}

CrudRepository interface.
The CrudRepository extends Repository interface. It has below methods to perform CRUD operation.
<S extends T> S save(S entity) – See more details about save() method here.
<S extends T> Iterable<S> saveAll(Iterable<S> entities) – See more details about saveAll() method here.
Optional<T> findById(ID id) – See more details about findById() method here.
Iterable<T> findAll() – See more details about findAll() method here.
Iterable<T> findAllById(Iterable<ID> ids) – See more details about findAllById() method here.
long count() – See more details about count() method here.
void deleteById(ID id) – See more details about deleteById() method here.
void delete(T entity) – See more details about delete() method here.
void deleteAll(Iterable<? extends T> entities) – See more details about deleteAll() method here.
