Tip: How to Selectively Expose CRUD Operations

See how to use an intermediate interface to expose CRUD operations.


advertisement

In order to selectively expose CRUD operations, we need to define an intermediate interface, annotated as below:

@NoRepositoryBean
interface IntermediateRepository extends Repository {

   //  add here the selected CRUD, for example we add only findOne()

   T findOne(ID id);
}

Further, write your repository as follows:

@Repository
interface ProductRepository extends IntermediateRepository {
  // only findOne() is visible
}
