擷取當前訪問URI並儲存於session中：
String uri = request.getRequestURI();String param = "";try {if(request.getQueryString() != null) {param = new String(request.getQueryString().getBytes("ISO8859-1"),"UTF-8");}} catch (UnsupportedEncodingException e) {e.printStackTrace();}if(!param.equals("")) {uri += "?"+param;}session.put("uri", uri);
當登入失敗時跳轉到失敗頁面，當登入成功時跳轉到當前訪問的頁面或者給予提示：
下面是struts2跳轉提示頁面代碼
<%@page contentType="text/html;charset=utf-8"%><%@ taglib uri="/struts-tags" prefix="s" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><title>跳轉提示</title><script type="text/javascript" src="/js/jquery-1.4.min.js"></script><script type="text/javascript">var second=3;$(function() {$("#secondSpan").text(second+"");var fuc = function(){second-=1;$("#secondSpan").text(second+"");if(second==0) {location="${uri}";}else{setTimeout(fuc,1000);}};fuc();//開始倒計時});</script></head><body><div><h2>${curUser.username }您已成功登陸！</h2><h3> </h3><h3>頁面在<span id="secondSpan"></span>秒後將重新轉回 <a href="${uri}"></a>。如果轉入失敗，請單擊<a href="${uri}">這裡</a>。</h3> </div></body></html>
在登入處理的servlet或者action中不要做記錄，否則可能陷入迴圈。。
