Access CDI beans from BeanStep route handler for Quarkus extension

[jfbenckhuijsen]

Hi,

I'm currently working on a PR for the quarkus google cloud extension (ref: quarkiverse/quarkus-google-cloud-services#776 ) together with @loicmathieu .

What I want to achieve is register a specific endpoint (conditionally, if the config is enabled) to handle push messages. Given the docs at https://quarkus.io/guides/writing-extensions#extension-defined-endpoints I see I can register a custom handler which should be sufficient for what I want to achieve.

However, from the handler (the MyCustomHandler I need to access a CDI bean which is defined in the -runtime module of my extension (the CDI bean holds the various listeners for messages as registered by the user).

What is the correct way to access CDI beans from that handler (which is not a CDI bean itself)? Just use CDI.current().select(...) or is there another way to achieve this?

CDI.current() or Arc.container() is probably the best option if the caller is not a CDI bean.

Arc.container() is the idiomatic way in Quarkus, giving you access to various Quarkus-only features on top (such as listAll methods if you need those).
