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：

public List<MyType> getParent();

而事务配置为

     <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><tx:annotation-driven transaction-manager="transactionManager" /><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="Add*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Delete*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Update*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Query*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /><tx:method name="LoginInfo*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /><tx:method name="QueryAll*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /></tx:attributes></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：

<tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="Add*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Delete*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Update*" propagation="REQUIRED" isolation="DEFAULT" /><tx:method name="Query*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /><tx:method name="LoginInfo*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /><tx:method name="QueryAll*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /><tx:method name="get*" propagation="NOT_SUPPORTED" isolation="DEFAULT" /></tx:attributes></tx:advice>
