Java Socket 连接后关闭？

Question

为什么在客户端建立连接后此端口/套接字会关闭？

package app;

import java.io.*;
import java.net.*;

public class socketServer {

public static void main(String[] args) {
    int port = 3333;
    boolean socketBindedToPort = false;

    try {
        ServerSocket ServerSocketPort = new ServerSocket(port);
        System.out.println("SocketServer Set Up on Port: " + port);
        socketBindedToPort = true;

        if(socketBindedToPort == true) {
            Socket clientSocket = null;

            try {
                clientSocket = ServerSocketPort.accept();//This method blocks until a socket connection has been made to this port.
                System.out.println("Waiting for client connection on port:" + port);
                /** THE CLIENT HAS MADE A CONNECTION **/
                System.out.println("CLIENT IS CONENCTED");
            } 
            catch (IOException e) {
                System.out.println("Accept failed: " + port);
                System.exit(-1);
            }
        }
        else {
            System.out.println("Socket did not bind to the port:" + port);
        }
    }
    catch(IOException e) {
        System.out.println("Could not listen on port: " + port);
        System.exit(-1);
    }



}


}

未经测试，但我很确定这是因为你的程序中没有剩下任何东西。一旦 ServerSocketPort.accept();完成后，程序到达 main 的末尾并关闭。
