按照来搭建ssm框架，一步成功，特此记录一下。

本机环境：

• idea2017.3
• jdk1.8
• mysql5.5
• maven3.3.9

步骤：

1. idea新建maven webapp项目

2. 搭建项目结构

按照该目录结构创建好相应的文件

搭建时有两个点需要注意一下（针对idea新手）：

（1）新建的目录用途需要设置一下，否则新建时无class文件的选项

（2）有的文件类型没有配置（如xml）,所以需要在idea中配置一下模板

3. 配置配置文件内容

pom.xml

4. 增加类相关代码

导入数据库测试文件

CREATE TABLE `user` (  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',  `email` varchar(255) NOT NULL COMMENT '用户邮箱',  `password` varchar(255) NOT NULL COMMENT '用户密码',  `username` varchar(255) NOT NULL COMMENT '用户昵称',  `role` varchar(255) NOT NULL COMMENT '用户身份',  `status` int(1) NOT NULL COMMENT '用户状态',  `regTime` datetime NOT NULL COMMENT '注册时间',  `regIp` varchar(255) NOT NULL COMMENT '注册IP',  PRIMARY KEY (`id`),  UNIQUE KEY `email` (`email`) USING BTREE) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;INSERT INTO `user` VALUES ('1', '222@qq.com', '123456', '大明', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1');SET FOREIGN_KEY_CHECKS=1;

com.zang.model.User

package com.zang.model;import java.util.Date;public class User {    private long id;    private String email;    private String password;    private String username;    private String role;    private int status;    private Date regTime;    private String regIp;    public long getId() {        return id;    }    public void setId(long id) {        this.id = id;    }    public String getEmail() {        return email;    }    public void setEmail(String email) {        this.email = email;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getRole() {        return role;    }    public void setRole(String role) {        this.role = role;    }    public int getStatus() {        return status;    }    public void setStatus(int status) {        this.status = status;    }    public Date getRegTime() {        return regTime;    }    public void setRegTime(Date regTime) {        this.regTime = regTime;    }    public String getRegIp() {        return regIp;    }    public void setRegIp(String regIp) {        this.regIp = regIp;    }}

com.zang.controller.UserController

package com.zang.controller;import com.fasterxml.jackson.databind.ObjectMapper;import com.zang.model.User;import com.zang.service.IUserService;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;@Controller@RequestMapping("/user")public class UserController {    @Resource    private IUserService userService;    @RequestMapping("/showUser.do")    public void selectUser(HttpServletRequest request, HttpServletResponse response) throws IOException {        request.setCharacterEncoding("UTF-8");        response.setCharacterEncoding("UTF-8");        long userId = Long.parseLong(request.getParameter("id"));        User user = this.userService.selectUser(userId);        ObjectMapper mapper = new ObjectMapper();        response.getWriter().write(mapper.writeValueAsString(user));        response.getWriter().close();    }}

com.zang.service.IUserService

package com.zang.service;import com.zang.model.User;public interface IUserService {    public User selectUser(long userId);}

com.zang.service.impl.UserServiceImpl

package com.zang.service.impl;import com.zang.dao.IUserDao;import com.zang.model.User;import com.zang.service.IUserService;import org.springframework.stereotype.Service;import javax.annotation.Resource;@Service("userService")public class UserServiceImpl implements IUserService{    @Resource    private IUserDao userDao;    public User selectUser(long userId) {        return this.userDao.selectUser(userId);    }}

com.zang.dao.IUserDao

package com.zang.dao;import com.zang.model.User;public interface IUserDao {    User selectUser(long id);}

mapper/UserDao.xml

     
     
         
              SELECT * FROM user WHERE id = #{id}    
     

5. 测试

新建测试类进行测试

IUserDaoTest

package com.zang.dao;import com.zang.model.User;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;// 加载spring配置文件@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration({
    "classpath:spring-mybatis.xml"})public class IUserDaoTest {    @Autowired    private IUserDao dao;    @Test    public void testSelectUser() throws Exception {        long id = 1;        User user = dao.selectUser(id);        System.out.println(user.getUsername());    }}

test

通过web页面发布到服务器，测试springmvc 和 mybatis

index.html
