具体步骤

创建User表（使用SQLyog）

CREATE TABLE `user` (
  `id` int(12) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  `gender` varchar(2) DEFAULT NULL,
  `address` varchar(128) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=25 DEFAULT CHARSET=utf8

创建Maven项目（Webapp）添加依赖

 在创建好Maven项目我们要在右边 刷新一下，让Maven管理文件夹，才可以创建

配置Web.xml

  Archetype Created Web Application

  
    spring-dispatcher
    org.springframework.web.servlet.DispatcherServlet

    
      contextConfigLocation
      classpath:spring/spring-*.xml
    
    
    1
  

  
    spring-dispatcher
    
    /
  

数据库的配置文件db.properties

# 连接数据库的参数
db.driver=com.mysql.jdbc.Driver
db.username=root
db.password=123456
db.url=jdbc:mysql://localhost:3306/spring

Mybatis 配置文件

这里我使用了三层架构这样的配置，在web.xml 中，就加载了三层配置文件

spring-dao层配置文件

spring-service配置文件

spring-web配置文件

创建User实体

package com.kangna.domain;

import java.util.Date;

/********************************
 * @Author: kangna
 * @Date: 2019/10/10 18:30
 * @Version: 1.0
 * @Desc: User entity
 ********************************/
public class User {
    private Integer id;
    private String username;
    private Date birthday;
    private String gender;
    private String address;

    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 Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", birthday=" + birthday +
                ", gender='" + gender + '\'' +
                ", address='" + address + '\'' +
                '}';
    }
}

创建UserDao

package com.kangna.dao;

import com.kangna.domain.User;

import java.util.List;

public interface UserDao {

    List findAll();
}

创建 UserService

package com.kangna.service;

import com.kangna.dao.UserDao;
import com.kangna.domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/********************************
 * @Author: kangna
 * @Date: 2019/10/10 19:39
 * @Version: 1.0
 * @Desc:
 ********************************/
@Service
public class UserService {

    @Autowired
    private UserDao userDao;

    public List findAll() {
        return userDao.findAll();
    }
}

创建UserController

package com.kangna.web.controller;

import com.kangna.domain.User;
import com.kangna.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;

/********************************
 * @Author: kangna
 * @Date: 2019/10/10 19:19
 * @Version: 1.0
 * @Desc:
 ********************************/
@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("list")
    public String list(Model model){
        List list = userService.findAll();
        model.addAttribute("list", list);
        return "list";
    }
}

简单的JSP

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%--导入jstl标签库--%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>


    


用户列表：

        

    

        
用户Id
        
用户名称
        
用户地址
    
    

            
${user.id}
            
${user.username}
            
${user.address}
        
    

Dao层测试

import com.kangna.domain.User;
import com.kangna.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/********************************
 * @Author: kangna
 * @Date: 2019/10/11 21:30
 * @Version: 1.0
 * @Desc:
 ********************************/
@RunWith(SpringJUnit4ClassRunner.class)
// 告诉junit Spring 配置文件的位置
@ContextConfiguration({ "classpath:spring/spring-dao.xml" , "classpath:spring/spring-service.xml"})
public class UserDaoTest {


    @Autowired
    private UserService userService;

    @Test
    public void testFindAll() {
        System.out.print(userService.findAll());
    }
}

启动Tomcat进行  Controller的测试 

至此我们就搭建了一个简单的SSM框架，并且测试可以运行。
