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"
|
||||

||||

|
||||
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>
|
||||
## 二、 spring 整合 jdbc template
|
||||
|
||||
<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
|
||||
#### 1、在resources文件夹下新建数据库配置文件jdbc.properties
|
||||
|
||||
```properties
|
||||
# mysql 数据库配置
|
||||
@ -134,7 +48,7 @@ oracle.username=用户名
|
||||
oracle.password=密码
|
||||
```
|
||||
|
||||
4、在resources文件夹下创建springApplication.xml 配置文件
|
||||
#### 2、配置Jdbc数据源并定义事务管理器
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
@ -182,34 +96,9 @@ oracle.password=密码

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
