struts端如何设置action的方法为post提交的方式提交

Question

android客户端在访问struts框架搭建的服务端方法时，在struts端如何设置action的方法为post提交的方式提交(在客户端访问时需要传递一些json参数，get方式提交的无法在android端提交)；
在struts中配置的信息：
<package name="json" extends="json-default">
       <action name="selectById" class="UserAction" method="selectById">
         <result type="json"></result> <!--返回值类型设置为json,不设置返回页面-->
       </action>
</package>

该如何设置，求帮助

phone2Server方法里面有你要的
[code="java"]
package cn.itcast.web.java.client;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;

public class Phone {
public static void main(String[] args) throws Exception {

    URL url = new URL("http://127.0.0.1:8080/xxx"); 

    URLConnection urlConnection = url.openConnection();

    HttpURLConnection httpURLConnection = (HttpURLConnection) urlConnection;

    phone2Server(httpURLConnection);

    serverTophone(httpURLConnection);
}

private static void phone2Server(HttpURLConnection httpURLConnection)
        throws IOException, UnsupportedEncodingException {

    httpURLConnection.setDoOutput(true);
    OutputStream os = httpURLConnection.getOutputStream();
    PrintWriter pw = new PrintWriter(os);
    String name = "杰克";
    name = URLEncoder.encode(name,"UTF-8");
    pw.write("username="+name+"&password=123");
    pw.flush();
    pw.close();

    //设置提交方法
    httpURLConnection.setRequestMethod("POST");

    //取得服务端响应的状态码
    int code = httpURLConnection.getResponseCode();
    System.out.println(code);
}

private static void serverTophone(HttpURLConnection httpURLConnection) throws Exception {
    //接收服务端的响应
    InputStream is = httpURLConnection.getInputStream();
    byte[] buf = new byte[1024];
    int len = 0;
    while((len=is.read(buf))>0){
        String msg = new String(buf,0,len);
        System.out.println(msg);
    }
    is.close();
}

}

[/code]
