My repository:
@Repository
public interface DietaRepository extends JpaRepository<Dieta, String> {
Dieta findByName (String name);
}
And my Controller:
@RestController
public class DietaController {
@Autowired
private DietaRepository dietaRepository;
@GetMapping("/dieta")
public List<Dieta> getAllNotes() {
return dietaRepository.findAll();
}
}
Application java class:
@Configuration
@SpringBootApplication
@EnableJpaRepositories
@EntityScan ( basePackages = { " com.diet4you.LapkoEkaterina" })
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
