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。
- 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：
- 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）

加入配置文件

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！
