Add Bean Name Alias for Beans with Generated Names [INT-2417]

[spring-operator]

Gary Russell opened INT-2417 and commented

Parsers generate bean names for handlers within consuming endpoints, e.g.

org.springframework.integration.handler.LoggingHandler#0

It would be useful if these beans could have aliases (e.g. endpoint.handler) so a reference to the handler could be easily obtained from the context.

If we can ensure uniqueness, we could even replace the generated name with our own more meaningful names, right?

Gary Russell commented

Right, the uniqueness would be maintained by using the endpoint id as a prefix (like the way we do with channel.adapter) but I figured we could keep the generated name in case someone is already using it.

It's brittle, because the parse order matters, but it is possible someone might have, say, one instance of a handler and @Autowire it with a @Qualifier, or get it by name from the context.

Sure, I guess it doesn't hurt. Maybe for 3.0 we could consider removing the generated names altogether.
