spring+springMVC+Maven+mysql环境搭建

转载：

http://www.importnew.com/20215.html

首先看一下项目截图：

搭建完毕，访问结果：

mysql数据

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


INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');

Maven搭建

选择maven工程

快速搭建

由于是web项目，maven坐标如下

pom.xml如下

分别加入配置文件，具体的路径，参见截图

接口等java文件，如图

UserDao.java

package com.luo.dao;
 
import com.luo.domain.User;
 
public interface UserDao {
 
    /**
     * @param userId
     * @return User
     */
    public User selectUserById(Integer userId);  
 
}

User.java

package com.luo.domain;
 
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() {

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

UserService.java

package com.luo.service;
 
import com.luo.domain.User;
 
public interface UserService {
    User selectUserById(Integer userId);  
}

UserServiceImpl.java

package com.luo.service;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.luo.dao.UserDao;
import com.luo.domain.User;
 
@Service 
public class UserServiceImpl implements UserService {
 
    @Autowired 
    private UserDao userDao;  
 
    public User selectUserById(Integer userId) {  
        return userDao.selectUserById(userId);  
 
    }  
}

单元测试如图

SpringTestCase.java

package com.luo.baseTest;
 
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.luo.service;
 
import org.junit.Test;  
import org.springframework.beans.factory.annotation.Autowired;  
import com.luo.baseTest.SpringTestCase;  
import com.luo.domain.User;
 
public class UserServiceTest extends SpringTestCase {
 
    @Autowired 
    private UserService userService; 
 
    @Test 
    public void selectUserByIdTest(){  
        User user = userService.selectUserById(2);  
        System.out.println(user.getUserName() + ":" + user.getUserPassword());
    }  
}

运行junit，如图：

转为web项目

接下来打开如下页面。将红框里面的勾去掉，确定（OK）：

然后重新打开刚刚那个页面，把Dynamic web Module勾上，就会看到红框的内容，点击：

然后配置

生成结果

配置springMVC依赖

在pom.xml中添加依赖：

<!-- javaee-api包 注意和项目使用的JDK版本对应 -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>
 
<!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

添加spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- 对模型视图添加前后缀 -->

        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        p:prefix="/WEB-INF/view/" p:suffix=".jsp" />

配置web.xml

        <location>/WEB-INF/errorpage/500.jsp</location>
    </error-page>
</web-app>

添加index.jsp，在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp，内容如下

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
用户名： ${user.userName}
 密码：${user.userPassword}
</body>
</html>

编写UserController.java

package com.luo.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.luo.domain.User;
import com.luo.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;    
    }    
}

最后就可以配置在tomcat中运行啦~！
