Java Socket 發送數據

Question

我創建了兩個類，一個服務器和一個客戶端，我通過套接字輸入和輸出流發送數據但是不能發送多條消息？

服務器：

public class SOK_1_SERVER {

    public static void main(String[] args) throws Exception
    {

        SOK_1_SERVER Sever = new SOK_1_SERVER();
        Sever.run();
    }

    private void run() throws Exception {
        ServerSocket SRVSOCK = new ServerSocket(444);
        //Waits both client and server to accept and we return 
        //a socket
        Socket SOCK = SRVSOCK.accept();
        //Once accepted 
        InputStreamReader isr = new InputStreamReader(SOCK.getInputStream());
        BufferedReader br = new BufferedReader(isr);

        String message = br.readLine();
        System.out.println("I read: " + message + "from Client");

        if(message != null)
        {
            //Sending message back to client 
            PrintStream ps = new PrintStream(SOCK.getOutputStream());
            ps.println("Message Received");
            ps.println("Send from Server");
        }
    }
}

客戶

public class SOK_1_CLIENT {

    public static void main(String[]args) throws Exception
    {
        SOK_1_CLIENT client = new SOK_1_CLIENT();
        client.run();
    }

    private void run() throws Exception {
        Socket SOCK = new Socket("localhost",444);
        PrintStream ps = new PrintStream(SOCK.getOutputStream());
        ps.println("Hello to Server from client");

        InputStreamReader ir = new InputStreamReader(SOCK.getInputStream());
        BufferedReader br = new BufferedReader(ir);

        String message = br.readLine();

        System.out.println(message);

    }

}

它只輸出收到的消息，但我認為這是因為我需要一個循環來繼續檢查新消息，但不確定，因為我剛剛開始查看套接字。

在您的客戶端類中，您需要迭代 bufferedReader 。

代替

 String message = br.readLine();

 System.out.println(message);

用這個，

 String message ;
 while((message = br.readLine())!=null) {
     System.out.println(message);
 }
