Imports
com.sun.net.httpserver.HttpServer, .SimpleFileServer, .SimpleFileServer.OutputLevel, java.io.IOException, .PrintWriter, java.net.Inet6Address, .InetAddress, .InetSocketAddress, .UnknownHostException, java.nio.file.Files, .Path, java.util.Arrays, .Iterator, .Locale, .NoSuchElementException, .Objects
A class that provides a simple HTTP file server to serve the content of a given directory.

The server is an HttpServer bound to a given address. It comes with an HttpHandler that serves files from a given directory path (and its subdirectories) on the default file system, and an optional Filter that prints log messages related to the exchanges handled by the server to a given output stream.

Unless specified as arguments, the default values are:

  • port: 8000

    • The implementation is provided via the main entry point of the jdk.httpserver module.
