我需要一种在Java中记录此XML响应的方法。当我从Java发送请求时，将返回此内容。我需要一种打印响应描述的方法。

下面是我的Java代码：

 url = new URL(endpoint);


        connection = (HttpURLConnection) url.openConnection();
  responseCode = connection.getResponseCode();
        respTxt = connection.getResponseMessage();
        System.out.println("Status code after sending the the payload to mtn => " + responseCode + " Now waiting for response: ");
        Object vm = connection.toString();
        //   BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        PrintWriter pw = new PrintWriter(connection.getOutputStream());

        // send xml to jsp
        // pw.write(buffer, 0, bytes_read);
        // pw.close();
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
        }

如果响应代码不是200或2xx或3xx，请使用getErrorStream（）而不是getInputStream（）。

请参阅How to get response body using HttpURLConnection, when code other than 2xx is returned?

    url = new URL(endpoint);

            connection = (HttpURLConnection) url.openConnection();
            responseCode = connection.getResponseCode();
            respTxt = connection.getResponseMessage();
            System.out.println("Status code after sending the the payload to mtn => " + responseCode + " Now waiting for response: ");
            Object vm = connection.toString();
            //   BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            //PrintWriter pw = new PrintWriter(connection.getOutputStream());

            // send xml to jsp
            // pw.write(buffer, 0, bytes_read);
            // pw.close();
            BufferedReader in;

            if(responseCode >= 200 && responseCode  < 400) {
                in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            } else {
                in = new BufferedReader(new InputStreamReader(connection.getErrorStream()));
            }
            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                System.out.println(inputLine);
            }
