struts2包继承问题
如果一个包继承了另一个包，继承到些什么东西？是继承到父包的所有action吗，拦截器也会继承吗，

------解决方案--------------------
官网找的这句话：The extends attribute is optional and allows one package to inherit the configuration of one or more previous packages - including all interceptor, interceptor-stack, and action configurations.
继承包括所有拦截器,拦截器栈,action配置
