Spring Data Rest - Base Repository using Generics not working - spring-boot

Question

I want to disable export of DELETE operation using Spring Data rest using generics. Any repository which extends from BaseResourceRepository should not export DELETE verb. I am using groovy
#NoRepositoryBean
interface BaseResourceRepository<T extends BaseEntity, ID extends Serializable> extends PagingAndSortingRepository<T, ID> {
#Override
#RestResource(exported = false)
void delete(T t)
}
#RepositoryRestResource(collectionResourceRel = "contacts", path = "contacts")
interface ContactRepository extends BaseResourceRepository<Contact, Long> {
}
I want to disable the DELETE operation for /contacts endpoint
This configuration is still allowing me to DELETE the contact resource
Any help is appreciated.
Thanks in advance

See the official documentation regarding hiding CRUD methods:
https://docs.spring.io/spring-data/rest/docs/current/reference/html/#customizing-sdr.hiding-repository-crud-methods
As mentioned there you need to hide both methods.
Should look like this (may contain errors due to no IDE present ;))
#NoRepositoryBean
interface BaseResourceRepository<T extends BaseEntity, ID extends Serializable> extends PagingAndSortingRepository<T, ID> {
#Override
#RestResource(exported = false)
void delete(T t)
#Override
#RestResource(exported = false)
void delete(ID id);
}
Edit
An approach to give a try to
The base repository
package com.stackoverflow.generics.repository;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.data.repository.NoRepositoryBean;
import org.springframework.data.repository.Repository;
#NoRepositoryBean
public interface NoDeleteRepository <T, ID> extends Repository<T, ID> {
T findOne(ID id);
Iterable<T> findAll();
Iterable<T> findAll(Sort sort);
Page<T> findAll(Pageable pageable);
// Define other necessary methods
}
The repository for an concrete entity
package com.stackoverflow.generics.repository;
import com.stackoverflow.generics.repository.SomeEntity;
public interface SomeNoDeleteRepository extends NoDeleteRepository<SomeEntity, Long> {
}
The repository does not expose the delete method therefore I assume it wont be exposed as REST endpoint. Can't test it as my spring does not expose all repositories as rest resource. Some misconfiguration I think.
public class SomeService {
private final SomeNoDeleteRepository repository;
public void deleteSome(Long id) {
// cannot resolve method delete
repository.delete(id);
}
}
