Question

我有一个Web应用程序JSF，它充当客户端，另一个Java应用程序充当服务器。现在我有一个startEngine（）函数，它启动服务器上的应用程序，并且工作正常。我还有另一个名为addWebSite的函数，它假设将一个网站添加到之前打开的同一个应用程序中。我对服务器的第一次调用有效，但第二次调用没有，我想在服务器上调用更多函数。

这是我的startEngine函数和addWebSite函数。注意：这是一个管理的大豆会话，但这不会影响任何事情

public void startEgineNow() throws UnknownHostException, IOException {
        Session session = HibernateUtil.getSession();


    try {
        session.beginTransaction();
        // get student from database
        IPAddress myAddress = session.get(IPAddress.class, sendToSocketId);
        session.getTransaction().commit();

        if (myAddress.getIpAddress() != null) {
            clientSocket = new Socket(myAddress.getIpAddress(), myAddress.getPortNumber());


            PrintWriter out =
                    new PrintWriter(clientSocket.getOutputStream(), true);

                BufferedReader in =
                    new BufferedReader(
                        new InputStreamReader(clientSocket.getInputStream()));

                out.println("startEngine");
                out.flush();
                out.close();
            }
        } finally {
        if (session != null) {
            session.close();
        }

    }       
}

public void addWebsite() throws UnknownHostException, IOException{
    Session session = HibernateUtil.getSession();

    System.out.println(sendToSocketId);
        try {
            session.beginTransaction();
            // get student from database
            IPAddress myAddress = session.get(IPAddress.class, sendToSocketId);

             Sites sites = new Sites(addSite);
             sites.setAddress(myAddress);

             session.persist(sites);


             session.getTransaction().commit();


             if (myAddress.getIpAddress() != null) {
                    clientSocket = new Socket(myAddress.getIpAddress(), myAddress.getPortNumber());


                    PrintWriter out =
                            new PrintWriter(clientSocket.getOutputStream(), true);

                        BufferedReader in =
                            new BufferedReader(
                                new InputStreamReader(clientSocket.getInputStream()));

                        out.println("addWebSite");
                        out.flush();
                        out.close();
                }


            } finally {
            if (session != null) {
                session.close();
            }

            }       
}

这是我的服务器端代码

public static void main(String[] args) throws InterruptedException, NumberFormatException, IOException {

    MainListener myListener = new MainListener();

    ServerSocket serverSocket =
            new ServerSocket(5000);
        Socket clientSocket = serverSocket.accept();     
        PrintWriter out =
            new PrintWriter(clientSocket.getOutputStream(), true);                   
        BufferedReader in = new BufferedReader(
            new InputStreamReader(clientSocket.getInputStream()));

        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            if (inputLine.equals("startEngine")) {
                myListener.runDesktop();

            }else if(inputLine.equals("addWebSite")){
                myListener.addWebsite("https://www.buzzfeed.com/");
            }
        }

当我使用startEngine方法启动引擎时，我希望服务器对其他调用保持打开状态。只有当我从客户端发送close（）函数时才关闭，请问我在这里做错了什么
