Java 18开发者新特性详解：简易Web服务器、代码片段标注与UTF-8默认编码

$ jwebserver -b 0.0.0.0 -p 8000

import java.net.InetSocketAddress;
import java.nio.file.Path;
import com.sun.net.httpserver.SimpleFileServer;
import static com.sun.net.httpserver.SimpleFileServer.OutputLevel;

public class App {
  public static void main(String[] args) {
    var server = SimpleFileServer.createFileServer(
      new InetSocketAddress(8000), 
      Path.of("/home/java"), 
      OutputLevel.VERBOSE);
    server.start();
    System.out.println("Server started on port 8000");
  }
}
