<web-app>
<display-name>Archetype Created Web Application</display-name>
<!-- To configure Spring-->
<!-- introduce Spring Configuration file for -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:bean-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- To configure SpringMVC-->
<servlet>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>
3、 To write 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">
<!-- Configure the connection pool of the database -->
<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>
<!-- To configure SqlSessionfactorybean This object -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>
<!-- Configure that 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>
<!-- To configure aop Automatic proxy -->
<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
<!-- Configure package scanning -->
<context:component-scan base-package="com.qf.ibatis"></context:component-scan>
</beans>
4、 To write 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">
<!-- Can make MVC Annotations -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- The configuration is SpringMVC Scan -->
<context:component-scan base-package="com.qf.ibatis.controller"></context:component-scan>
</beans>
5、 To write 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、 To write 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、 To write mapper
public interface UserMapper {
/** * Add users */
void add();
}
8、 To write 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">
<!-- This one below userMapper It can be written casually This means namespace As long as this value is unique in the system You can't write two names nameSpace The general way of writing is pojo object Mapper, In this way, we can see the meaning of name -->
<mapper namespace="com.qf.ibatis.mapper.UserMapper">
<!-- Here is how to use tags to describe methods -->
<insert id="add">
insert into t_user(userName,password) values("lkx","123");
</insert>
</mapper>
