Question

我编写此代码，该代码应为应用程序的“评论部分”或“评论部分”。我试图发送一个ArrayList（commentcontent只有2个字符串，用户和注释，并实现了Serializable）。似乎服务器将数据发送到客户端，但是在readObject（）的那一刻什么也没发生，并且代码冻结，就像他还在等待什么一样。有人可以帮助解决这个问题吗？

这是我的通信服务器处理程序

public class CommentHandler extends Thread{


    private Socket socket;
    private ObjectInputStream in;
    private ObjectOutputStream out;
    
    public CommentHandler(Socket s) throws IOException {
        this.socket=s;
        this.out = new ObjectOutputStream(s.getOutputStream());
    }
    
    @Override
    public void run() {
        try {
            this.in = new ObjectInputStream(socket.getInputStream());
            while(true) {
                try {
                    String todo = (String )in.readObject();
                    sendMessage();
                } catch (ClassNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                
            }
            
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public void sendMessage() {
                try {
                    out.writeObject(new ArrayList<CommentContent>(DataBaseAccess.getInstance().getComments(13)));
                    out.flush();
                    System.out.println("SENT");

                } catch (IOException e) {
                    System.out.println("ERROR");
                    e.printStackTrace();
                }
            
            //DataBaseAccess.getInstance().getComments(idGame);
        }
    }

这是我的通讯客户处理程序

public class CommentHandler {
    private static Socket socket;
    private static ObjectInputStream in;
    private static ObjectOutputStream out;
    
    public static void connect() throws Exception {

        if(socket!=null) return;

        socket= new Socket("localhost", 8000);
        out= new ObjectOutputStream(socket.getOutputStream());
    }
    
    public static void read() throws Exception{
        if(socket==null) return;
        //sendRequest("todo");;
        if(in == null)
            in = new ObjectInputStream(socket.getInputStream());
        
        //??????????????????????????????????????????????????????????????????????????
        System.out.println("TRY TO RECEIVE");
        ArrayList<CommentContent> comm = new ArrayList<CommentContent>((ArrayList<CommentContent>) in.readObject()) ;

        System.out.println("RECEIVED");

    }
    
    public static void sendMessage(CommentContent message) throws Exception {
        if(out == null) return;
        out.writeObject(message);
        out.flush();
    }
    
    public static void sendRequest(String todo) throws IOException {
        if(out==null) return;
        out.writeObject(todo);
        out.flush();
    }
}

请帮助。

PS。我将client.read（）调用到我的窗格的控制器中，并使用Timer类来刷新页面。

服务器-客户端通信Java。客户端冻结在函数readObject（）
