java.lang.ClassNotFoundException: org.aspectj.weaver.reflect.ReflectionWorld$Reflection……解决方案

在用Spring Aop时，发现xml中的配置完全正确，但是就是抛出异常，详细错误如下：

根据最后一个Caused by发现，原来是缺少了类，只要导入一个aspectjweaver.jar就可以了，导入包的配置如下：

    <dependency>      <groupId>org.apache.geronimo.bundles</groupId>      <artifactId>aspectjweaver</artifactId>      <version>1.6.8_2</version>    </dependency>
