Configuration and use of SPRINGMVC interceptors:
1. Customize the interceptor to implement the Handlerinterceptor interface.

Package Com.bybo.aca.web.interceptor;import Javax.servlet.http.httpservletrequest;import Javax.servlet.http.httpservletresponse;import Org.springframework.web.servlet.handlerinterceptor;import Org.springframework.web.servlet.modelandview;public class Login implements Handlerinterceptor {@Override public voi D aftercompletion (HttpServletRequest HttpRequest, HttpServletResponse HttpResponse, Object arg2, Exception arg3 ) throws Exception {} @Override public void Posthandle (HttpServletRequest arg0, HTTPSERVLETR Esponse arg1, Object arg2, Modelandview arg3) throws Exception {} @Override public boolean PR Ehandle (HttpServletRequest request, HttpServletResponse response, Object object) throws Exception {/*ht           Tpservletrequest HttpRequest = (httpservletrequest) request;       HttpServletResponse HttpResponse = (httpservletresponse) response;*/String urlstring = Request.getrequesturi ();             Olforum/forumlist.html Impersonation Login Page if (Urlstring.endswith ("forumlist.html")) {return true;               }//path requested by String Contextpath=request.getcontextpath (); /*httprequest.getrequestdispatcher ("/olforum/forumlist"). Forward (HttpRequest, httpresponse); */* Response.sendredirect (contextpath+ "/olforum/forumlist.html"); */Response.sendredirect (ContextPath + "/olForum/          Forumlist.html?login=aaa ");        return false;        /*httpresponse.sendredirect (Httprequest.getcontextpath () + "/olforum/forumlist.html"); return;*/}}
