Question

java로 TCP 프로젝트를 만들고 있습니다. 마이크로 컨트롤러에서 직렬 통신으로 java에서 TCP 연결을 만들고 싶습니다. 멀티 스레딩을 사용하고 싶습니다.

하지만 내 서버와 클라이언트를 실행할 때 내 클라이언트에서 내 서버로 메시지를 보냅니다. 그럼 난 tcpserver는에서 다음과 같은 오류가 있습니다

import java.io.*; 
import java.net.*; 
import java.io.IOException; 
import jssc.SerialPort; 
import jssc.SerialPortException; 
import java.util.Scanner; 
import java.util.logging.Level; 
import java.util.logging.Logger; 
import jssc.SerialPortList; 
import jssc.*; 
import jssc.SerialPort; 
import jssc.SerialPortException; 

class TCPServer 
{ 
    public static void main(String argv[]) throws Exception 
    { 
     ServerSocket welcomeSocket = new ServerSocket(6789); 
     SerialPort serialPort = new SerialPort("COM3"); 

     while(true) 
     { 
      Socket connectionSocket = welcomeSocket.accept(); 
      if (connectionSocket != null) 
      { 
       Client client = new Client(connectionSocket); 
       client.start(); 
      } 
     } 
    } 
} 

class Client extends Thread 
{ 
    private Socket connectionSocket; 
    private String clientSentence; 
    private String capitalizedSentence; 
    private BufferedReader inFromClient; 
    private DataOutputStream outToClient; 

    public Client(Socket c) throws IOException 
    { 
     connectionSocket = c; 
    } 

    public void run() 
    { 
     try 
     {  
      inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream())); 
      outToClient = new DataOutputStream(connectionSocket.getOutputStream()); 
      clientSentence = inFromClient.readLine(); 
      capitalizedSentence = clientSentence.toUpperCase() + '\n'; 
      outToClient.writeBytes(capitalizedSentence); 
      serialPort.openPort();//Open serial port 

      serialPort.setParams(SerialPort.BAUDRATE_115200, 
          SerialPort.DATABITS_8, 
          SerialPort.STOPBITS_1, 
          SerialPort.PARITY_NONE); 
      System.out.println("Received: " + clientSentence); 
      serialPort.writeString(clientSentence + "\r\n"); 
      //Thread.sleep(1000); 
      String buffer = serialPort.readString();//Read 10 bytes from seri 
      // Thread.sleep(1000); 

      outToClient.writeBytes(buffer); 
      System.out.println(buffer); 
      serialPort.closePort(); 
      connectionSocket.close(); 

     } catch (IOException ex) { 
      Logger.getLogger(Client.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    } 

} 

나의하여 TcpClient 코드 :

import java.io.*; 
import java.net.*; 

class TCPClient 
{ 
    public static void main(String argv[]) throws Exception 
    { 
     while(true){ 
     String sentence;    
     String modifiedSentence;  

     Socket clientSocket = new Socket("localhost", 6789); 

     BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in)); 
     DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());   
     BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); 

     sentence = inFromUser.readLine(); 
     outToServer.writeBytes(sentence + '\n'); 
     modifiedSentence = inFromServer.readLine(); 
     System.out.println("FROM SERVER: " + modifiedSentence); 

     clientSocket.close(); 
     } 
    } 
}

          SerialPort.PARITY_NONE);//Set params. Also you can set params by this string: serialPort.setParams(9600, 8, 1, 0); 
     Scanner input = new Scanner(System.in); 
     String scommand = input.nextLine(); 

     serialPort.writeString(scommand + "\r\n"); 

     String buffer = serialPort.readString();//Read 10 bytes from serial port 

     System.out.println(buffer); 

     serialPort.closePort(); 

    } 
    catch (SerialPortException ex) { 
     System.out.println(ex); 
    } 
} 
} 
} 

수 있습니다 anybo 도와 줘? 그들이 사용하는 예제를 검토 할 때 https://code.google.com/archive/p/java-simple-serial-connector/

내가 아닌 곳

을 클라이언트 클래스의 tcpserver는 클래스에 설정을 참조

SerialPort serialPort = new SerialPort("COM1"); 

serialPort.openPort(); 

이 호출됩니다.

그래서 openPort를 호출하기 전에 TCPServer 클래스 대신 ClientClass에서 serialPort를 초기화해야 할 수도 있습니다.

UnsupportedOperationException을 던지는 openPort 메소드에 대한 참조가 없습니다.
