同时将多个客户端连接到java服务器时发生套接字写入错误

我正在创建一个桌面应用程序，其中多个客户端必须使用它们之间的套接字连接连接到服务器。我成功地连接了它们，但当我同时将多个客户端连接到服务器时，出现了问题，服务器出现错误“套接字写入错误” 我的代码在下面，请给我一个答案

public class SocketConnection implements Runnable {
    // password of oracle database

    ServerSocket serverSocket = null;
    Socket socket = null;
    DataInputStream dataInputStream = null;
    DataOutputStream dataOutputStream = null;
    Socket clientSocket = null;
    DBConnection dbConnection;


    public SocketConnection() {
        // TODO Auto-generated constructor stub

        dbConnection = new DBConnection();

        if (con != null) {

            serverSocket = dbConnection.createSocket();

            if (serverSocket != null) {

                System.out.println("Server Started. Looking for the connections.");
                System.out.println("Listening Port:8888.......");
            }



            Thread t = new Thread(this);
            t.start();
        }

    }


    @Override
    public void run() {
        // TODO Auto-generated method stub
        while (true) {
            try {
                clientSocket = serverSocket.accept();
                System.out.println("Connection Accepted");
                Connect m_connect = new Connect(clientSocket);

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }

你为什么用这种低级的方式做这件事？选择一个记录良好的API并通过它进行通信

您是否已经阅读过这样的文章：

您知道哪一行抛出了该错误吗？我在读写操作中遇到了错误。代码中的哪个读写操作抛出了该错误？很明显，这是一个读/写操作，因为它在错误消息的标题中。。java.net.SocketException:软件导致的连接中止：java.net.SocketOutputStream.socketWrite0（本机方法）处的套接字写入错误，java.net.SocketOutputStream.socketWrite（未知源）处的java.net.SocketOutputStream.write（未知源）处的java.io.DataOutputStream.write（未知源）处的java.io.DataOutputStream.writef处的套接字写入（未知源）连接Oracle$SocketConnection$Connect.run（ConnectOracle.java:529）的java.io.DataOutputStream.writeUTF（未知源）n第529行是..DataOutputStream.writeUTF（res2.getString（t））；in pass=1；我不知道..如何实现这一点我很抱歉，但我不能教你开发协议。为什么你不使用RMI或其他？然后你可以发送愚蠢的简单POJO来表示你的命令并返回一些数据。但是我永远不会实现这一点，不管你尝试什么，由我自己来考虑。！！但我的问题现在已经解决了我也试着去学。。
