hibernate错误提示： No Hibernate Session bound to thread, and configuration does not allow creation of no

org.hibernate.HibernateException: No Hibernate Session bound to thread, andconfiguration does not allow creation of non-transactional one here

    atorg.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

    atorg.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:622)

    at com.dao.impl.MyTypeImpl.getParent(MyTypeImpl.java:29)

一直也找不到原因，后来突然发现，自己确实是没有配置事物，自己的那个操作方法名字是：

[java]  view plain  copy

1. public List<MyType> getParent();  

而事务配置为

[html]  view plain  copy

1.     <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">  
2.     <property name="sessionFactory" ref="sessionFactory"></property>  
3. </bean>  
4.   
5. <tx:annotation-driven transaction-manager="transactionManager" />  
6.   
7. <tx:advice id="txAdvice" transaction-manager="transactionManager">  
8.     <tx:attributes>  
9.         <tx:method name="Add*" propagation="REQUIRED" isolation="DEFAULT" />  
10.         <tx:method name="Delete*" propagation="REQUIRED" isolation="DEFAULT" />  
11.         <tx:method name="Update*" propagation="REQUIRED" isolation="DEFAULT" />  
12.         <tx:method name="Query*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
13.         <tx:method name="LoginInfo*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
14.         <tx:method name="QueryAll*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />          
15.     </tx:attributes>  
16. </tx:advice>  

事务里没有配置以“get”开头的方法名，所以导致使用get开发方法错误，加上<tx:method name="get*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />后问题解决，修改后的配置文件如下：

[html]  view plain  copy

1. <tx:advice id="txAdvice" transaction-manager="transactionManager">  
2.     <tx:attributes>  
3.         <tx:method name="Add*" propagation="REQUIRED" isolation="DEFAULT" />  
4.         <tx:method name="Delete*" propagation="REQUIRED" isolation="DEFAULT" />  
5.         <tx:method name="Update*" propagation="REQUIRED" isolation="DEFAULT" />  
6.         <tx:method name="Query*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
7.         <tx:method name="LoginInfo*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
8.         <tx:method name="QueryAll*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
9.         <tx:method name="get*" propagation="NOT_SUPPORTED" isolation="DEFAULT" />  
10.     </tx:attributes>  
11. </tx:advice>  

注意方法名称是否在配置的事务方法中
