spring2.5整合jpa
一、spring2.5整合jpa spring2.5+jpa(hibernate实现) spring2.5.6整合jpa spring2.5.6+jpa(hibernate实现)
本demo采用spring2.5.6版本,JPA的实现框架为Hibernate。
jar包来源spring-framework-2.5.6-with-dependencies.zip
hibernate-distribute-3.3.2GA-dist.rar
hibernate-annotations-3.4.0.GA.zip
本项目采用mysql数据库自行添加mysql数据库jar包
二、项目结构及jar包截图
三、根据下图结构依次贴出代码
1.UserDAO
package com.iskyshop.dao; import com.iskyshop.model.User; public interface UserDAO { public void saveUser(User user); }
2.UserDAOImpl
package com.iskyshop.dao.impl; import javax.annotation.Resource; import org.springframework.orm.jpa.JpaTemplate; import org.springframework.stereotype.Component; import com.iskyshop.dao.UserDAO; import com.iskyshop.model.User; @Component public class UserDAOImpl implements UserDAO { @Resource(name = "jt") private JpaTemplate jpaTemplate; public JpaTemplate getJpaTemplate() { return jpaTemplate; } public void setJpaTemplate(JpaTemplate jpaTemplate) { this.jpaTemplate = jpaTemplate; } @SuppressWarnings("unchecked") @Override public void saveUser(User user) { // TODO Auto-generated method stub System.out.println(jpaTemplate + "----User"); this.jpaTemplate.persist(user); } }
3.User
package com.iskyshop.model; import java.util.Date; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name = "iskyshop_user") public class User { @Id @GeneratedValue private Long id; private String username; private String password; private Date addTime; public Date getAddTime() { return addTime; } public void setAddTime(Date addTime) { this.addTime = addTime; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
4.UserService
package com.iskyshop.service; import com.iskyshop.model.User; public interface UserService { public void saveUser(User user); }
5.UserServiceImpl
package com.iskyshop.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.iskyshop.dao.UserDAO; import com.iskyshop.model.User; import com.iskyshop.service.UserService; @Service @Transactional public class UserServiceImpl implements UserService{ @Resource private UserDAO userDAO; @Override public void saveUser(User user) { // TODO Auto-generated method stub userDAO.saveUser(user); } }
6.Test
package com.iskyshop.test; import java.sql.SQLException; import java.util.Date; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.iskyshop.model.User; import com.iskyshop.service.UserService; public class Test { /** * @param ISkyShop java多用户商城(国内首家真正好用的java c2c商城系统) * 采用springmvc+jpa+velocity * 免费下载地址:www.iskyshop.com * @throws SQLException */ public static void main(String[] args) throws SQLException { // TODO Auto-generated method stub ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml"); UserService userService = (UserService) ctx.getBean("userServiceImpl"); User user = new User(); user.setUsername("iskyshop-java多用户商城"); user.setPassword("www.iskyshop.com"); user.setAddTime(new Date()); userService.saveUser(user); } }
