@Inject Injection into EntityListener not working #6948
Description
Describe the bug
I do have JPA entities annotated with @EntityListeners.
I @Inject some CDI bean (@RequestScoped in my case but happens for other scopes, too) into the EntityListener.
The bean never gets injected, the reference is allways null.
Things I tried:
- placing some CDI scope annotation onto the entity listener.
- Tried different CDI scopes on the injected bean
- Tried all variants of injection: constructor-, setter- and attribute-injection on the listener
Expected behavior
Instance of the CDI bean should get injected
Actual behavior
The CDI bean reference is allways null resulting in a NPE when accessing some attribute of the bean.
To Reproduce
See attached test case
Configuration
quarkus.datasource.url=jdbc:h2:tcp://localhost/mem:test
quarkus.datasource.driver=org.h2.Driver
quarkus.hibernate-orm.database.generation=drop-and-create(Also happens with postgresql, drop-and-create is just for testing)
Environment (please complete the following information):
- Output of
java -version: from 8 to 11 - Quarkus version or git rev: 1.2.0
Additional context
Interestingly, when the CDI bean I want injected into the EntityListener ist injected somewhere else (e.g. some @ApplicationScoped bean), injection works.
Possible causse: looks like Quarkus bean discovery does not regard EntityListeners as trigger for registering some bean during compile-time-initialization.
