spring配置文件中关于事务配置总是由三个组成部分，DataSource、TransactionManager和代理机制这三部分，无论是那种配置方法，一般变化的只是代理机制这块！
　　首先我创建了两个类，一个接口类一个实现类：
package com.dao;
public interface UserDao {
public void getUser();
}
package com.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.dao.UserDao;
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
public void getUser(){
}
}
　　第一种：每个Bean都有一个代理：
