使用idea2017搭建SSM框架

搭建个SSM框架居然花费了我好长时间！特此记录！

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

这里可以控制输出格式和内容，有兴趣的可以自己设置

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

import javax.annotation.Resource;
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();
    }

}

IUserDao

package com.chatRobot.dao;
import com.chatRobot.model.User;
public interface IUserDao {

    User selectUser(long id);

}

User

package com.chatRobot.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(int 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;
    }

}

IUserService

package com.chatRobot.service;
import com.chatRobot.model.User;
public interface IUserService {

    public User selectUser(long 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
    private IUserDao userDao;

    public User selectUser(long userId) {
        return this.userDao.selectUser(userId);
    }

}

UserDao.xml

xml version="1.0" encoding="UTF-8"?>



<mapper namespace="com.chatRobot.dao.IUserDao">

    <select id="selectUser" resultType="User" parameterType="long">
        SELECT * FROM user WHERE id = #{id}
    select>

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
    private IUserDao dao;

    @Test
    public void testSelectUser() throws Exception {
        long id = 1;
        User user = 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


<html>
<head>
    <meta charset="UTF-8">
    <title>testtitle>
head>
<script>
    function selectUser() {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function () {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                document.getElementById("test").innerHTML = xmlhttp.responseText;
            }
        }
        xmlhttp.open("POST", "user/showUser.do", true);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlhttp.send("id=1");
    }
script>
<body>
<p id="test">Hello World!p>
<button type="button" onclick="selectUser()">onclick testbutton>
body>
html>
