spring提供了一個數(shù)據(jù)訪問層的類：org.springframework.orm.hibernate3.support.HibernateDaoSupport。一般是讓

dao繼承該類，然后在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，注入

資源，在set方法里傳入SessionFactory或者HibernateTemplate,然后再通過super或者this調(diào)用HibernateDaoSupport的

相應(yīng)set方法。

HibernateDao接口：

package com.dao;

public interface HibernateDao {

}

能夠在里面封裝一些經(jīng)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。就能夠注入。setOne注入?yún)?shù)sessionFactory,初始化HibernateDaoSupport的SessionFactory.

HibernateDao是用來被繼承類，能夠封裝一些經(jīng)常使用的方法。
