spring2.5.6调整hibernate3.3.2_Annotation声明式事务管理-第二节

一、根据第一节项目稍作修改即可，看截图需要修改的地方。???


?
?二、按画红线处依次贴出代码

UserDAOImpl.java

?

package com.iskyshop.dao.impl;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import com.iskyshop.dao.UserDAO;
import com.iskyshop.model.User;
@Component
public class UserDAOImpl implements UserDAO {
	@Resource
	private SessionFactory sessionFactory;
	
	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	@Override
	public void saveUser(User user) {
		// TODO Auto-generated method stub
		Session session = sessionFactory.getCurrentSession();
		session.save(user);
		
//		Session session = sessionFactory.openSession();
//		session.beginTransaction();
//		session.save(user);
//		session.getTransaction().commit();
	}

}

?UserServiceImpl.java

?

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;
	
	public UserDAO getUserDAO() {
		return userDAO;
	}

	public void setUserDAO(UserDAO userDAO) {
		this.userDAO = userDAO;
	}

	@Override
	public void saveUser(User user) {
		// TODO Auto-generated method stub
		userDAO.saveUser(user);
	}

}

?Test.java

package com.iskyshop.test;

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 {
	public static void main(String args[]){
		ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
		//因为动态代理是根据接口来动态生成 如果使用转换 会导致方法的丢失,所以下边这段代码应改为。
		//UserServiceImpl usi = (UserServiceImpl) ctx.getBean("userServiceImpl");
		UserService usi = (UserService) ctx.getBean("userServiceImpl");
		User user = new User();
		user.setUsername("iskyshop");
		user.setPassword("www.iskyshop.com");
		user.setAddTime(new Date());
		usi.saveUser(user);
	}
}
