idea 整合SSM(spring spring-mvc mybatis)

1.创建maven-we bapp

接着下一步，填自定义信息，下一步。。。。

2.搭建目录结构

先要让idea识别目录作用，先创建src/main/java和src/test/java目录

选择File-Project Structure，选择modules，然后配置目录，让idea识别。

 

接下来，创建基于mvc目录的结构

 

 

3.配置pom.xml（通过maven仓库管理jar包）

这里时一些常用的配置，如果需要别的，进入http://mvnrepository.com，自己查询需要的。
写好pom之后，注意点击右下角的improt changes

4.配置数据库配置文件

username=root
password=root
jdbcUrl=jdbc\:mysql\:///spring
driverClass=com.mysql.jdbc.Driver

5.配置spring配置文件

6.配置springmvc的配置文件

applicationContext-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context"

   <context:annotation-config/>

　　<!--base-package包扫描，写自己的基础包名-->

   <context:component-scan base-package="cn.tedu"></context:component-scan>
   
</beans>

7.配置sqlMapConfig.xml

<?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>

</configuration>

8.配置web.xml

<?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">

        <filter-name>characterFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

9.代码测试
思路：由外到里一层一层写
创建数据库文件

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',
  `username` varchar(255) NOT NULL COMMENT '用户邮箱',
  `password` varchar(255) NOT NULL COMMENT '用户密码',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
INSERT INTO `user` VALUES ('1', 'smeb', '123123');

创建User类

package cn.tedu.pojo;

public class User {
    private Integer id;
    private String username;
    private String password;

    public Integer getId() {
        return id;
    }

    public void setId(Integer 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 [name="+username+",id="+id+",password"+password+"]";
    }
}

UserController

package cn.tedu.controller;

import cn.tedu.pojo.User;
import cn.tedu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;
@Controller

public class UserController {
    @Autowired
    private UserService userService;
    @RequestMapping("/findAll.action")
    public String findAllAction(Model model){
        List<User> users = userService.findAll();
        model.addAttribute("msg",users);
        return "message";
    }
}

创建UserService的接口

package cn.tedu.service;

import cn.tedu.pojo.User;

import java.util.List;

public interface UserService {
   public List<User> findAll();

}

创建UserServiceImp类

package cn.tedu.service;

import cn.tedu.mapper.UserMapper;
import cn.tedu.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class UserServiceImp implements UserService {
    @Autowired
    private UserMapper userMapper;
    public List<User> findAll() {
        return userMapper.findAll();
    }
}

创建UserMapper接口

package cn.tedu.mapper;

import cn.tedu.pojo.User;

import java.util.List;

public interface UserMapper {
    public List<User> findAll();
}

此时该接口的findAll对应UserMapper里面查询语句的id。

创建UserMapper.xml接口

<?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.tedu.mapper.UserMapper">

   <select id="findAll" resultType="cn.tedu.pojo.User">select * from user</select>
   
</mapper>

创建message.jsp

<%@ page contentType="text/html;charset=UTF-8" isELIgnored="false" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
        users = ${msg}
</body>
</html>

最后配置tomcat-maven-plugin插件，使用该插件来启动项目(pom.xml已经配置)

点击这个，配置tomcat插件

配置好之后，点击run就可以了。


最后打开浏览器输入：http://localhost:8088/findAll.action


读取到数据库的内容，ssm整合完毕！！！
