spring提供了一個數據訪問層的類：org.springframework.orm.hibernate3.support.HibernateDaoSupport。一般是讓

dao繼承該類，然後在dao中定義個set方法用來初始化HibernateDaoSupport的HibernateTemplate或者是

SessionFactory.

因為 HibernateTemplate和SessionFactory都是fanal類型，因此不能被重寫。此時能夠隨便set一個方法，註入

資源，在set方法裏傳入SessionFactory或者HibernateTemplate,然後再通過super或者this調用HibernateDaoSupport的

相應set方法。

HibernateDao接口：

package com.dao;

public interface HibernateDao {

}

能夠在裏面封裝一些經常用法。

HibernateDaoImpl:

package com.dao;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
@Repository
public class HibernateDaoImpl extends HibernateDaoSupport implements HibernateDao{
	@Resource
	public void setOne(SessionFactory sessionFactory){
		this.setSessionFactory(sessionFactory);
	}
}

有set方法之處。就能夠註入。setOne註入參數sessionFactory,初始化HibernateDaoSupport的SessionFactory.

userDaoImpl:

package com.dao;

import javax.annotation.Resource;

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

import com.entity.Student;
@Repository(value="userDao")
public class UserDaoImpl extends HibernateDaoImpl implements UserDao{	
	
	public void save(Student student){
		this.getHibernateTemplate().save(student);
		
	}
}

Spring使用HibernateDaoSupport操作數據
