save uploaded file to filesystem

[Susan Lin]

Looking at https://github.com/vert-x3/vertx-examples/blob/master/web-examples/src/main/java/io/vertx/example/web/upload/Server.java how do I save the file uploaded to the servers filesystem?

package io.vertx.example.web.upload;
	import io.vertx.core.AbstractVerticle;
	import io.vertx.example.util.Runner;
	import io.vertx.ext.web.FileUpload;
	import io.vertx.ext.web.Router;
	import io.vertx.ext.web.handler.BodyHandler;
	/*
	* @author <a href="http://tfox.org">Tim Fox</a>
	*/
	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());
	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);
	}
	}

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());

}

the FileUpload object is saved in a temp directory you can either keep it there or pump it somewhere else on the filesystem:
