Spring Data: Override save method

Question

I\'m considering spring data for a project. Is it possible to override the per default generated save method? And if yes, how?

Answer 1

If you are using interfaces only you can use default methods to do simple overrides of the CrudRepository or JpaRepository:

public interface MyCustomRepository extends CrudRepository {

  @Override
  default  S save(S entity)
  {
    throw new UnsupportedOperationException("writes not allowed");
  }
}
