I’m trying to do some learning with Project Reactor in Java, and am getting a little hung up on using the subscribe()
method on a Flux
. Here’s a small example:
Flux.range(1, 3)
.subscribeOn(Schedulers.boundedElastic())
.subscribe(i -> System.out.println("Looking at: " + i));
System.out.println("All done!");
Which gives me the following output:
All done!
Looking at: 1
Looking at: 2
Looking at: 3
The behavior I’m looking to see would be to have the "All done!" message print after the "Looking at" messages. I can get there by removing the subscribeOn
call, but I’m looking to have the method within the subscribe
call executed asynchronously (obviously the println
is contrived for this example). Is there a way that I could "block" until the Flux
I’ve subscribed to has completed? Is there some way that I could go to a Mono<Void>
or something?
