To show the non-blocking characteristics of Vertx I would like to simulate a long-running request.
I am wondering if the following code is correct:
public class Server extends Verticle {
HttpServerRequest _req;
public void start() {
vertx.createHttpServer().requestHandler(new Handler<HttpServerRequest>() {
public void handle(HttpServerRequest req) {
System.out.println("Got request: " + req.uri);
System.out.println("Headers are: ");
for (String key : req.headers().keySet()) {
System.out.println(key + ":" + req.headers().get(key));
}
_req = req;
vertx.setTimer(5000, new Handler<Long>() {
@Override
public void handle(Long timerId) {
_req.response.headers().put("Content-Type", "text/html; charset=UTF-8");
_req.response.end("<html><body><h1>Hello from vert.x!</h1></body></html>");
}
});
}
}).listen(8080);
}
Is this the correct way to pass the request into the handler? I guess it is not... but how can I pass the request into the handler?

variable _req. Just make req final and you will be able to access it in
your handler.
