Spring：没有Hibernate Session绑定到线程，并且配置不允许在此处创建非事务性会话

Question

我正在创建一个简单的Web应用程序，以显示行并将其添加到oracle数据库（Regions表）中。 可悲的是我在标题中遇到了异常。 不幸的是，我已经看到与此类似的问题，但没有任何帮助。

我做错了什么？ 我知道这与交易有关。 我已经将Service标注为@Transactional ，但是它并不能解决我的问题。

是否有人可以检查Service imports是否正确。

如果需要更多内容，请发表评论。

Answer 1

将此代码从dispatcher-servlet.xml移出

<beans:bean id="regionsDao" class="facade.RegionsDaoImpl"/>

<beans:bean id="regionService" class="facade.RegionServiceImpl"/>

到applicationContext.xml ：

<bean id="regionsDao" class="facade.RegionsDaoImpl"/>

您不需要<bean/>的RegionServiceImpl，因为您在服务impl类上具有@Service 。 在applicationContext.xml添加

<context:component-scan base-package="facade" />

在您的RegionServiceImpl类中，导入实际上应该是：

import org.springframework.transaction.annotation.Transactional;

Answer 2

我的猜测是您的@Transactional服务没有由Spring AOP系统正确地检测。 可以通过在事务方法中放置一个断点并检查调用堆栈来验证这一点。 Spring使用CGLIB生成代理类，因此，如果一切正常，您应该会看到一些异常的类名称（请查找“ $ EnhancerByCGLIB”）

Answer 3

在服务对象中，您导入了错误的事务注释。 您正在使用的是Java native（EJB），春季是：org.springframework.transaction.annotation.Transactional

因此，只需更改此行

导入javax.transaction.transactional

与

导入org.springframework.transaction.annotation.Transactional

在RegionServiceImpl中。
