PROPAGATION_REQUIRED


二&＃xff1a;所有Bean共享一个代理基类


PROPAGATION_REQUIRED


三&＃xff1a;使用拦截器


PROPAGATION_REQUIRED *Dao transactionInterceptor


四&＃xff1a;使用tx标签配置的拦截器(也是最常用的)

五&＃xff1a;全注解


此时在DAO上需加上&＃64;Transactional注解&＃xff0c;如下&＃xff1a;

package com.spring.dao;import java.util.List;import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;import com.spring.domain.User;&＃64;Transactional
&＃64;Component("userDao")
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {public List listUsers() {return this.getSession().createQuery("from User").list();}...
}
