eclipse下SpringMVC+Maven+Mybatis+MySQL項目搭建html

這篇文章主要講解在eclipse環境下SpringMVC+Maven+Mybatis+MySQL的項目搭建過程。java

建立Maven工程。

　　右擊-->New->Othermysql

　　點擊->Manven Porjectweb

　　點擊->勾選快速框架spring

　　輸入項目名，包（Packaging，若是隻是普通的項目，選jar就行了，若是是web項目就選war，這裏是web項目，因此選擇war）sql

　　右擊項目->Properties->Java Build Path->選擇Libraries->點擊選中 JRE System Library->Edit 數據庫

　　選擇默認JRE，注：必須系統安裝了JDK。apache

　　點擊Project Facets 去掉勾選 Dynamic Web Module 再把 Java 改成系統設置版本。 api

　　再打開Project Facets ->勾選 Dynamic Web Module 選擇3.0版本時，下面有個 Further configuration available... ->點擊瀏覽器

，

　　輸入 content directory 地址： src/main/webapp

　　建立好的目錄以下：

配置Spring MVC

添加包的依賴，編輯pom.xml文件添加以下依賴：（由於個人JDK版本是1.8因此Spring 版本必須爲4.0以上）

    <select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
        SELECT * FROM t_user WHERE USER_ID = #{userId}
    </select>
</mapper>

　　進入mysql 數據庫：

/*新建數據庫*/
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;

/*插入測試數據*/
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, '張三', '123456');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, '李四', '123456');

　　編寫java類：

　　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);  
    }  
}

　　　編寫測試類JUnit4進行單元測試：

　　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" })  
//使用標準的JUnit @RunWith註釋來告訴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());
    }  
}

　　選中方法名->右擊->Run As -> 點擊 JUnit Test

　　顯示測試運行成功！

　　控制檯輸出以下：

　　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 頁面：在src/main/webapp/WEB-INF/新建view文件夾

　　再新建index.jsp 頁面：

<%@ 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>
用戶名： ${user.userName}<br>
 密碼：${user.userPassword}<br>
</body>
</html>

運行！
