java發(fā)送http請求,無需等待返回結果

與B項目進行交互,由于B項目一些原因,請求處理緩慢.A項目等待返回結果需要很久...現(xiàn)只需發(fā)送數(shù)據(jù)無需判斷發(fā)送成功失敗與否,求教如何操作???以下是發(fā)送get請求的代碼 public static String doGet(String HTTP_URL, Object object) { BufferedReader reader = null; String result = null; StringBuffer httpUrl = new StringBuffer(HTTP_URL); StringBuffer sbf = new StringBuffer(); try { System.out.println(httpUrl.toString()); URL url = new URL(httpUrl.toString()); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); // 請求方式設置 POST connection.setRequestMethod("GET"); // 設置維持長連接 connection.setRequestProperty("Connection", "Keep-Alive"); // 設置文件字符集: connection.setRequestProperty("Charset", "UTF-8"); // 開始連接請求 connection.connect(); OutputStream out = connection.getOutputStream(); out.write((object.toString()).getBytes()); out.flush(); out.close(); if (connection.getResponseCode() == 200) { System.out.println("連接成功,傳送數(shù)據(jù)..."); InputStream is = connection.getInputStream(); reader = new BufferedReader(new InputStreamReader(is, "UTF-8")); String strRead = null; while ((strRead = reader.readLine()) != null) { sbf.append(strRead); sbf.append("\r\n"); } reader.close(); result = sbf.toString(); if (result.equals("1")) { return "1"; } else if(result.equals("0")) { return "0"; } else { return result; } } else { System.out.println("連接失敗,錯誤代碼:"+connection.getResponseCode()); } } catch (Exception e) { e.printStackTrace(); } return null; }

 public static String doGet(String HTTP_URL, Object object) {
        BufferedReader reader = null;
        String result = null;
        StringBuffer httpUrl = new StringBuffer(HTTP_URL);
        StringBuffer sbf = new StringBuffer();
        try {
            System.out.println(httpUrl.toString());
            URL url = new URL(httpUrl.toString());
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoOutput(true);
            connection.setDoInput(true);
            // 請求方式設置 POST
            connection.setRequestMethod("POST");
            // 設置文件字符集:
            connection.setRequestProperty("Charset", "UTF-8");
            // 開始連接請求
            connection.connect();
            OutputStream out = connection.getOutputStream();
            out.write((object.toString()).getBytes());
            out.flush();
            out.close();
            if (connection.getResponseCode() == 200) {
                System.out.println("連接成功,傳送數(shù)據(jù)...");
               
            } else {
                System.out.println("連接失敗,錯誤代碼:"+connection.getResponseCode());
