must be of type [org.aopalliance.aop.Advice]错误问题

我使用的是hibernate4+spring3，练习事务管理，运行程序报错

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService' defined in file [D:\Program-exercise\J2EE\spring_1800_hibernate_transaction\bin\com\service\UserService.class]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Unexpected AOP exception; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'org.springframework.transaction.interceptor.TransactionInterceptor#0' must be of type [org.aopalliance.aop.Advice], but was actually of type [org.springframework.transaction.interceptor.TransactionInterceptor]

网上google了，说什么发现 aopalliance-1.0.jar 和 aopalliance-alpha1.jar 两个包冲突了，去掉后者就行了。

问题是，我压根就没有在引入的jar包里面找到这个上面的这两个jar包的影子，真的不知道怎么解决这个问题，求教，非常感谢。请详细点，谢谢

你好，是尚学堂的代码，bean配置文件是

应该不是，很有可能是jar包冲突，但是真的具体不知道怎么检查是哪两个包冲突 --------------------编程问答-------------------- 没有人来解答吗？
