使用idea2017搭建SSM框架及测试-服务器评测

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

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

<?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”>

<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

<!DOCTYPE html>
<html>
<head>
<meta charset=”UTF-8″>
<title>test</title>
</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 test</button>
</body>
</html>

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
