struts2如何让获取包含参数的完整的url？

有些页面需要用户登录后才可以访问，为了实现登录成功后跳转回继续访问 于是记录下跳转到登录页面前要访问的页面的url，如何取得这个url 包含它的 ？后面带的参数
我这里有个方法但是只是取得action的名字具体参数不知道如何取得，求高手帮助。
private void setGoingToURL(Map session, ActionInvocation invocation){
String url = "";
String namespace = invocation.getProxy().getNamespace();
if (StringUtils.isNotBlank(namespace) && !namespace.equals("/")){
url = url + namespace;
}
String actionName = invocation.getProxy().getActionName();
if (StringUtils.isNotBlank(actionName)){
url = url + "/" + actionName + ".action";
}
session.put(GOING_TO_URL_KEY, url);
}
}

Answer 1

.....获取 request对象,request对象有个方法叫getQueryString.....你懂的..

接分..

Answer 2

public class Login implements ServletRequestAware{
HttpServletRequest request;
public String login(){
Map map = request.getParameterMap();
Iterator it = map.keySet().iterator();
String paramStr = "";
while(it.hasNext()){
String key = it.next().toString();
String value = request.getParameter(key);
paramStr += key + "=" + value + "&";
}
//完整的请求
System.out.println(request.getRequestURL()+"?"+paramStr);
return null;
}

public void setServletRequest(HttpServletRequest arg0) {
this.request = arg0;
}
}
不知道有什么更好的方式能说明，我写了一个方法，
大体的思路是：实现一个 ServletRequestAware 接口，通过setServletRequest得到request，然后从request得取参数名称集合，遍历集合，从请求中获取value。再将其拼在一起。
哈哈，好像有点笨，但是只能想到这么多了，希望对你有帮助。

里面拿这个参数的值。方法二：String param = ServletActionContext.getRequest().getParameter(

你好，请看我的问题补充里面，如何生成完整的url

哥们这里应该有你想要的（获得访问者来源和request.getHeader方法的内容）：
System.out.println("Protocol: " + request.getProtocol());
System.out.println("Scheme: " + request.getScheme());
System.out.println("Server Name: " + request.getServerName() );
System.out.println("Server Port: " + request.getServerPort());
System.out.println("Protocol: " + request.getProtocol());
System.out.println("Server Info: " + getServletConfig().getServletContext().getServerInfo());
System.out.println("Remote Addr: " + request.getRemoteAddr());
System.out.println("Remote Host: " + request.getRemoteHost());
System.out.println("Character Encoding: " + request.getCharacterEncoding());
System.out.println("Content Length: " + request.getContentLength());
System.out.println("Content Type: "+ request.getContentType());
System.out.println("Auth Type: " + request.getAuthType());
System.out.println("HTTP Method: " + request.getMethod());
System.out.println("Path Info: " + request.getPathInfo());
System.out.println("Path Trans: " + request.getPathTranslated());
System.out.println("Query String: " + request.getQueryString());
System.out.println("Remote User: " + request.getRemoteUser());
System.out.println("Session Id: " + request.getRequestedSessionId());
System.out.println("Request URI: " + request.getRequestURI());
System.out.println("Servlet Path: " + request.getServletPath());
System.out.println("Accept: " + request.getHeader("Accept"));
System.out.println("Host: " + request.getHeader("Host"));
System.out.println("Referer : " + request.getHeader("Referer"));
System.out.println("Accept-Language : " + request.getHeader("Accept-Language"));
System.out.println("Accept-Encoding : " + request.getHeader("Accept-Encoding"));
System.out.println("User-Agent : " + request.getHeader("User-Agent"));
System.out.println("Connection : " + request.getHeader("Connection"));
System.out.println("Cookie : " + request.getHeader("Cookie"));
System.out.println("Created : " + session.getCreationTime());
System.out.println("LastAccessed : " + session.getLastAccessedTime());
