Environment: Spring Boot 2.2.0.RELEASE, Axon 4.2, Kotlin 1.3.40
I’m trying to inject a logger into my @EventHandler class.
The logger is built as a spring bean like this:
@Bean
@Scope(“prototype”)
open fun buildLogger(ip: InjectionPoint): KLogger {
// Build the logger…
}
At first I tried injecting it as a constructor parameter in my class:
@Component
open class TestProjection(@Autowired val logger: KLogger) {}
Using the debugger I can see that the logger is created successfully during application startup, but when the @EventHandler method is invoked the logger field is null…
Changing approach, I tried injecting the logger into the event handler method:
@EventHandler
fun on(event: SystemCreatedEvent, logger: KLogger) {
// Event handler logic…
}
When I do method level injection I instead get the following error from Axon/Spring:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘testProjection’ defined in file [***com/tmp/TestProjection.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘buildLogger’ defined in class path resource [com/tmp/TestConfiguration.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalStateException: No current InjectionPoint available for method ‘buildLogger’ parameter 0

Does anyone have any ideas on how to resolve this issue?
