1、你一定使用的spring+hibernate 
2、你一定在applicationContext.xml檔案中寫了事務配置如下： 

1.     <tx:advice id="txAdvice" transaction-manager="transactionManager">  
2.         <tx:attributes>  
3.             <tx:method name="save*" rollback-for="Exception" />  
4.             <tx:method name="insert*"
    rollback-for="Exception" />  
5. ollback-for="Exception" />  
6.             <tx:method name="get*" read-only="true"/>  
7.         </tx:attributes>  
8.     </tx:advice>  

1. <init-param>  
2.     <param-name>flushMode</param-name>  
3.     <param-value>AUTO</param-value>  
4. </init-param>
