java 中 sockets 的問題

Question

我有以下線程接受特定端口的傳入連接：

public class ClientThread implements Runnable {
    ServerSocket serverSocket;
    Socket clientSocket;
    int serverPort = 6500;
    private String serverIpAddress = "127.0.0.1";
    DataInputStream is;
    ObjectOutputStream os=null;
    Coordinate coord;

    protected BlockingQueue queue = null;

    public ClientThread(BlockingQueue queue) {
        this.queue = queue;
    }

    public void run() {
        try {
            InetSocketAddress serverAddr = new InetSocketAddress(
                    serverIpAddress, serverPort);
            serverSocket = new ServerSocket();
            serverSocket.bind(serverAddr);
            System.out.println("s-a creat");
        } catch (UnknownHostException e) {
            System.err.println("Don't know about host");
        } catch (IOException e) {
            System.err.println("Couldn't get I/O for the connection to host");
        }

        try {
            clientSocket = serverSocket.accept();
            System.out.println("S-a conectat clientul de monitorizare!");

            os=new ObjectOutputStream(clientSocket.getOutputStream());
            try{
                while(true){
                    coord=(Coordinate)queue.take();
                    System.out.println(coord.getLat()+coord.getLon()+coord.getwId());
                    os.writeObject(coord);
                    os.flush();
                }
            } catch(Exception e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            System.out.println(e);

            try {
                clientSocket.close();
                os.close();
            }catch(Exception e1) {
                e1.printStackTrace();
            }
        }
    }
}

我要發送的 object 是以下 class 的一個實例：

public class Coordinate implements Serializable{
    private final int lon;
    private final int lat;
    private final int workerId;

    public Coordinate(int lat, int lon, int workerId) {
        this.lat = lat;
        this.lon = lon;
        this.workerId=workerId;
    }

    public int getLon() {
        return lon;
    }

    public int getLat() {
        return lat;
    }

    public int getwId() {
        return workerId;
    }
}

但是當我啟動線程並接受連接時，我收到以下錯誤：

java.net.SocketException: Software caused connection abort: socket write error
    at java.net.SocketOutputStream.socketWrite0(Native Method)
    at java.net.SocketOutputStream.socketWrite(Unknown Source)
    at java.net.SocketOutputStream.write(Unknown Source)
    at java.io.ObjectOutputStream$BlockDataOutputStream.drain(Unknown Source)

    at java.io.ObjectOutputStream.writeObject(Unknown Source)
    at servers.ClientThread.run(ClientThread.java:55)
    at java.lang.Thread.run(Unknown Source)

有人知道出了什么問題嗎？

這個錯誤java.net.SocketException：軟件導致連接中止出現在一個套接字端崩潰時......在我的情況下是連接到ClientThread（）的端並且當我試圖在緩沖區中寫入時出現錯誤。

您沒有放置客戶端代碼，很難理解客戶端可以做什么，但我看到代碼的一部分可能存在問題。 這是

 while(true){
                    coord=(Coordinate)queue.take();
                    System.out.println(coord.getLat()+coord.getLon()+coord.getwId());
                    os.writeObject(coord);
                    os.flush();
                }

java.net.SocketException: Software caused connection abort: socket write error是什么意思？ 這意味着連接已關閉但您嘗試將一些數據寫入套接字。 但我可能是錯的。
