[Java Spring] Controlling API Exposure & Override Endpoint Name

 @RestResource(exported = false): makes the endpoint no longer visible for public.

package com.example.ec.repo;

import com.example.ec.domain.TourPackage;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import org.springframework.data.rest.core.annotation.RestResource;

import java.util.Optional;

// Rename the endpoint
@RepositoryRestResource(collectionResourceRel = "packages", path = "packages")
public interface TourPackageRepository extends CrudRepository<TourPackage, String> {

    /**
     * Find Tour Package by name.
     *
     * @param name name of the package
     * @return Optional of TourPackage
     */
    Optional<TourPackage> findByName(@Param("name")String name);

    @Override
    @RestResource(exported = false)
    <S extends TourPackage> S save(S s);

    @Override
    @RestResource(exported = false)
    <S extends TourPackage> Iterable<S> saveAll(Iterable<S> iterable);

    @Override
    @RestResource(exported = false)
    void deleteById(String s);

    @Override
    @RestResource(exported = false)
    void delete(TourPackage tourPackage);

    @Override
    @RestResource(exported = false)
    void deleteAll(Iterable<? extends TourPackage> iterable);

    @Override
    @RestResource(exported = false)
    void deleteAll();
}
