What is the problem with the creation of Spring bean?

go to my code first

@Component
@Slf4j
public class CSPDJournalListTask {
    @Autowired
    ArticleEntityRepository articleEntityRepository;

    @Async
    public void task2(){
        List<ArticleEntity> list = articleEntityRepository.findAll();
        System.out.println(list.toString());

    }

}

above is an asynchronous task created using SpringBoot, and @ EnableAsync comments have been added

next, I created a simple unit test as follows:

@RunWith(SpringRunner.class)
@SpringBootTest
public class CSPDJournalListProcessorTest {


    @Autowired
    CSPDJournalListTask cspdJournalListTask;

    @Test
    public void test() {
        cspdJournalListTask.task();
    }

}

then something strange happens, throwing the following exception

org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name "inMemoryDatabaseShutdownExecutor": Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

focus on this sentence:

Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

seems to say that the single instance bean I am using has been closed. Is it because of this async?

what should I do if I need to do this in an asynchronous task?

I hope the gods will see the answer. Thank you very much!
