关于 Spring3 报org.aopalliance.intercept.MethodInterceptor问题解决方法

运行环境：Spring3.1.0.RELEASE
报错信息如下：

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [SpringConfig_Jdbc.xml]; nested exception is java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor (省略)... Caused by: java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [SpringConfig_Jdbc.xml]; nested exception is java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor(省略)...Caused by: java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

出现了java.lang.NoClassDefFoundError:的错误，首先想到的就是少包，在网上搜搜了，果然是少了一个叫aopalliance.jar的jar包，下载这个包，加到路径里就OK了。
