QUESTION
Just starting to understand reactive programming with Reactor and I've come across this code snippet from a tutorial here building-a-chat-application-with-angular-and-spring-reactive-websocket
...ANSWER
Answered 2021-May-20 at 13:21The difference is much more conventional rather than functional - the difference being side-effects vs a final consumer.
The doOnXXX series of methods are meant for user-designed side-effects as the reactive chain executes - logging being the most normal of these, but you may also have metrics, analytics, etc. that require a view into each element as it passes through. The key with all of these is that it doesn't make much sense to have any of these as a final consumer (such as the println() in your above example.)
On the contrary, the subscribe() consumers are meant to be a "final consumer", and usually called by your framework (such as Webflux) rather than by user code - so this case is a bit of an exception to that rule. In this case they're actively passing the messages in this reactive chain to another sink for further processing - so it doesn't make much sense to have this as a "side-effect" style method, as you wouldn't want the Flux to continue beyond this point.
(Addendum: As said above, the normal approach with reactor / Webflux is to let Webflux handle the subscription, which isn't what's happening here. I haven't looked in detail to see if there's a more sensible way to achieve this without a user subscription, but in my experience there usually is, and calling subscribe manually is usually a bit of a code smell as a result. You should certainly avoid it in your own code wherever you can.)
QUESTION
I have an existing spring web application that uses spring-boot-starter-web; I have been planning to introduce reactive into this application. For a new feature that I am working, I have pulled in spring reactive web socket, configured and coded as specified in the spring doc; but unfortunately it does not work (got 404). I tried a sample application and that works perfectly. I used this one as my sample application.
I found that the sample application comes up on Netty, not on Tomcat. So I added spring-boot-starter-web to it, got the server to start in Tomcat and got the same 404 as I got in my application. I also added TomcatRequestUpgradeStrategy unsuccessfully.
should I assume that spring-web and spring-webflux conflict with each other and I should go back to the regular websocket? Please advise.
...ANSWER
Answered 2020-Sep-12 at 11:20Spring said that if both spring web and spring webflux present in the classpath; spring web kicks in and reactive websocket won't come up. More details here: https://github.com/spring-projects/spring-boot/issues/23236
QUESTION
I'm trying to solve this: How to rewrite URLs with Spring (Boot) via REST Controllers? by creating some kind of "filter" which would be applied to every incoming HTTP request.
The matter is covered by some answers like for this question: Spring Boot Adding Http Request Interceptors
but interface HandlerInterceptor deals with javax' HttpServletRequest and HttpServletResponse which are not as practical as the new class introduced by Spring i.e. the ServerWebExchange (see the use of setLocation() in the code below) which appears in an interface whose name sounds promising, org.springframework.web.server.WebFilter:
So I ended with something like:
...ANSWER
Answered 2020-Sep-07 at 15:44I fact, I didn't make work WebFilter in a non-WebFlux context, but I could successfully implement such a filter, which both implements javax.servlet.Filter (non-reactive) AND org.springframework.web.server.WebFilter (reactive).
Here is my answer to the other related question: https://stackoverflow.com/a/63780659/666414
QUESTION
I have a spring boot rsocket implementation where if a client cancels or closes their rsocket request then I want to cancel other subscription registrations on the server.
In the logs on the spring boot server I can see that a cancel message is sent or received:
...ANSWER
Answered 2020-Apr-30 at 12:11To capture the cancel signal you can use subscribe to onClose() event.
In your controller
QUESTION
ANSWER
Answered 2020-Mar-17 at 05:05I have implemented sample code to help you with this. You will need to clean this up and adapt to your needs, but I have tested this and it does work.
The first step is to implement an Encoder where is the type of the object you want to encode. In my example I am using JsonNode.
