Java实现一个简易HTTP服务器 (二) -- 多线程

运行方法:新建项目后在目录下创建index.html.

favicon为可选项,作为网站图标

public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(80);
        System.out.println("Server started at " + new Date() + "\n");
        try {

        } catch (Exception e) {
            e.printStackTrace();
            serverSocket.close();
        }
    }
