public class Server extends AbstractVerticle {

  // Convenience method so you can run it in your IDE
  public static void main(String[] args) {
    Runner.runExample(Server.class);
  }

  @Override
  public void start() throws Exception {

    Router router = Router.router(vertx);

    // Enable multipart form data parsing
    router.route().handler(BodyHandler.create().setUploadsDirectory(System.getProperty("java.io.tmpdir")));

    router.route("/").handler(routingContext -> {
      routingContext.response().putHeader("content-type", "text/html").end(
        "<form action="/form" method="post" enctype="multipart/form-data">n" +
          "    <div>n" +
          "        <label for="name">Select a file:</label>n" +
          "        <input type="file" name="file" />n" +
          "    </div>n" +
          "    <div class="button">n" +
          "        <button type="submit">Send</button>n" +
          "    </div>" +
          "</form>"
      );
    });

    // handle the form
    router.post("/form").handler(ctx -> {
      ctx.response().putHeader("Content-Type", "text/plain");

      ctx.response().setChunked(true);

      for (FileUpload f : ctx.fileUploads()) {
        System.out.println("f");
        ctx.response().write("Filename: " + f.fileName());
        ctx.response().write("n");
        ctx.response().write("Size: " + f.size());
      }

      ctx.response().end();
    });

    vertx.createHttpServer().requestHandler(router::accept).listen(8080);
  }
}

您可以使用vertx-web轻松处理文件上传：

router.route().handler(BodyHandler.create());

router.post("/some/path/uploads").handler(routingContext -> {

    Set<FileUpload> uploads = routingContext.fileUploads();
    // Do something with uploads....
});

而且，您将利用路由功能，甚至可以提供诸如index.html之类的静态文件。
