ネストされた例外は、java.lang.IllegalArgumentExceptionがある：未マネージ型：クラス

Question

私はsrc/main/resources/application.properties

で接続プロパティを参照のうえ、 JPAと Hibernateを使用して、実行時に PostgreSQL DBに接続している JpaRepositoryにアクセス Serviceと Spring-Boot applicationを展開しようとしています

ビルドされた.WARをTomcatにデプロイするとき、アプリケーションは以下のエラーログに記載されているようにエラーで起動することに失敗しています。

誰かがこのエラーの意味を教えてください。

注私はMyServiceImplとMyRequestBodyクラスでトラブルポイントを指摘してきたが、私はSpringフレームワークに新しいです、私は、エラーの正確な理由を取得しておりません。次のように

私の春ブーツスタータープロジェクト内の関連するクラスの定義は以下のとおりです。

春ブートアプリケーションMyServiceでのオートワイヤリング

@SpringBootApplication 
@ComponentScan(<root package name under which all subpackages containing relevant classes >) 
public class MySpringBootApplication extends SpringBootServletInitializer { 

私の春ブーツRestControllerクラス（クラスインスタンス）

@RestController 
public class MyController { 

    @Autowired 
    MyService myService; 

マイサービスインターフェース（I任意@Serviceアノテーションを提供していない）

public interface MyService { 
    //all service method definitions 
} 

PostgreSQLのDBに

@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. 

} 

を動作させるオートワイヤリングリポジトリインスタンスと

スプリングServiceImplクラス

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); 
} 

私の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 

（Tomcatで.WARをデプロイの）エラーログ

春はあなたのエンティティを認識しません。 MySpringBootApplicationクラスを表す必要があります@EntityScan("your.entities.package")
