Spring+Jersey+JPA+Hibernate+MySQL实现CRUD操作案例

本文承接我的另一篇博文：Spring+Jersey+Hibernate+MySQL+HTML实现用户信息增删改查案例（附Jersey单元测试），主要更改内容如下：

Spring配置文件applicationContext中原先使用的是Hibernate，现在改为Hibernate对JPA的支持；
增加了C3P0连接池；
修改了Dao操作实现，改为Spring接管的JPA实现。
如果读者想详细查看Spring整合Jersey与前端交互可以点击上述连接。本文主要介绍以上三处修改内容，并且使用Jersey Test测试整合结果正确性。博文最后提供源码下载。至于JPA的介绍也不是本文的重点，若读者有不明白的地方可以查看其它文档。

一、添加pom依赖

因为整个项目构建是基于Maven的，所以在使用JPA和C3P0连接池之前，必须先添加相应的依赖JAR包，具体如下：

		<!-- hibernate对JPA支持 -->
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-entitymanager</artifactId>
			<version>4.3.11.Final</version>
		</dependency>

		<!-- hibernate C3P0连接池包 -->
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-c3p0</artifactId>
			<version>4.3.11.Final</version>
		</dependency>

		<dependency>
			<groupId>com.mchange</groupId>
			<artifactId>c3p0</artifactId>
			<version>0.9.2.1</version>
		</dependency>

		<dependency>
			<groupId>com.mchange</groupId>
			<artifactId>mchange-commons-java</artifactId>
			<version>0.2.3.4</version>
		</dependency>

目前比较成熟的 JPA 框架主要包括 Jboss 的 Hibernate EntityManager、Oracle 捐献给 Eclipse 社区的 EclipseLink、Apache 的 OpenJPA 等，如上所示，本文使用的是Hibernate的JPA支持。

二、修改applicationContext.xml

正如Spring接管Hibernate一样，JAP也可以由Spring接管，只需要在applicationContext.xml文件做相应的配置即可，用户便无需关注诸如事务、安全等非业务逻辑的处理及实现。如下为修改后的Spring配置文件。

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

</beans>

jdbc.properties内容如下：

#MySQL jdbc
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root

#c3p0
jdbc.minPoolSize=5
jdbc.maxPoolSize=20
jdbc.initialPoolSize=15 
jdbc.maxStatements=50
jdbc.maxIdleTime=300
jdbc.idleConnectionTestPeriod=60  
jdbc.acquireIncrement=2

三、修改Dao实现

之前使用Hibernate作为持久层框架时，Spring提供了HibernateTemplate对数据库的CRUD等各种操作的实现。现在我们使用JPA操作时，Spring在配置文件中实现了EntityManagerFactory的注入实现，但是并没有提供EntityManager的实现。如果每次都要使用工厂类生成实体管理器，则非常不利于开发。JPA提供了@PersistenceContext注解才解决这个问题。如下：

package com.spring.jersy.jpa.hibernate.dao;

import java.util.ArrayList;
import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;

import org.springframework.stereotype.Repository;

import com.spring.jersy.jpa.hibernate.model.User;

@Repository(value = "userJpaDao")
public class UserJpaDao {

	//通过该注解，在类中便无需EntityManagerFactory创建EntityManager了。
	@PersistenceContext
	private EntityManager entityManager;

	// 根据用户名和密码查询
	public List<User> findByNameAndPassword(User user) {
		
		//如果sql语句中 select 有部分字段或者全部字段，返回的都是对象数组
		String jql = "select u " +
				" from User u where u.username=:username and u.password = :password";
		Query query = entityManager.createQuery(jql);
		query.setParameter("username", user.getUsername());
		query.setParameter("password", user.getPassword());
		@SuppressWarnings("unchecked")
		List<User> listUsers = (List<User>) query.getResultList();
		return listUsers;
	}

	//根据姓名查询
	@SuppressWarnings("unchecked")
	public List<User> findUserByName(String name) {
		List<User> userList = new ArrayList<User>();
		String jql = "from User u where u.username like:name";
		Query query = entityManager.createQuery(jql);
		query.setParameter("name", name);
		userList = (List<User>) query.getSingleResult();
		return userList;
	}

	//添加用户
	public boolean addUser(User user) {
		try {
			entityManager.persist(user);
		} catch (Exception e) {
			return false;
		}
		return true;
	}

	//删除用户
	public boolean deleteUser(Integer id) {
		try {
			User user = entityManager.find(User.class, id);
			if(user != null){
				entityManager.remove(user);
				return true;
			}else {
				return false;
			}
			
		} catch (Exception e) {
			return false;
		}
	}

	//修改用户
	public boolean updateUser(User user){
		try {
		
			String jql = "update User u set u.username = :name, u.password = :pwd, " +
					"u.address = :address, u.tel =:tel where u.id = :id";
			Query query = entityManager.createQuery(jql);
			query.setParameter("name", user.getUsername())
			     .setParameter("pwd", user.getPassword())
			     .setParameter("address", user.getAddress())
			     .setParameter("tel", user.getTel())
			     .setParameter("id", user.getId());
			
		    if(query.executeUpdate() == 1){
		    	return true;
		    }else {
		    	return false;
		    }
			
		} catch (Exception e) {
			return false;
		}
	}
}

四、业务层实现

业务层实现不需要太多修改，只需引用JPA Dao实现即可。具体如下：

package com.spring.jersy.jpa.hibernate.service;

import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.spring.jersy.jpa.hibernate.dao.UserJpaDao;
import com.spring.jersy.jpa.hibernate.model.User;


@Service(value="userService")
public class UserService {

	@Resource(name="userJpaDao")
	private UserJpaDao userJpaDao;
	
	public User findUserByNameAndPassword (User user) {
		List<User> listUsers = userJpaDao.findByNameAndPassword(user);
		
		if(listUsers.size() > 0) {
			return listUsers.get(0);
		}
		return null;
	}
	
	public User findUserByName (String name) {
        List<User> listUsers = userJpaDao.findUserByName(name);
		if(listUsers.size() > 0) {
			return listUsers.get(0);
		}
		return null;
	}
	
	public boolean deleteUser(Integer id) {
		return userJpaDao.deleteUser(id);
	}
	
	public boolean addUser(User user) {
		return userJpaDao.addUser(user);
	}
	
	public boolean updateUser(User user){
		return userJpaDao.updateUser(user);
	}

	public UserJpaDao getUserJpaDao() {
		return userJpaDao;
	}

	public void setUserJpaDao(UserJpaDao userJpaDao) {
		this.userJpaDao = userJpaDao;
	}
}

五、资源类

资源类实现主要是Jersey，本文因为上接Spring+Jersey+Hibernate+MySQL+HTML实现用户信息增删改查案例（附Jersey单元测试）文章，此处Jersey资源类不作任何修改，具体如下：

package com.spring.jersy.hibernate.resource;

import javax.annotation.Resource;
import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import net.sf.json.JSONObject;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import com.spring.jersy.hibernate.model.User;
import com.spring.jersy.hibernate.service.UserService;

/**
 * Spring 使用Component注解Jersey资源类
 * Path：相当于Spring MVC中的RequestMapping，用于HTTP URL请求
 * Scope：表示Spring的单例模式或者原型模式prototype
 */
@Component
@Path("/user")
@Scope("prototype")
public class UserResource {

	@Resource(name = "userService")
	private UserService userService;
	private String message;

	/**
	 * GET：表示Jersey rest查询请求
	 * Path:此处完整路径需接类上面的Path,如：user/exist/xx/1233，才会跳转到该方法处理
	 * Consumes:表示前端请求数据格式
	 * Produces:表示返回值数据格式
	 * PathParam:用于注解参数变量，与URL中对应的变量名对应，达到传递的作用
	 */
	@GET
	@Path("/exist/{username}/{password}")
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	//查询
	public String isExist(@PathParam("username") String username,
			@PathParam("password") String password) {

		User user = new User();
		user.setUsername(username);
		user.setPassword(password);
		User result = userService.findUserByNameAndPassword(user);
		
		/**
		 * Spring+Jersey框架，不会主动帮助我们将传递的对象转换成JSON数据格式，
		 * 需使用JSON lib类中的JSONObject或者JSONArray转换才能够传递，否则前端
		 * 会报302错误。
		 */
		JSONObject jsonUser = JSONObject.fromObject(result);
		return jsonUser.toString();
	}

	@POST
	@Path("/addUser")
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	//添加
	public String addUser(User user) {

		boolean flag = userService.addUser(user);
		if (flag) {
			message = "success";
		} else {
			message = "fail";
		}
		JSONObject jsonObject = new JSONObject();
		jsonObject.put("message", message);
		return jsonObject.toString();
	}

	@DELETE
	@Path("/deleteUser/{id}")
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	//删除
	public String deleteUser(@PathParam("id") Integer id) {

		boolean flag = userService.deleteUser(id);
		if (flag) {
			message = "success";
		} else {
			message = "fail";
		}
		JSONObject jsonObject = new JSONObject();
		jsonObject.put("message", message);
		return jsonObject.toString();
	}

	@PUT
	@Path("/updateUser/{id}")
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	//修改
	public String updateUser(@PathParam("id") Integer id, User user) {
		user.setId(id);
		boolean flag = userService.updateUser(user);
		if (flag) {
			message = "success";
		} else {
			message = "fail";
		}
		JSONObject jsonObject = new JSONObject();
		jsonObject.put("message", message);
		return jsonObject.toString();
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}
}

六、单元测试

此处使用的单元测试是Jersey Test，测试类内容如下：

package com.spring.jersy.hibernate.test;

import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.request.RequestContextListener;
import com.sun.jersey.spi.spring.container.servlet.SpringServlet;
import com.sun.jersey.test.framework.JerseyTest;
import com.sun.jersey.test.framework.WebAppDescriptor;

/**
 * 主要加载web.xml中的配置信息
 * @author Administrator
 *
 */
public abstract class BaseJerseyServiceTest extends JerseyTest {
	    @Override
	    protected WebAppDescriptor configure() {
	        return  new WebAppDescriptor.Builder("com.spring.jersy.jpa.hibernate.resource")
	        .contextParam( "contextConfigLocation", "classpath:com/spring/jersy/hibernate/config/applicationContext.xml")
	        //.servletClass(SpringServlet.class)
	        .filterClass(SpringServlet.class)
	        .initParam("com.sun.jersey.config.feature.Redirect", "true")
	        .initParam("com.sun.jersey.config.feature.FilterForwardOn404", "true")
	        .initParam("com.sun.jersey.config.property.WebPageContentRegex", "/(images|css|jsp)/.*")
	        .initParam("com.sun.jersey.api.json.POJOMappingFeature", "true")
	        .initParam("com.sun.jersey.config.property.packages", "com.spring.jersy.jpa.hibernate.resource")
	        .contextListenerClass(ContextLoaderListener.class)
	        .requestListenerClass(RequestContextListener.class)
	        .build();
	    }
}

package com.spring.jersy.jpa.hibernate.test;


import javax.ws.rs.core.MediaType;
import org.junit.Before;
import org.junit.Test;
import com.spring.jersy.jpa.hibernate.model.User;
import com.sun.jersey.api.client.WebResource;
public class UserResourceTest extends BaseJerseyServiceTest {

	private WebResource webResource;

	@Before
	public void setUp() throws Exception {
		webResource = resource();
		// webResource.accept("application/json");
	}

	@Test
	public void testIsExist() {
		String response = webResource.path("/user/exist/xx/1233").get(
				String.class);
		System.out.println(response);
	}

	@Test
	public void testAddUser() {

		User user = new User();
		user.setUsername("wwwx");
		user.setPassword("pwd");
		user.setAddress("江苏盐城");
		user.setTel("12333");
		String response = webResource.path("/user/addUser")
				.entity(user, "application/json").post(String.class, user);
		System.out.println(response.toString());
	}

	@Test
	public void testDeleteUser() {
		String response = webResource.path("/user/deleteUser/59").delete(
				String.class);
		System.out.println(response.toString());
	}

	@Test
	public void testUpdateUser() {
		User user = new User();
		user.setUsername("王三儿");
		user.setPassword("wangsaner");
		String response = webResource.path("/user/updateUser/64")
				.entity(user, MediaType.APPLICATION_JSON).put(String.class);
		System.out.println(response.toString());
	}
}

七、测试结果如下：

Hibernate: 
    insert 
    into
        test.user
        (username, password, address, tel) 
    values
        (?, ?, ?, ?)
{"message":"success"}

Hibernate: 
    select
        user0_.id as id1_2_0_,
        user0_.username as username2_2_0_,
        user0_.password as password3_2_0_,
        user0_.address as address4_2_0_,
        user0_.tel as tel5_2_0_ 
    from
        test.user user0_ 
    where
        user0_.id=?
{"message":"fail"}

Hibernate: 
    update

附1：异常

将项目部署到服务器上运行，在Web调试过程中，所有调试一切正常，但是在运行单元测试的时候报如下异常错误：

解决办法：具体原因是因为项目中存在其他版本的JPA实现，导致版本冲突，在调用javax.persistence.*时冲突，如Eclipse link，所以需要在pom.xml中去掉Eclipse 对JPA的支持。

		<!-- 增加Eclipse JPA Provider支持 -->
<!-- 		<dependency>
			<groupId>org.eclipse.persistence</groupId>
			<artifactId>org.eclipse.persistence.jpa</artifactId>
			<version>2.6.0</version>
		</dependency>
