请教，ObjectOutputStream写入到网络中报错！

Question

我使用ObjectOutputStream从客户端写入对象到网络中，在服务器端读取对象，
然后保存到文件中。但是当我把对象写入到网络中时，出现异常。
client.java

 public class Client<M> {

    public void add(M m) {//向远程网络中存储对象
        Socket socket;
        ObjectOutputStream oos = null;
        try {
            try{
                socket = new Socket("127.0.0.1", 8011);
                OutputStream os = socket.getOutputStream();
                oos = new ObjectOutputStream(os);
                oos.writeObject(m);
                oos.flush();
            }finally {
                if(oos!=null){
                    oos.close();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }

}

Server.java

 public class Server {
    public static void main(String[] args) {
        new Server().startServer();
    }
    public void startServer(){
        ServerSocket ss;
        ServerThread st;
        try {
            ss = new ServerSocket(8011);
            while(true){
                System.out.println("服务已经开启");
                Socket socket = ss.accept();
                st = new ServerThread(socket);//创建线程对象
                ExecutorService es = Executors.newCachedThreadPool();
                es.execute(st); //开启线程
                es.shutdown();
                socket.close();//关闭socket
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

线程
ServerThread.java

 public class ServerThread implements Runnable{
    private Socket socket;
    //private ObjectOutputStream oos = new ObjectOutputStream();
    private FileOutputStream fos;
    private ObjectInputStream ois;
    public ServerThread(Socket socket) {
        this.socket = socket;
    }
    @Override
    public void run() {
        try {
            InputStream is = socket.getInputStream();
            ois = new ObjectInputStream(is);
            Object obj = ois.readObject();//读取网络中的对象

            System.out.println(obj);
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            try {
                if(ois!=null)
                    ois.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

错误如下：

 通过客户端向服务器写入对象
java.net.SocketException: Software caused connection abort: socket write error

希望同志们能给予我解答，十分感谢！！！！

在你的server这个类中 你主动关闭了socket 导致socket is colsed
