服务器端readutf的EOF异常

Question

我正在开发一个客户端服务器套接字应用程序。在运行（覆盖）方法中为多个客户端读取服务器端的字符串，并在readUTF获取EOF异常。我不知道为什么会出现错误以及如何纠正错误。

    while (ss.compareTo("true") == 0) {
        System.out.println("Waiting for port " + port);
        sdc = soc.accept();

        cs[i] = sdc;
        System.out.println("Connected port " + cs[i]);

        DataInputStream dind = new DataInputStream(cs[i].getInputStream());
        DataOutputStream dout = new DataOutputStream(cs[i].getOutputStream());

        String password = dind.readUTF();
        String dept = dind.readUTF();
        uniqueName = dind.readUTF();
        String username = dind.readUTF();
        String ipaddress = dind.readUTF();
        String macaddress = dind.readUTF();
        String groupname = dind.readUTF();
    }
