<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--配置Spring-->
<!--引入Spring的配置文件-->

</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>
3、编写bean-ibatis.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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 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.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
<!--配置数据库的连接池-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="url" value="jdbc:mysql:///lkx"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
</bean>
<!--配置SqlSessionfactorybean这个对象-->

</bean>
<!--配置那个MapperScannerConfigurer-->
<bean id="scannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
<property name="basePackage" value="com.qf.ibatis.mapper"></property>
</bean>
<!--配置aop的自动代理-->
<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
<!--配置包的扫描-->
<context:component-scan base-package="com.qf.ibatis"></context:component-scan>
</beans>
4、编写spring-mvc.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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--使能MVC的注解-->
<mvc:annotation-driven></mvc:annotation-driven>
<!--配置的是SpringMVC的扫描-->
<context:component-scan base-package="com.qf.ibatis.controller"></context:component-scan>
</beans>
5、编写Controller
package com.qf.ibatis.controller;
import com.qf.ibatis.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/** * @Auther: lkx * @Date: 2021/3/10 15:55 * @Description: */
@Controller
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("add")
public String add(){
userService.add();
return "/index.jsp";
}
}
6、编写Service
package com.qf.ibatis.service.impl;
import com.qf.ibatis.mapper.UserMapper;
import com.qf.ibatis.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/** * @Auther: lkx * @Date: 2021/3/10 15:56 * @Description: */
@Service
public class UserService implements IUserService {
@Autowired
private UserMapper userMapper;
@Override
public void add() {
userMapper.add();
}
}
7、编写mapper
public interface UserMapper {
/** * 添加用户 */
void add();
}
8、编写mapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--下面的这个userMapper是可以随便写的 这个的意思是命名空间 只要这个值在这个系统中是唯一的就可以了 你不可以写两个名字一样的nameSpace 一般的写法就是pojo对象Mapper,这样就见名之意了 -->
<mapper namespace="com.qf.ibatis.mapper.UserMapper">
<!--这里就是使用标签来进行方法的描述-->
<insert id="add">
insert into t_user(userName,password) values("lkx","123");
</insert>
</mapper>
