关于用spring来管理Struts中的action 所出现的问题

出现这个问题的主要原因是代理的问题

 

关于代理：

默认情况下是JDK的动态代理

   注意：JDK动态代理只能对实现了接口的类生成动态代理，而不能针对没有实现接口的类，对于没有实现接口的类只能用cglib

 

  CGLIB是针对类实现的代理，主要是对指定的类生成一个子类，覆盖其中的方法，因为是继承，所以该类或者方法最好不要申明成final

 

如何使用CGLIB实现AOP

 

*添加CGLIB库，SPRING_HOME/cglib/*.jar

* 在spring的配置文件中加入<aop:aspectj-autoproxy proxy-target-class="true"/>
