No Hibernate Session bound to thread纠结了很久

这个问题我在网上看了好多资料，大概就是没有配置transaction，而我已经配置了

<!-- similarly, don't forget the PlatformTransactionManager -->

</beans>

 

@Component
public class TestConfiguration {
private SessionFactory mySessionFactory;

public SessionFactory getMySessionFactory() {
return mySessionFactory;
}
@Resource(name="mySessionFactory1")

public void setMySessionFactory(SessionFactory mySessionFactory) {
this.mySessionFactory = mySessionFactory;
}

@Test
public void testTransactionManager(){
Department department = new Department();
department.setName("吼吼吼");
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
TestConfiguration tConfiguration =  (TestConfiguration) applicationContext.getBean("testConfiguration");
tConfiguration.getMySessionFactory().getCurrentSession().save(department);
}

}

但是就是一直出No Hibernate Session bound to thread错误。。。

后来我发现<aop:pointcut id="productServiceMethods" expression="execution(public * com.yuxuan.crm.domain.TestConfiguration.*(..))"/>定义的是运行TestConfiguration里面的方法才自动管理实务，而我是junit testTransactionManager()来测试的，是不是这样测试并没有经过spring的先getBean，在执行相应execution方法的流程？

我有加了一个方法

@Test
public void testTransactionManager(){
Department department = new Department();
department.setName("吼吼吼");
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
TestConfiguration tConfiguration =  (TestConfiguration) applicationContext.getBean("testConfiguration");
tConfiguration.getMySessionFactory().getCurrentSession().save(department);
}
@Test
public void test3(){
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
TestConfiguration tConfiguration =  (TestConfiguration) applicationContext.getBean("testConfiguration");
tConfiguration.testTransactionManager();
}

junit test3()这次运行正确了!那么我的推断就是对的，必须用getBean得出的对象来执行execution的方法，而最开始我

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
TestConfiguration tConfiguration =  (TestConfiguration) applicationContext.getBean("testConfiguration");
tConfiguration.getMySessionFactory().getCurrentSession().save(department);

getbean之后是执行的save方法，并不是execution(public * com.yuxuan.crm.domain.TestConfiguration.*(..))这定义的方法，而用Junit测试该方法和spring并没有关系（没有开启事务管理没有创建bean）！

总结:出现No Hibernate Session bound to thread情况，一种是事务声明管理没有配置或者配置错误

还有一种情况是执行的方法并没有设置在<aop:pointcut execution="">中!
