Java多线程Web服务器-无法接收多个GET请求 [英] Java Multithreaded Web Server - Not recieving multiple GET requests

问题描述

我有一个非常基础的多用途Web服务器的启动，只要一次收到一个GET请求，它就可以接收所有GET请求.

I have the starts of a very basic multi-hreaded web server, it can recieve all GET requests as long as they come one at a time.

但是，当同时收到多个GET请求时，有时会全部收到，而有时却丢失了一些.

However, when multiple GET requests come in at the same time, sometimes they all are recieved, and other times, some are missing.

我通过创建一个带有多个指向我的网络服务器的图像标签的html页面并在firefox中打开该页面来进行了测试.我总是使用shift + refresh.

I tested this by creating a html page with multiple image tags pointing to my webserver and opening the page in firefox. I always use shift+refresh.

这是我的代码，我必须做的是根本上错误的事情.

Here is my code, I must be doing something fundamentally wrong.

public final class WebServer
{
    public static void main(String argv[]) throws Exception
    {
        int port = 6789;

        ServerSocket serverSocket = null;
        try
        {
            serverSocket = new ServerSocket(port);
        }
        catch(IOException e)
        {
            System.err.println("Could not listen on port: " + port);
            System.exit(1);
        }

        while(true)
        {
            try
            {
                Socket clientSocket = serverSocket.accept();
                new Thread(new ServerThread(clientSocket)).start();
            }
            catch(IOException e)
            {

            }
        }
    }
}

public class ServerThread implements Runnable
{
    static Socket clientSocket = null;

    public ServerThread(Socket clientSocket)
    {
        this.clientSocket = clientSocket;
    }

    public void run()
    {
        String headerline = null;
        DataOutputStream out = null;
        BufferedReader in = null;

        int i;

        try
        {
            out = new DataOutputStream(clientSocket.getOutputStream());
            in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

            while((headerline = in.readLine()).length() != 0)
            {
                System.out.println(headerline);
            }
        }
        catch(Exception e)
        {

        }
}

推荐答案

我实际上发现了问题所在:

I actually discovered the problem was this:

  static Socket clientSocket = null;

一旦我移除了静电，它现在就可以正常工作了.

Once I removed the static, it works perfectly now.
