Configuration using annotation @SpringBootApplication

I have problem with Spring Boot configuration.

And I have a problem, configuration works only for classes in sub catalog:

I have tried annotation @ComponentScan but it didn't help.

Do You have any idea what can I do with this?


The Spring Boot documentation for @SpringBootApplication states

Many Spring Boot developers always have their main class annotated with @Configuration, @EnableAutoConfiguration and @ComponentScan. Since these annotations are so frequently used together (especially if you follow the best practices above), Spring Boot provides a convenient @SpringBootApplication alternative.

The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration and @ComponentScan with their default attributes: [...]

where the @ComponentScan javadoc states

If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.

That is, only the types that are in the same package as your ReadingListApplication will be scanned.

If you want a custom configuration, provide your own @Configuration, @EnableAutoConfiguration, and @ComponentScan, as appropriate.
