Custom implementation in @RepositoryRestResource

I'm working on a spring-boot project which uses @RepositoryRestResource.

There are 2 entities, Product & Domain, which has many-to-many relation.

I want to implement a custom REST call which is running a complex query.

To implement custom implementation I'm following this blog.

ProductRepository Interface:

@RepositoryRestResource(collectionResourceRel = "product", path = "product")
public interface ProductRepository extends CrudRepository<Product, Long>, CustomProductRepository {

    List<Product> findByName(@Param("name") String name);

}

CustomProductRepository.java - Interface for custom REST call

public interface CustomProductRepository {
    public List<Product> findByDomainName(String domainName);
}

ProductRepositoryImpl.java - It's implementation. (I'm following the naming convention as mentioned in the blog)

public class ProductRepositoryImpl implements CustomProductRepository {

    @Override
    public List<Product> findByDomainName(long id, String domainName) {
        List<Product> result = new ArrayList<>();
        // Query logic goes here
        return result;
    }
}

Updating ProductRepository.java to extend CustomProductRepository

@RepositoryRestResource(collectionResourceRel = "product", path = "product")
public interface ProductRepository extends CrudRepository<Product, Long>, CustomProductRepository {

    List<Product> findByName(@Param("name") String name);

}

The application starts without error. I expect when I call http://localhost:8080/product/search, it should list my custom method: findByDomainName. But it doesn't.

All I get is:

{
  "_links" : {
    "findByName" : {
      "href" : "http://localhost:8080/product/search/findByName{?name}",
      "templated" : true
    },
    "self" : {
      "href" : "http://localhost:8080/product/search/"
    }
  }
}

Even when I call make a REST call to http://localhost:8080/product/search/findByDomainName, I get 404.

What am I missing?

Thanks.

Apparently it is not possible by design. The custom method would work though, if annotated with @Query. See implementing-custom-methods-of-spring-data-repository-and-exposing-them...
