generic interceptor

As we all know, when we use STRUTS2 for project development, if we configure an interceptor for an action, the interceptor intercepts all the methods within that action. However, in some cases, we do not need to intercept all the methods, just want to intercept the specified method, at this time we need to use the Struts2 interceptor method filtering features. In

The difference between filters and interceptors:　　① interceptors are based on the reflection mechanism of Java, and filters are based on function callbacks.The ② interceptor is not dependent on the servlet container, and the filter relies on the servlet container.The ③ interceptor only works on action requests, while filters can work on almost all requests.The ④ interce
