谁能让它运行起来——Spring AOP无法运行

我的配置文件如下：

/aop:aspectj-autoproxy

启动的时候报错：

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0' has been injected into other beans [org.springframework.transaction.config.internalTransactionAdvisor] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.

如果不加入：
/aop:aspectj-autoproxy便能运行，，为什么呢。请大侠们看看，，我需要用到aop...

如果用的是SpringMVC ，在加载dispatcherServlet这个servlet的时候，也有一个配置文件-servlet.xml，将AOP 配置 /aop:aspectj-autoproxy 放在上面的xml文件中，试试。
