Do we really need a second property ?
Can't we just look for "mp.messaging.connector.vertx.identifier" and if it is defined look up the instance with it?

+1, just the identifier value should be fine.

Maybe not using Identifier, I will test to confirm that. The case it tries to cover is when there is a vertx instance exposed with a cdi qualifier(Named("vertx")) but the Instance<Vertx> ist in the ExecutionHolder, the ist.isUnsatisfied() is false, which forces sr rm to inject the instance.
BTW, I will be on holidays this week, will report back next week, thanks :)

Done by using only the first option and the @io.smallrye.common.annotation.Identifier qualifier only.
The vertx bean from the vertx subsystem is exposed with 2 qualifiers: @Any and @Identifier, so to select the instance only when the cdi qualifier is specified, I split the @Default out in the else check block.

@ozangunalp thank you for the reviews, I updated to add a test in the provider module, please let me know if there is anything needs to be fixed or improved. :) |
Fixes #2771
This PR tries to add 2 config items:
mp.messaging.connector.vertx.cdi.qualifier, which is used to tries to inject the Vertx instance with the specified qualifier if configured.mp.messaging.connector.vertx.cdi.qualifier.required, boolean, which is used to indicate if the qualifier is required in case it comes from CDI, otherwise it will create a new Vertx instance like what current does.ExecutionHolderis used by both WildFly and Quarkus. And for WildFly, there is a coming vertx subsystem to be able to configure the VertxOptions following the WildFly management model style, which will expose a CDI bean with a qualifier so that other subsystems can select it by themselves. The 2nd config item can be included in the integration code of WildFly so that applications deployed to WildFly will inject only the instance with a qualifier, and leave the use case in Quarkus not changed at all.
