参考：

 publicvoid addByUrl() throws Exception{        String encoding="UTF-8";        String params="[{\"addTime\":\"2011-09-19 14:23:02\"[],\"iccid\":\"1111\",\"id\":0,\"imei\":\"2222\",\"imsi\":\"3333\",\"phoneType\":\"4444\",\"remark\":\"aaaa\",\"tel\":\"5555\"}]";        String path ="http://localhost:8083/xxxx/xxx/sim!add.do";        byte[] data = params.getBytes(encoding);        URL url =new URL(path);        HttpURLConnection conn = (HttpURLConnection)url.openConnection();        conn.setRequestMethod("POST");        conn.setDoOutput(true);        //application/x-javascript text/xml->xml数据 application/x-javascript->json对象 application/x-www-form-urlencoded->表单数据        conn.setRequestProperty("Content-Type", "application/x-javascript; charset="+ encoding);        conn.setRequestProperty("Content-Length", String.valueOf(data.length));        conn.setConnectTimeout(5*1000);        OutputStream outStream = conn.getOutputStream();        outStream.write(data);        outStream.flush();        outStream.close();        System.out.println(conn.getResponseCode()); //响应代码 200表示成功        if(conn.getResponseCode()==200){            InputStream inStream = conn.getInputStream();               String result=new String(StreamTool.readInputStream(inStream), "UTF-8");        }    }
