誰かがこのエラーの意味を助けてくれますか?
注MyServiceImpl
およびMyRequestBody
クラスの問題点に注意しましたが、Springフレームワークを初めて使用するため、エラーの正確な理由はわかりません。
Spring Boot Starterプロジェクトの関連クラスの定義は次のとおりです。
スプリングブートアプリケーション
@SpringBootApplication
@ComponentScan(<root package name under which all subpackages containing relevant classes >)
public class MySpringBootApplication extends SpringBootServletInitializer {
私のSpring-Boot RestControllerクラス(MyServiceクラスインスタンスの自動配線)
@RestController
public class MyController {
@Autowired
MyService myService;
My Serviceインターフェース(@Serviceアノテーションを提供していません)
public interface MyService {
//all service method definitions
}
PostgreSQL DBで動作する自動配線リポジトリインスタンスを持つSpring ServiceImplクラス
@Service("myService")
public class MyServiceImpl implements MyService {
@Autowired
private MyRepository myRepository; <-- **ERROR -- Bean not found**
//other default services e.g. find, add, delete, update, etc.
}
マイリポジトリクラス
@Repository
public interface MyRepository extends JpaRepository<MyRequestBody, Long> {
@Query("select h from MyRequestBody h where h.column1 = ?1")
List<MyRequestBody> findByColumn1(String col1);
}
エンティティクラス
@Entity
@Table(name = "myTable", schema = "my_db")
public class MyRequestBody { <-- **ERROR -- Not a managed class type**
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE)
private Long id;
@Column(name = "column1")
private String column1;
//getter and setter AND toString methods
