Can't Find A Reponsitory

Question

I have a repository interface as

@Repository
public interface WordRepository extends ReactiveCrudRepository<Word, Long> {}

And in the @SpringApplication class, I have

@Bean
ApplicationListener<applicationReadyEvent> ready(WordRepository rep) {
   ...
}

to populate some data to the database. It won't be compiled. After the message "APPLICATION FAILED TO START", it says

Action:

Consider defining a bean of type 'com.example.reactive.wordservice.WordRepository' in your configuration.

With or without the annotation @Repository won't yield a different outcome. I change to another approach with a new class instead.

@Component
class WordDataInitializer {

  private static Logger log = LoggerFactory.getLogger(WordDataInitializer.class);

  private WordRepository wordRepository;

  public WordDataInitializer(WordRepository wordRepository) {
    this.wordRepository = wordRepository;
  }

   @EventListener(ApplicationReadyEvent.class)
   public void initializeDB() throws URISyntaxException, IOException {
    ...
   }
}

The outcome is still the same. I have done that many times and don't know why it doesn't work this time with Reactor. The Spring Boot is the latest version, 2.3.0 release.

What is missing?

Looks like the component scan is configured incorectly. But for deeper analyzation we need atleast the package structure. — Jens, May 26 '20 at 05:33
@Jens you are absolutely right. I will post detail in my own answer. — vic, May 26 '20 at 17:40

After waking up this morning, I recognized that a dependency I added might cause the problem. I added the Spring Boot starter data JPA to get the @Entity annotation. Removing the dependency solves the problem.

The Reactive DB works differently. The Entity is one case. Also, a schema.sql file won't get picked up automatically as the JPA approach does. I need to write some code to pick up the schema file.
