action端发请求并且处理

我们一般是在前端发请示，然后在struts的action端来处理请求。

如果有这样的需求，需要在action里得到某个“.do”请求的结果，这时候可以用流来解决。如下：

private String getHighWayAndMile(double x,double y,HttpServletRequest request){String serverName = request.getServerName();String serverPort = new Integer(request.getServerPort()).toString();String urlString = "http://"+serverName+":"+serverPort+"/gis_web/webmap/UtilAction.do";    String param = "tools=LATESTPOINT&x="+x+"&y="+y+"&IS_FOR_PHONE=1";    StringBuffer sb = new StringBuffer();    try {    URL U = new URL(urlString+"?"+param);    URLConnection connection = U.openConnection();    connection.connect();    BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));    String line;    while ((line = in.readLine())!= null){    sb.append(line);    }    in.close(); } catch (IOException e) {e.printStackTrace();} return sb.toString();}
