package br.com.alura.forum.controller.repository;

import org.springframework.data.jpa.repository.JpaRepository;

import br.com.alura.forum.modelo.Curso;

//necessario herdar JPArepository passando generico (entidade, tipo)
public interface CursoRepository extends JpaRepository<Curso, Long> {

    Curso findbyNome(String nomeCurso);

}
