java - 在 Java 中没有通过 TCP 接收所有消息？

Question

我有一个 tcp 套接字发送这样的三行

        out2.println("message1\n");
        out2.println("message2\n");
        out2.println("message3\n");

另一个 tco 套接字接收并显示这些消息，就像这样

        System.out.println(in.readLine());
        System.out.println(in.readLine());
        System.out.println(in.readLine());

但只有第一条消息会被接收和显示，之后我发送的任何消息都不会。

编辑:这是代码

    private void buttonActionPerformed(java.awt.event.ActionEvent evt) {                                       
    try {
        // TODO add your handling code here:
        String ipAddress = ipTextArea.getText();
        sourceSocket = new Socket(ipAddress,32323);
        out = new PrintWriter(sourceSocket.getOutputStream(), true);
        in = new BufferedReader(new InputStreamReader(sourceSocket.getInputStream()));
        System.out.println(in.readLine());
        System.out.println(in.readLine());
        System.out.println(in.readLine());
    } catch (UnknownHostException ex) {
        Logger.getLogger(DESWashView.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(DESWashView.class.getName()).log(Level.SEVERE, null, ex);
    }


}       

cWashStations 也是从按钮事件中调用的:

public void cWashStations(){
Thread washThread = new Thread(){
    @Override
    public void run(){
        try {
            sSocket2 = new ServerSocket(32323);
            Thread stationThread = new Thread(){
                @Override
                public void run(){
                    try {
                        washSocket = sSocket2.accept();
                        out2 = new PrintWriter(washSocket.getOutputStream(), true);
                        in2 = new BufferedReader(new InputStreamReader(washSocket.getInputStream()));
                        out2.println("hello from attendant3423\n\n");
                        out2.flush();
                        out2.println("hello from attendant3423\n\n");
                        out2.println("1");
                        while(running){
                            }
                        } catch (IOException ex) {
                            Logger.getLogger(DESAttendantView.class.getName()).log(Level.SEVERE, null, ex);
                        }
                    }
                 };
                 stationThread.start();

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

        }
    };
    washThread.start();
}

如果您使用 println()，请不要在字符串末尾添加 \n。
