Spring整合Hibernate获得HIbernateTemplate之HibernateDaoSupport

通过继承HibernateDaoSupport来获得HibernateTemplate（最好使用IoC来注入）

 

dao层代码

package com.lbx.dao.impl;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.lbx.dao.LogDAO;
import com.lbx.model.Log;

public class LogDAOImpl extends HibernateDaoSupport implements LogDAO {

	public void save(Log log) {

		//this.save(log);
		this.getHibernateTemplate().save(log);
		//用于测试回滚，默认的时候是RuntimeException
		//throw new RuntimeException("运行的时候出错了");
	}

}
