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

pom.xml

注意右下角更新pom

      %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
    
  
  
    
  

这里可以控制输出格式和内容，有兴趣的可以自己设置

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
#数据库地址
jdbc.url=jdbc:mysql://xxxxxxxxx:3306/ChatRobot?useUnicode=true&characterEncoding=utf8
#用户名
jdbc.username=xxxx
#密码
jdbc.password=xxxxx
#最大连接数
c3p0.maxPoolSize=30
#最小连接数
c3p0.minPoolSize=10
#关闭连接后不自动commit
c3p0.autoCommitonClose=false
#获取连接超时时间
c3p0.checkoutTimeout=10000
#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2

spring-mybatis.xml

spring-mvc.xml

web.xml

  ChatRobot
  ChatRobot_Alpha_0.0.1

  
  
    encodingFilter
    org.springframework.web.filter.CharacterEncodingFilter
    
      encoding
      UTF-8
    
  
  
    encodingFilter
    /*

      contextConfigLocation
      classpath:spring-*.xml
    
    1
    true
  
  
    SpringMVC
    
    /
  

  
    index.html
  

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
