Add setter for order for DefaultSimpUserRegistry [SPR-17023]

[spring-projects-issues]

Filip Hrisafov opened SPR-17023 and commented

Currently the DefaultSimpUserRegistry and MultiServerUserRegistry are using the Ordered.LOWEST_PRECEDENCE.

We have listeners that are listening on SessionConnectedEvent and in some of our logic we are checking the SimpUserRegistry. However, if our listener is triggered before the registry ones then there is no user in the registry (if this is the first connection).

I currently managed to register my listener after the registry ones. However, I am not sure that this is deterministic enough. I just annotated it with @Order

We could add a setOrder on DefaultSimpUserRegistry for starters. Are you using WebSocketMessageBrokerConfigurer or extending from WebSocketMessageBrokerConfigurationSupport?

Having a setOrder might work for us. We are using the WebSocketMessageBrokerConfigurer. We are actually providing a library and users need to enable it through @EnableWebSocketMessageBroker. We have a small Spring Boot auto configuration to configure the broker actually.

I've added setOrder on DefaultSimpUserRegistry that is also picked up by MultiServerUserRegistry. I'll stop here since I'm not familiar with the details of your setup, let me know if you need anything further.

Thanks a lot Rossen. I think that this should be enough. It is a bit "difficult" to set the order (would need to either do provide our own WebSocketMessageBrokerConfigurationSupport, which I would like to avoid). However, I can probably do it with a BeanPostProcessor as well.

We are using Spring Boot, so I will try to do some more general auto configuration that can be used perhaps. Do you know if there are some plans to have Boot auto configurations for this components from Spring?

Okay, in that case I can expose something on MessageBrokerRegistry. Since this ticket is already closed and released, please create a separate ticket for that, and I'll mark it for 5.1 RC2.

Filip Hrisafov regarding your question about Boot plans for auto config, you might want to add a comment under spring-projects/spring-boot#65. It was closed recently due to lack of activity but nevertheless it's the best place to leave some record.

Thanks a lot for everything Rossen. I just created #21679 for the setter. I will comment on the Boot issue as well.
