Today found Servletresponse.sendredirect (path+ "/login.jsp") when using Sessionfilter to filter the session, sometimes not jump, can use interceptors to implement.
Added in Struts.xml:
Java code <!-- Define a author interceptor and define a default interceptor --> < interceptors> < Interceptor name= "Authorlogin" class= "Com.rating.joyintech.action.AuthorizationInterceptor"/> <interceptor-stack name= "Mystack" > <interceptor-ref name= "Defaultstack"/> <interceptor-ref name= "AuthorLogin"/> </ interceptor-stack> </interceptors> &NBSp; <default-interceptor-ref name= "MyStack"/> <global-results> <result name= "Nosession" >/login.jsp</result> </global-results>
The corresponding interceptor code is as follows:
Java code package com.rating.joyintech.action; import java.util.map; import javax.servlet.http.httpservletrequest; import org.apache.struts2.servletactioncontext; import com.opensymphony.xwork2.actioninvocation; import com.opensymphony.xwork2.interceptor.abstractinterceptor; public class authorizationinterceptor extends abstractinterceptor{ @Override public string intercept (Actioninvocation ai) throws Exception { // todo Auto-generated method stub map session = ai.getinvocationcontext (). GetSession (); &NBSP;&NBSP;&NBSP;&NBsp; httpservletrequest request = servletactioncontext.getrequest (); if (Session.get ("UserInfo") ==null && request.getrequesturi (). IndexOf ("login") ==-1) {//login.action do not intercept return "Nosession"; } else{ return ai.invoke (); } } }
