...

1.项目结构

IDEA 整合SSM
我这里用的是Maven中的webapp，需要自己完善项目结构。

2.引入依赖

<dependencies>
    <!-- 单元测试 -->
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>

  </dependencies>

因为我的Mapper映射文件是写在src路径下的，而IDEA默认是不会扫描里面的xml文件，所以我们需要进行配置。在pom文件的build标签下加入

<resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.xml</include>
        </includes>
      </resource>
    </resources>

3.web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
  <display-name>Archetype Created Web Application</display-name>

  <!--启动Spring容器-->
  <!--通过ContextLoaderListener在web app启动的时候，
  获取contextConfigLocation配置文件的文件名applicationContext.xml，
  并进行Spring相关初始化工作-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--配置SpringMVC的前端控制器-->
  <servlet>
    <servlet-name>DispatcherServlet</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>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--字符编码过滤器-->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <!--下面两个参数都是确保编码为utf-8-->
    <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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

4.springmvc.xml文件配置

<?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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <!--扫描Controller层注解-->
    <context:component-scan base-package="cn.yf.controller"/>

    <!--配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--将springmvc不能处理的请求交给tomcat，也就是实现静态资源的放行-->
    <mvc:default-servlet-handler/>
    <!--该标签使我们能够使用更多的springmvc高级功能-->
    <mvc:annotation-driven/>

</beans>

5.数据库相关文件配置

db.properties

mysql.driver = com.mysql.jdbc.Driver
mysql.url = jdbc:mysql://localhost:3306/sms?characterEncoding=UTF-8
mysql.username = root
mysql.password = admin

mybatis-config.xml（只配置了别名）

<?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">
<configuration>
    <typeAliases>
        <package name="cn.yf.pojo"/>
    </typeAliases>
</configuration>

6.Spring配置文件（applicationContext.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:aop="http://www.springframework.org/schema/aop"

    <!--Spring的配置文件，这里主要配置和业务逻辑相关的-->

    <!--扫描Service层注解-->
    <context:component-scan base-package="cn.yf.service.impl"/>

    <!--加载数据库配置文件-->

</beans>

7.后台测试

1.数据库结构
IDEA 整合SSM
2.对应的pojo

package cn.yf.pojo;

public class Admin {

    private int id;
    private String name;
    private String password;

    public Admin() {
    }

    public Admin(String name, String password) {
        this.name = name;
        this.password = password;
    }

    public Admin(int id, String name, String password) {
        this.id = id;
        this.name = name;
        this.password = password;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "Admin{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

3.mapper映射文件以及接口

AdminMapper

package cn.yf.mapper;

import cn.yf.pojo.Admin;

import java.util.List;

public interface AdminMapper {

    public List<Admin> getAllAdmin();

    public Admin getAdminById(int id);

    public boolean addAdmin(Admin admin);

    public boolean updateAdmin(Admin admin);

    public boolean deleteAdminById(int id);

}

AdminMapper.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">
<mapper namespace="cn.yf.mapper.AdminMapper">
    <select id="getAllAdmin" resultType="Admin">
        SELECT * FROM admin
    </select>
    
    <select id="getAdminById" resultType="Admin" parameterType="int">
        SELECT  * FROM admin WHERE id = #{id}
    </select>
    
    <insert id="addAdmin" parameterType="Admin">
        INSERT INTO admin(name,password) VALUES (#{name},#{password})
    </insert>
    
    <delete id="deleteAdminById" parameterType="int">
        DELETE FROM admin where id = #{id}
    </delete>

    <update id="updateAdmin" parameterType="Admin">
        UPDATE admin set name = #{name},password = #{password} where id = #{id}
    </update>
    
</mapper>

4.service层接口以及其实现类
AdminService

package cn.yf.service;

import cn.yf.pojo.Admin;

import java.util.List;

public interface AdminService {

    public List<Admin> getAllAdmin();

    public Admin getAdminById(int id);

    public boolean addAdmin(Admin admin);

    public boolean updateAdmin(Admin admin);

    public boolean deleteAdminById(int id);

}

AdminServiceImpl

package cn.yf.service.impl;

import cn.yf.mapper.AdminMapper;
import cn.yf.pojo.Admin;
import cn.yf.service.AdminService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;

@Service
public class AdminServiceImpl implements AdminService {

    @Autowired
    AdminMapper adminMapper;

    @Override
    public List<Admin> getAllAdmin() {
        List<Admin> adminList = adminMapper.getAllAdmin();
        return adminList;
    }

    @Override
    public Admin getAdminById(int id) {
        Admin admin = adminMapper.getAdminById(id);
        return admin;
    }

    @Override
    public boolean addAdmin(Admin admin) {
        boolean result = adminMapper.addAdmin(admin);
        if(result){
            return true;
        }
        return false;
    }

    @Override
    public boolean updateAdmin(Admin admin) {
        boolean result = adminMapper.updateAdmin(admin);
        if(result){
            return true;
        }
        return false;
    }

    @Override
    public boolean deleteAdminById(int id) {
        boolean result = adminMapper.deleteAdminById(id);
        if(result){
            return true;
        }
        return false;
    }
}

5.测试

package cn.yf.junit;

import cn.yf.pojo.Admin;
import cn.yf.service.impl.AdminServiceImpl;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class testSSM{

    @Resource
    AdminServiceImpl adminServiceImpl;

    @Test
    public void test1(){
        List<Admin> adminList = adminServiceImpl.getAllAdmin();
        System.out.println(adminList);
    }

    @Test
    public void test2(){
        Admin admin = adminServiceImpl.getAdminById(1);
        System.out.println(admin);
    }

    @Test
    public void test3(){
        Admin admin = new Admin("入职","加油");
        boolean result = adminServiceImpl.addAdmin(admin);
        System.out.println(result);
    }

    @Test
    public void test4(){
        Admin admin = new Admin(3,"加油","入职");
        boolean result = adminServiceImpl.updateAdmin(admin);
        System.out.println(result);
    }

    @Test
    public void test5(){
        boolean result = adminServiceImpl.deleteAdminById(4);
        System.out.println(result);
    }

}

运行成功： IDEA 整合SSM

8.SpringMVC测试

Controller

package cn.yf.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloSSM {

    @RequestMapping("/success")
    public String test(){
        return "success";
    }

}

success.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>成功</title>
</head>
<body>
<h1>成功了！</h1>
</body>
</html>
