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);
}
}
