Interceptors (Interceptor) are one of the most powerful features of Struts2, and can be said to be the core of struts2, which allows you to do some processing before or after action and result are executed. At the same time, interceptors allow you to modularize generic Code and act as a reusable class. Many of the features in Struts2 are do

Detailed description of interceptor in Struts2What is the interceptor?
An Interceptor is a mechanism that allows users to process functions before and after the Action is executed.The sequence of the interceptor before the action is executed is the opposite of that after the result is executed. You can see:
That is, th
Similar to Struts2, the SPRINGMVC's interceptor is the main function of the server to actually handle the request before and after some related operations. such as initialization of resources, permissions monitoring, Session settings, menu acquisition, resource cleanup, and so on.Steps:
1. Defining interceptors
Custom interceptors generally inherit from Handlerinterceptoradapter or implement the Handlerinterceptor interface. Implementing
Struts2 interceptors are similar to servlet filters. Before the Execute method of the action is executed, STRUTS2 first executes the reference in Struts.xmlInterceptor that executes the Execute method of the action after all the intercept methods of the referenced interceptor have been executed. In the Struts2 interceptor system,Struts2 's built-in interceptors complete most of the framework's operations, s
