 版本的对应关系：
|
||||
|
||||
| MyBatis-Spring-Boot-Starter 版本 | MyBatis-Spring 版本 | Spring Boot 版本 |
|
||||
| -------------------------------- | ------------------- | ---------------- |
|
||||
| **1.3.x (1.3.1)** | 1.3 or higher | 1.5 or higher |
|
||||
| **1.2.x (1.2.1)** | 1.3 or higher | 1.4 or higher |
|
||||
| **1.1.x (1.1.1)** | 1.3 or higher | 1.3 or higher |
|
||||
| **1.0.x (1.0.2)** | 1.2 or higher | 1.3 or higher |
|
||||
|
||||
### 3.3 配置数据源
|
||||
|
||||
在 application.yml 中配置数据源，spring boot 2.x 版本默认采用 Hikari 作为数据库连接池，Hikari 是目前 java 平台性能最好的连接池，性能好于 druid。
|
||||
|
||||
```yaml
|
||||
spring:
|
||||
datasource:
|
||||
#zookeeper 地址
|
||||
url: jdbc:phoenix:192.168.0.105:2181
|
||||
driver-class-name: org.apache.phoenix.jdbc.PhoenixDriver
|
||||
|
||||
# 如果不想配置对数据库连接池做特殊配置的话,以下关于连接池的配置就不是必须的
|
||||
# spring-boot 2.X 默认采用高性能的 Hikari 作为连接池 更多配置可以参考 https://github.com/brettwooldridge/HikariCP#configuration-knobs-baby
|
||||
type: com.zaxxer.hikari.HikariDataSource
|
||||
hikari:
|
||||
# 池中维护的最小空闲连接数
|
||||
minimum-idle: 10
|
||||
# 池中最大连接数，包括闲置和使用中的连接
|
||||
maximum-pool-size: 20
|
||||
# 此属性控制从池返回的连接的默认自动提交行为。默认为 true
|
||||
auto-commit: true
|
||||
# 允许最长空闲时间
|
||||
idle-timeout: 30000
|
||||
# 此属性表示连接池的用户定义名称，主要显示在日志记录和 JMX 管理控制台中，以标识池和池配置。 默认值：自动生成
|
||||
pool-name: custom-hikari
|
||||
#此属性控制池中连接的最长生命周期，值 0 表示无限生命周期，默认 1800000 即 30 分钟
|
||||
max-lifetime: 1800000
|
||||
# 数据库连接超时时间,默认 30 秒，即 30000
|
||||
connection-timeout: 30000
|
||||
# 连接测试 sql 这个地方需要根据数据库方言差异而配置 例如 oracle 就应该写成 select 1 from dual
|
||||
connection-test-query: SELECT 1
|
||||
|
||||
# mybatis 相关配置
|
||||
mybatis:
|
||||
configuration:
|
||||
# 是否打印 sql 语句 调试的时候可以开启
|
||||
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
|
||||
```
|
||||
|
||||
### 3.4 新建查询接口
|
||||
|
||||
上面 Spring+Mybatis 我们使用了 XML 的方式来写 SQL，为了体现 Mybatis 支持多种方式，这里使用注解的方式来写 SQL。
|
||||
|
||||
```java
|
||||
@Mapper
|
||||
public interface PopulationDao {
|
||||
|
||||
@Select("SELECT * from us_population")
|
||||
List<USPopulation> queryAll();
|
||||
|
||||
@Insert("UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )")
|
||||
void save(USPopulation USPopulation);
|
||||
|
||||
@Select("SELECT * FROM us_population WHERE state=#{state} AND city = #{city}")
|
||||
USPopulation queryByStateAndCity(String state, String city);
|
||||
|
||||
|
||||
@Delete("DELETE FROM us_population WHERE state=#{state} AND city = #{city}")
|
||||
void deleteByStateAndCity(String state, String city);
|
||||
}
|
||||
```
|
||||
|
||||
### 3.5 单元测试
|
||||
|
||||
```java
|
||||
@RunWith(SpringRunner.class)
|
||||
@SpringBootTest
|
||||
public class PopulationTest {
|
||||
|
||||
@Autowired
|
||||
private PopulationDao populationDao;
|
||||
|
||||
@Test
|
||||
public void queryAll() {
|
||||
List<USPopulation> USPopulationList = populationDao.queryAll();
|
||||
if (USPopulationList != null) {
|
||||
for (USPopulation USPopulation : USPopulationList) {
|
||||
System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
@Test
|
||||
public void save() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 66666));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
@Test
|
||||
public void update() {
|
||||
populationDao.save(new USPopulation("TX", "Dallas", 99999));
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
|
||||
@Test
|
||||
public void delete() {
|
||||
populationDao.deleteByStateAndCity("TX", "Dallas");
|
||||
USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
|
||||
System.out.println(usPopulation);
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
## 附：建表语句
|
||||
|
||||
上面单元测试涉及到的测试表的建表语句如下：
|
||||
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS us_population (
|
||||
state CHAR(2) NOT NULL,
|
||||
city VARCHAR NOT NULL,
|
||||
population BIGINT
|
||||
CONSTRAINT my_pk PRIMARY KEY (state, city));
|
||||
|
||||
-- 测试数据
|
||||
UPSERT INTO us_population VALUES('NY','New York',8143197);
|
||||
UPSERT INTO us_population VALUES('CA','Los Angeles',3844829);
|
||||
UPSERT INTO us_population VALUES('IL','Chicago',2842518);
|
||||
UPSERT INTO us_population VALUES('TX','Houston',2016582);
|
||||
UPSERT INTO us_population VALUES('PA','Philadelphia',1463281);
|
||||
UPSERT INTO us_population VALUES('AZ','Phoenix',1461575);
|
||||
UPSERT INTO us_population VALUES('TX','San Antonio',1256509);
|
||||
UPSERT INTO us_population VALUES('CA','San Diego',1255540);
|
||||
UPSERT INTO us_population VALUES('CA','San Jose',912332);
|
||||
```
