Spring framework3.2整合hibernate4.1报错:No Session found for current thread
<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="add*" propagation="REQUIRED"/> <tx:method name="create*" propagation="REQUIRED"/> <tx:method name="insert*" propagation="REQUIRED"/> <tx:method name="*" read-only="true" /> </tx:attributes> </tx:advice> <aop:config proxy-target-class="true"> <aop:advisor advice-ref="txAdvice" pointcut="execution(* net.noday..service..*.*(..))" /> </aop:config>
getCurrentSession需要做如下配置:
<propertyname="current_session_context_class" >thread</property>
1. 前者打开一个新的,后者当前有session的话,则是使用当前的session,没有的话则创建一个新的;
2. 如果使用前者获得一个session的话,需要手动关闭session,使用后者,当事务提交,session会自动关闭,如果再关闭session则会报如下异常:Session has already closed;
3. sf.getCurrentSession方法需要在hibernate.cfg.xml做如下配置:
<propertynamepropertyname="current_session_context_class" >thread</property>
没有配置的话会报如下异常:org.hibernate.HibernateException:No CurrentSessionContext configured!
