eclipse下SpringMVC+Maven+Mybatis+MySQL项目搭建

eclipse下SpringMVC+Maven+Mybatis+MySQL项目搭建

这篇文章主要讲解在eclipse环境下SpringMVC+Maven+Mybatis+MySQL的项目搭建过程。

1. 创建Maven工程。

　　右击-->New->Other

　　点击->Manven Porject

　　点击->勾选快速框架

　　输入项目名，包（Packaging，如果只是普通的项目，选jar就好了，如果是web项目就选war，这里是web项目，所以选择war）

　　右击项目->Properties->Java Build Path->选择Libraries->点击选中 JRE System Library->Edit 

　　选择默认JRE，注：必须系统安装了JDK。

　　点击Project Facets 去掉勾选 Dynamic Web Module 再把 Java 改为系统设置版本。  

　　再打开Project Facets ->勾选 Dynamic Web Module 选择3.0版本时，下面有个 Further configuration available... ->点击

，

　　输入 content directory 地址： src/main/webapp

　　创建好的目录如下：

2. 配置Spring MVC

添加包的依赖，编辑pom.xml文件添加如下依赖：（因为我的JDK版本是1.8所以Spring 版本必须为4.0以上）

 　　进入mysql 数据库：

/*新建数据库*/
CREATE DATABASE IF NOT EXISTS stockmgt DEFAULT CHARSET utf8;

/*新建表*/
COLLATE utf8_general_ci;
CREATE TABLE `t_user` (
  `USER_ID` INT(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` CHAR(30) NOT NULL,
  `USER_PASSWORD` CHAR(10) NOT NULL,
  PRIMARY KEY (`USER_ID`),
  KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=INNODB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;

/*插入测试数据*/
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, '张三', '123456');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, '李四', '123456');

　　编写java类：

　　

　　User.java

package com.liaoze.stockmgt.model;

public class User {
    
    private Integer userId;
    private String userName;
    private String userPassword;

    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserPassword() {
        return userPassword;
    }

    public void setUserPassword(String userPassword) {
        this.userPassword = userPassword;
    }

}

　　UserDao.java

package com.liaoze.stockmgt.dao;

import com.liaoze.stockmgt.model.User;

public interface UserDao {
    /**
     * @param userId
     * @return User
     */
    public User selectUserById(Integer userId);
    
}

　　UserService.java

package com.liaoze.stockmgt.service;

import com.liaoze.stockmgt.model.User;

public interface UserService {
    User selectUserById(Integer userId);  
}

　　UserServiceImpl.java

package com.liaoze.stockmgt.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.liaoze.stockmgt.dao.UserDao;
import com.liaoze.stockmgt.model.User;
import com.liaoze.stockmgt.service.UserService;

@Service  
public class UserServiceImpl implements UserService {

    @Autowired  
    private UserDao userDao;  

    public User selectUserById(Integer userId) {  
        return userDao.selectUserById(userId);  
    }  
}

　　　编写测试类JUnit4进行单元测试：

　　SpringTestCase.java

package com.liaoze.stockmgt.test;

import org.junit.runner.RunWith;  
import org.springframework.test.context.ContextConfiguration;  
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;  
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  

//指定bean注入的配置文件  
@ContextConfiguration(locations = { "classpath:application.xml" })  
//使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner  
@RunWith(SpringJUnit4ClassRunner.class)  
public class SpringTestCase extends AbstractJUnit4SpringContextTests {

}

 　　UserServiceTest.java

package com.liaoze.stockmgt.test.service;

import org.junit.Test;  
import org.springframework.beans.factory.annotation.Autowired;
import com.liaoze.stockmgt.model.User;
import com.liaoze.stockmgt.service.UserService;
import com.liaoze.stockmgt.test.SpringTestCase;  

public class UserServiceTest extends SpringTestCase {

    @Autowired  
    private UserService userService; 

    @Test  
    public void selectUserByIdTest(){  
        User user = userService.selectUserById(1);  
        System.out.println(user.getUserName() + ":" + user.getUserPassword());
    }  
}

 　　选中方法名->右击->Run As -> 点击 JUnit Test

 

　　显示测试运行成功！

　　控制台输出如下：

　　新建Controller:

　　新建UserController.java

package com.liaoze.stockmgt.controller;

import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.liaoze.stockmgt.model.User;
import com.liaoze.stockmgt.service.UserService;

@Controller  
public class UserController {  

    @Resource  
    private UserService userService; 

    @RequestMapping("/")    
    public ModelAndView getIndex(){      
        ModelAndView mav = new ModelAndView("index"); 
        User user = userService.selectUserById(1); 
        mav.addObject("user", user); 
        return mav; 
    }    
}  

　　添加jsp 页面：在src/main/webapp/WEB-INF/新建view文件夹

　　再新建index.jsp 页面：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<h2>Hello World!</h2>
用户名： ${user.userName}<br>
 密码：${user.userPassword}<br>
</body>
</html>

 运行！

　　浏览器输入地址：http://127.0.0.1:8080/stockmgt_maven_project/

　　无乱码！成功！
