使用JSON传递接收集合，对象json for java

//发送方
public static void main(String[] args) {
		String mobiles = "15810022404";
		String content = "发送远程API测试短信。。。";
		boolean needReport = true;
		String xcode="01201112";//01为各平台短信子号，201112为流水号（000000－999999）
		String uname = "tudou";
		content = EncryptUtils.encodeBufferBase64(content.getBytes());// base64编码，防止乱码
		String sendtime = DateUtils.getNowTime();
		uname = EncryptUtils.encodeBufferBase64(uname.getBytes());
		Map<String, Object> map=new HashMap<String, Object>();//使用Map集合
		
		map.put("uname", uname);
		Send s=new Send();
		s.setContent(content);
		s.setStarttime(DateUtils.parseDate(sendtime));
		s.setMobile(mobiles);
		s.setNeedReport(needReport);
		s.setXcode(xcode);
		map.put("data", s);//将对象放入Map
		String md5 = MD5Utils.getInstance().getMD5ofStr(JSON.toJSONString(s)+MD5Utils.k1);
		map.put("md5", md5);
		new SmsSendTest().testSendSms(JSON.toJSONString(map));//直接将Map转换成JSON传递
	}

接收方：

public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		PrintWriter out = response.getWriter();
		String json = request.getParameter("json").toString();
		JSONObject jo = JSON.parseObject(json);
		String md5 = jo.getString("md5");
		String data = jo.getString("data");
		System.out.println(data);
		Send send = JSON.parseObject(data, Send.class);
		String content = new String(EncryptUtils.decodeBufferBase64(send
				.getContent()));
		String uname = jo.getString("uname");
		String upwd = jo.getString("upwd");
		uname = new String(EncryptUtils.decodeBufferBase64(uname));
		boolean needReport = send.isNeedReport();
