How to exclude a @Repository from component scan when using Spring Data Rest

Question

in a spring boot project I have problems to exclude some repositories from the component scan.

I have a library that contains some entities and some repositories (JpaRepositories). For some reason I implemented a small Spring Boot Data Rest application that shall be used to give testers a quick access to the entities. Therefore I implemented a repository that extends the PagingAndSortingRepository and is annotated with @RepositoryRestResource.

When the application starts all repository will be scanned and made available. As long as I only want to have the Data Rest repositories available I annotated the componenten scanner to exclude the unwant repositories. But this doesn't work. I checked with the actuator beans endpoint and whatever I do - no repositories are excluded.

To demonstrate the problem I created a simple demo application: https://github.com/magomi/springboot-restdata-repoloading.

To exclude the DataRepository I tried the two approaches:

// exclude V02
@SpringBootApplication
@ComponentScan(excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {
                DataRepository.class})
})

and

// exclude V01
@SpringBootApplication(exclude = { DataRepository.class })

Without success. When I call the /beans endpoint (provided by spring boot actuator) I always see

{
    bean: "dataRepository",
    aliases: [ ],
    scope: "singleton",
    type: "org.codefromhell.test.repoloading.DataRepository",
    ...
},
{
    bean: "dataApiRepository",
    aliases: [ ],
    scope: "singleton",
    type: "org.codefromhell.test.repoloading.api.DataApiRepository",
    ...
},

Because it's a repository and not strictly a @Component, you need to excluded it by adding @EnableJpaRepositories to your application:

@SpringBootApplication
@EnableJpaRepositories(excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {
                DataRepository.class})
})
public class ApiApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApiApplication.class, args);
    }
}
