使用HttpURLConnection模拟创建url连接，当有中文时会有乱码，进行如下操作

            String data = "bankAcctName=陈寄文";
           System.out.println(data);
           URL url = new URL("http://localhost/bankcardcert/bankCardValidate.htm");
           StringBuffer bankXmlBuffer = new StringBuffer();
           //创建URL连接，提交到银行卡鉴权，获取返回结果
           HttpURLConnection connection = (HttpURLConnection) url.openConnection();
           connection.setRequestMethod("GET");
           connection.setDoOutput(true);
           connection.setRequestProperty("User-Agent", "directclient");
            PrintWriter out = new PrintWriter(new OutputStreamWriter(connection.getOutputStream(),"utf-8"));
            out.println(data);
           out.close();
           BufferedReader in = new BufferedReader(new InputStreamReader(connection
                   .getInputStream()));

           String inputLine;

           while ((inputLine = in.readLine()) != null) {
               bankXmlBuffer.append(inputLine);
           }
           in.close();
           System.out.println(bankXmlBuffer.toString());
