Java 等待进程类的方法不'；不归

我的代码中有一个Process类，当我试图从inputbuffer读取大量数据时，它无法读取inputbufferreader数据，而Process类的waitfor方法从未返回任何内容

• 此问题发生在live server中
• 但下面的代码运行良好，并从本地服务器的inputbuffer读取所有数据

  private static JSONObject ExecJniApp(String inputJsonString) throws JniException
  {
  int exitStatus = 0;
  String workingDirectory = JniSettings.getJniAppDirectory();
  String command = workingDirectory + binaryName;
  System.out.println("ExecJniApp: inputJsonString: " + inputJsonString);
  String outputString = "";
  try
  {
      Process p = Runtime.getRuntime().exec(command, null, new File(workingDirectory));
      // send input vi stdin
      BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
      writer.write("\n>>>>>>>>>>");
      writer.write(inputJsonString);
      writer.write("<<<<<<<<<<\n");
      writer.flush();
      if (JniSettings.isLinux())
      {
          p.waitFor();
      }
      else
      {
          // System.out.println("ExecJniApp: windows wait for");
      }
      BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
      for (;;)
      {
          String line = reader.readLine();
          if (line == null)
          {
              break;
          }
          // System.out.println(line);
          outputString += line + "\n";
      }
      // exit code of command and log error detail
      // exit status = 0 -> Success
      exitStatus = p.exitValue();
      if (exitStatus != 0)
      {
          System.out.println("ExecJniApp: inputJsonString: " + inputJsonString);
          System.out.println("ExecJniApp: outputString:\n" + outputString);
          throw new Exception("Exit status other than zero :- " + exitStatus + "\noutput: ");
      }
  }
  catch (Exception e)
  {
      // System.out.println("ExecJniApp failed");
      e.printStackTrace();
      throw new JniException("JniInterface failed");
  }
  System.out.println("ExecJniApp: outputString:\n" + outputString);
  int index1 = outputString.indexOf(">>>>>>>>>>");
  if (index1 == -1)
  {
      // System.out.println("ExecJniApp failed, Invalid output format");
      throw new JniException("ExecJniApp failed, Invalid output format");
  }
  index1 += 10;
  int index2 = outputString.indexOf("<<<<<<<<<<");
  if (index2 == -1 || index2 <= index1)
  {
      // System.out.println("ExecJniApp failed, Invalid output format");
      throw new JniException("ExecJniApp failed, Invalid output format");
  }
  String outputJsonString = outputString.substring(index1, index2);
  // System.out.println("ExecJniApp: outputJsonString: " + outputJsonString);
  JSONParser parser = new JSONParser();
  JSONObject obj = null;
  try
  {
      obj = (JSONObject) parser.parse(outputJsonString);
  }
  catch (ParseException e)
  {
      // System.out.println("ExecJniApp failed, Json parse failed");
      e.printStackTrace();
      throw new JniException("JniInterface failed, Json parse failed");
  }
  Object errorObject = obj.get("error");
  if (errorObject != null)
  {
      String errorString = errorObject.toString();
      // System.out.println("ExecJniApp failed, " + errorString);
      throw new JniException("ExecJniApp failed, " + errorString);
  }
  return obj;
  }

  编写。（写命令是什么？命令执行C++ exe文件，而不是描述它。这里我有更改代码以完全理解它的全部场景。
