使用idea2017搭建SSM框架(图文步骤)

使用idea2017搭建SSM框架(图文步骤)

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

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

SELECT * FROM user WHERE id = #{id}

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

Hello World!

onclick test

新建完成后配置项目运行环境，点击Run-Edit Configurations...

点击加号新建运行环境，选择Tomcat Server-Local

选中新建好的服务器，右边选择Deployment,点击加号-Atifact...

选择第二项

然后在右边Application context配置你的项目名

最后运行项目，在打开的页面中点击按钮测试，成功的话会在页面上显示id为1的用户信息
