hibernate 拦截器循环依赖的Spring配置

Question

我正在尝试实现 hibernate 拦截以在基于 spring 的项目中创建日志表，但我在配置文件上苦苦挣扎。
一切都工作得很好，但是拦截器永远不会触发。

我是我的拦截器，我有 @Autowired 我的 Dao，因为我需要访问它以在 LogTable 中保存新输入。所有 Daos 在参数中都有 session 工厂，所以当我尝试添加

<property name="entityInterceptor">
    <bean class="com.mypackage.MyLoggingInterceptor"></bean>
</property>

我对 sessionFactory bean 有循环依赖:

java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in URL [URL]: Cannot resolve reference to bean 'MyLoggingInterceptor' while setting bean property 'entityInterceptor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyLoggingInterceptor': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.mypackage.UserLogDao com.mypackage.MyLoggingInterceptor.userLogDao; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'UserLogDao' defined in URL [URL]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'sessionFactory': FactoryBean which is currently in creation returned null from getObject

如果我不添加 entityInterceptor 属性，我的程序可以正常工作，但永远不会调用拦截器。我应该怎么做才能解决这种循环依赖？

可以通过使用@Lazy注释@Autowired属性来实现循环依赖。
