本文中搭建了SSM框架，在他的基础上，我做了登录和注册的功能。

需要源码的戳这里–>SSM框架源码

请先重点看下面的这段话，有可能就帮你少走了很多弯路

这里列出我在搭建的时候遇到的问题，方便大家搭建的时候少走弯路；
文章容易出错的地方有，1、本人搭建的时候在pom文件中test没有使用4.12而是看到系统已经有了就没有改，所以导致第一步junit测试的时候出错，如果你也是这个错误就将pom文件中的版本改为4.12及以上；2、如果你提示关于IuserServiceImpl的错误，你可以尝试在你的mapper.xml文件中将工作区间加上(namespace=“你的dao接口的全路径”)，3、注册的时候由于user类中有一个data类型的变量，所以直接在controller中将form表单中的数据加载到User实体中会报400的错误，这个时候需要在user实体中的data类型的字段上加上@DateTimeFormat(pattern=“yyyy-MM-dd HH:mm:ss”)注解，4、如果你在jsp或者html中对css、js、image等静态资源引用失败，推荐你使用在springmvc配置文件中使用mvc:default-servlet-handler/的方式，但是需要spring的版本在3.0.5及以上。暂时遇到的问题有这么多，希望能帮助到你们。

需要准备的环境：

　　idea 2017.1

　　jdk1.8

　　Maven 3.3.9

　　请提前将idea与Maven、jdk配置好，本次项目用的都是比较新的

注：配置完ide红线报错没关系！可以run！

步骤：

一、首先使用idea新建一个Maven webapp项目

　　点击Finish，第一次搭建可能会很慢，甚至可能需要VPN才能搭建成功

二、搭建目录结构

　　我这里列出的是搭建完了之后所有的目录和文件，诸位先把目录文件建起来，然后我在给出文件内容

　　这里的目录建好之后还需要设置一下，让idea识别目录作用，选择File-Project Structure

　　设置完成后ok

三、配置文件内容

pom.xml

到这里基本上环境就搭建完成了，下面开始测试

四、测试

先导入一份数据库测试文件

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', 'xxx', 'xxxxx', 'xxxxx', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1');
SET FOREIGN_KEY_CHECKS=1;

接下来配置类

UserController

package com.chatRobot.controller;

import javax.servlet.http.HttpServletRequest;

import com.chatRobot.model.User;
import com.chatRobot.service.IUserService;
import com.fasterxml.jackson.databind.ObjectMapper;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Controller
@RequestMapping("/user")
public class UserController {

    ObjectMapper mapper </span>= <span style="color: #0000ff">new</span><span style="color: #000000"> ObjectMapper();
    response.getWriter().write(mapper.writeValueAsString(user));
    response.getWriter().close();
}

}

}

}

IUserService

package com.chatRobot.service;

import com.chatRobot.model.User;

public interface IUserService {

</span><span style="color: #0000ff">public</span> User selectUser(<span style="color: #0000ff">long</span><span style="color: #000000"> userId);

}

UserServiceImpl

package com.chatRobot.service.impl;

import com.chatRobot.dao.IUserDao;
import com.chatRobot.model.User;
import com.chatRobot.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service(“userService”)
public class UserServiceImpl implements IUserService {

@Resource
</span><span style="color: #0000ff">private</span><span style="color: #000000"> IUserDao userDao;

</span><span style="color: #0000ff">public</span> User selectUser(<span style="color: #0000ff">long</span><span style="color: #000000"> userId) {
    </span><span style="color: #0000ff">return</span> <span style="color: #0000ff">this</span><span style="color: #000000">.userDao.selectUser(userId);
}

}

UserDao.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">

<!– 设置为IUserDao接口方法提供sql语句配置 –>
<mapper namespace=“com.chatRobot.dao.IUserDao”>

<span style="color: #0000ff">&lt;</span><span style="color: #800000">select </span><span style="color: #ff0000">id</span><span style="color: #0000ff">="selectUser"</span><span style="color: #ff0000"> resultType</span><span style="color: #0000ff">="User"</span><span style="color: #ff0000"> parameterType</span><span style="color: #0000ff">="long"</span><span style="color: #0000ff">&gt;</span><span style="color: #000000">

</span><span style="color: #0000ff">&lt;/</span><span style="color: #800000">select</span><span style="color: #0000ff">&gt;</span>

</mapper>

然后新建个测试类，来测试mybatis

IUserDaoTest

package com.chatRobot.dao;

import com.chatRobot.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
</span><span style="color: #0000ff">private</span><span style="color: #000000"> IUserDao dao;

@Test
</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span> testSelectUser() <span style="color: #0000ff">throws</span><span style="color: #000000"> Exception {
    </span><span style="color: #0000ff">long</span> id = 1<span style="color: #000000">;
    User user </span>=<span style="color: #000000"> dao.selectUser(id);
    System.out.println(user.getUsername());
}

}

运行后结果应该是会在控制台输出id为1的用户名，没成功的话就找BUG去吧...

继续新建个页面来测试springmvc和mybatis

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>test</title>
</head>
<script>
    function selectUser() {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function () {
