I am building a web application using spring-data-jpa, but now I have error:
Exception in thread "main" java.lang.NullPointerException
at com.example.test.demo.config.service.RegionServiceImpl.getAll(RegionServiceImpl.java:40)
at com.example.test.demo.DemoApplication.main(DemoApplication.java:45)
Repository:
import com.example.test.demo.config.entity.Region;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface RegionRepository extends JpaRepository<Region, Integer> {
}
Service:
@Component
public class RegionServiceImpl implements RegionService {
@Autowired
private RegionRepository regionRepository;
And model:
@Entity
//@Table(name = "geo.region")
@Table(name = "region", schema = "geo")
public class Region implements Serializable {
@Id
@GeneratedValue
@Column(name = "id", length = 6, nullable = false)
private Integer id;
@Column(name = "title")
private String title;
public Region() {
}
But now I have NPE on this step:
@Autowired
private RegionRepository regionRepository;
Pls, help! :(
