Parameter 0 of constructor in ComponentClass required a bean of type 'JpaRepository' that could not be found

Question

@Repository
public interface SomeJpaRepository extends JpaRepository<SomeEntity, String>
{
   @Modifying
  //....
}

my component:

@Component
@Slf4j
public class SomeComponentClass
{
   private final SomeJpaRepository repository;
   private final SomeMapper someMapper;
   private final int property_1;
   private final int property_2;

   public SapRequestQueue(SomeJpaRepository somejpaRepository, SomeMapper someMapper,
                          @Value("${xxx.property_1}") int property_1, @Value("${xxx.property_2}") int property_2)
   {
      this.property_1 = property_1;
      this.property_2 = property_2;
      this.someMapper = someMapper;
      this.somejpaRepository = somejpaRepository;
   }

My error:

Maybe you can try adding

@EnableJpaRepositories(basePackages = "path.toservice.repository")

to the configuration. If that solves your problem, then probably something is wrong with your packages structure.

In your class "SomeComponentClass", you could try putting the annotation @Autowired above your private repo, and remove it from your constructor.

@Autowired
private final SomeJpaRepository repository;

public Constructor(prop1, prop2, someMapper){
      this.property_1 = prop1;
      this.property_2 = prop2;
      this.someMapper = someMapper;
}

The issue is related to the order of beans creation, so it is better to create SomeJpaRepository in the context file to avoid similar issues Check this answer
