[置顶] Spring4+Hibernate4

简介：

1.使用注释的方式获取注册bean

2.基于是spring的aop，不需要hibernate单独使用的SessionFactory，Spring来管理Session的事务管理，需要在使用session的dao上加@Transactional

3.使用此功能来自动扫描注册bean

<!-- <context:annotation-config /> -->
<context:component-scan base-package="com.dao" />

Spring配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

dao层：

package com.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.pojo.User;

@Repository("userDAO")
@Transactional
public class UserDAO {
	
	@Resource
	private SessionFactory sessionFactory;

	public void insert(User user) {
		Session session=sessionFactory.getCurrentSession();
		session.save(user);
	}
}
