Spring AOP+ehCache简单缓存系统解决方案

AOP嘛，少不了拦截器,先创建一个实现了MethodInterceptor接口的拦截器,用来拦截Service/DAO的方法调用，拦截到方法后，搜索该方法的结果在cache中是否存在，如果存在，返回cache中的缓存结果，如果不存在，返回查询数据库的结果，并将结果缓存到cache中。

Exception in thread "main" org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'defaultCacheManager': Bean with name 'defaultCacheManager' has been injected into other beans [ehCache] 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.?????????

 

-----有时候，在SPRING中两个类互相含有对方的声明，一般情况这是不允许并且极可能是有错误的。
会报这个错：(上面的error)

上面不是有我写的例子吗，好长时间了，忘的差不多了，有可能<ehcache> 这个xml配置的问题

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'defaultCacheManager': Bean with name 'defaultCacheManager' has been injected into other beans [ehCache] 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.我遇到这样的错误，请问怎么解决？？
