SpringBoot Spring May Create An ApplicationListener with Class Annotated With @Component Twice

Firstly, I define my ApplicationListener in META-INF/spring.factories as folllows: Secondly, I annotate the ApplicationListener with Annotation @Component as follows: Thirdly, When I run my application, I get the following results: the output result shows that MyListener has been created twice, which has different reference, which results in this listener is called twice. Is this the expected result? Why a class annotated with @Component can still be instaniated twice. spring boot version: 2.5.2 my sample code : bug-test.zip

Yes it is the expected behavior. You are registering two components really, one using spring.factories and one by using classpath scanning and flagging the class as being a component.
