2.web.xml文件配置前端控制器，过滤器（处理中文乱码）和监听器（监听项目启动）
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--配置spring的监听器,默认只加载WEB-INF文件下的applicationContext.xml配置文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--过滤器,处理中文乱码-->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--配置前端控制器-->
<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:springmvc.xml</param-value>
</init-param>
<!--启动服务器，创建该servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3.创建springmvc.xml文件，进行spring与springmvc的整合配置
<?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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
">
<!--开启注解扫描，只扫描controller中的注解-->
<context:component-scan base-package="com.ssm.controller"></context:component-scan>
<!--配置视图解析器对象-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--配置前缀-->
<property name="prefix" value="/"></property>
<!--配置后缀-->
<property name="suffix" value=".jsp"></property>
</bean>
<!--过滤静态资源-->
<mvc:resources mapping="/css/**" location="/css/"></mvc:resources>
<mvc:resources mapping="/images/**" location="/images/"></mvc:resources>
<mvc:resources mapping="/js/**" location="/js/"></mvc:resources>
<!--开启springmvc注解的支持-->
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
</beans>
4.创建applicationContext.xml文件，进行spring与mybatis的整合配置
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
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/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">
<!--扫描包，只扫描service和dao，controller不需要扫描-->
<context:component-scan base-package="com.ssm.dao,com.ssm.service"></context:component-scan>
<!--spring整合Mybatis框架-->
<!--配置连接池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/zml02"></property>
<property name="user" value="root"></property>
<property name="password" value="root"></property>
</bean>
<!--配置SqlSessionFactory工厂-->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!--自动扫描UserDao.xml配置文件-->
<property name="mapperLocations" value="classpath:com/ssm/dao/*.xml"></property>
</bean>
<!--配置UserDao接口所在的包-->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property>
<property name="basePackage" value="com.ssm.dao"></property>
</bean>
<!--配置spring框架声明式事务管理-->
<!--配置事务管理-->
<bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--配置事务通知-->
<tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="*" isolation="DEFAULT"/>
</tx:attributes>
</tx:advice>
</beans>
5.创建与数据库表对应的实体类，实体类属性与表中对应
package com.ssm.entity;
public class User {
private int id;
private String username;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}
6.创建dao层接口
package com.ssm.dao;
import com.ssm.entity.User;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface UserDao {
//查询所有用户信息
public List<User> findAll();
//保存用户信息
public void save(User user);
}
7.创建dao层的xml文件，用于写sql语句，文件路径与dao接口的路径对应，文件名与dao接口名一样
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPEmapper
PUBLIC"-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.ssm.dao.UserDao">
<!--查询所有-->
<select id="findAll" resultType="com.ssm.entity.User">
select * from user
</select>
<!--保存-->
<insert id="save" parameterType="com.ssm.entity.User">
insert into user(username,password) values(#{username},#{password})
</insert>
</mapper>
8.创建service层，创建service层的接口
package com.ssm.service;
import com.ssm.entity.User;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public interface UserService {
//查询所有用户信息
public List<User> findAll();
//保存用户信息
public void save(User user);
}
9.创建service层的实现类
package com.ssm.service.Impl;
import com.ssm.dao.UserDao;
import com.ssm.entity.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public List<User> findAll() {
System.out.println("业务层：查询所有用户信息");
return userDao.findAll();
}
@Override
public void save(User user) {
System.out.println("业务层：添加用户信息");
userDao.save(user);
}
}
10.创建controller层，创建类
package com.ssm.controller;
import com.ssm.entity.User;
import com.ssm.service.Impl.UserServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/UserController")
public class UserController {
@Autowired
private UserServiceImpl userService;
@RequestMapping("/findAll")
public ModelAndView findAll(){
ModelAndView modelAndView=new ModelAndView();
List<User> list=userService.findAll();
modelAndView.addObject("list",list);
for(User u:list){
System.out.println(u);
}
modelAndView.setViewName("list");
System.out.println("controllrt中的findAll方法");
return modelAndView;
}
@RequestMapping("/save")
public String save(User user){
userService.save(user);
return "list";
}
}
11.编写index.jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<a href="UserController/findAll">跳转</a>
<form action="UserController/save" method="post">
<input type="text" name="username">
<input type="text" name="password">
<input type="submit" >
</form>
</body>
</html>
12.编写list.jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@page isELIgnored="false" %>
<html>
<head>
<title>Title</title>
</head>
<body>
${list}
</body>
</html>
