Struts2 Study Notes (10) -- custom interceptor and struts2 Study Notes The Struts2 interceptor is implemented based on the idea of AOP, while the implementation of AOP is based on dynamic proxy. The Struts2 interceptor intercepts an Action before or after it is accessed, and the Struts2 interceptor is pluggable. The St

This function is very important for the user experience. It is actually very easy to implement. The interceptor code is as follows: Package go. derek. advice; import go. derek. entity. user; import go. derek. util. commonChecks; import go. derek. util. constant; import java. util. map; import javax. servlet. http. httpServletRequest; import org. apache. struts2.StrutsStatics; import org. springframework. b

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

One: theoretical preparation Interceptor : The Interceptor is a component that spring MVC provides, which can be executed after the client requests execution, and then logically processed after execution, similar to filter filters in the servlet. Interceptor Action : Reference the execution time of the interceptor we c

Summary: The Interceptor is a very important component of struts2 and an extremely subtle part of struts2. Many functions of struts2 are implemented through these interceptors, such as exception handling, file Upload request parameter assignment, data verification, and other functions are implemented in the interceptor. To thoroughly understand the interceptor, i

MultiselectInterceptor the interceptor processes the defaultStack 12th position, which is used to process the select tag where no option is selected. The logic of this interceptor is very similar to that of the CheckboxIntercept interceptor, which is almost identical. When no select tag (multiple = "multiple") is selected, the select tag is not selected, which is

ReferenceWhat I want to know here is that multiple parameters with the same name will be automatically placed in the list or array. I want to know how to implement it, because one parameter is different from multiple parameters with the same name:Request. getparameterRequest. getparametervalues First, let's explain: Struts or interceptor provided by xworlk operate on the map of the encapsulated parameters. I believe you have seen this sentence. (In ch
