"* repository"という名前のBeanを作成する際にエラーが発生しました

私はmavenプロジェクトを持っています。 pom.xml："* repository"という名前のBeanを作成する際にエラーが発生しました

また、私はエンティティアドレスを持っています。

package root.entity; 
import javax.persistence.*; 
@Entity 
@Table(name = "Address") 
public class Address { 
... 
}

私はこのエンティティのリポジトリを持っています。

package root.repository; 
import org.springframework.data.jpa.repository.JpaRepository; 
import org.springframework.stereotype.Repository; 
import root.entity.Address; 
@Repository 
public interface AddressRepository extends JpaRepository<Address, Integer> { 
... 
}

実装のサービスインターフェイス。

package root.service.interfaces; 
import root.entity.Address; 
public interface AddressServiceInterface { 
... 
} 

package root.service; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 
import root.entity.Address; 
import root.repository.AddressRepository; 
import root.service.interfaces.AddressServiceInterface; 
@Service 
public class AddressService implements AddressServiceInterface{ 
... 
}

マイapplication.propertiesファイル：

#DB properties: 
db.driver=com.mysql.jdbc.Driver 
db.url=jdbc:mysql://localhost:3306/labsdb?useSSL=false 
db.username=root 
db.password=rootPassword

db.hibernate.show_sql=true 
db.entitymanager.packages.to.scan=root.entity 
db.hibernate.hbm2ddl.auto = create 

spring.datasource.driverClassName=com.mysql.jdbc.Driver 
spring.datasource.url=jdbc:mysql://localhost:3306/labsdb 
spring.datasource.username=root 
spring.datasource.password=rootPassword 

security.require-ssl=false

マイスタートファイル：

package root; 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
@SpringBootApplication 
public class TestApp { 
    public static void main(String[] args) { 
     SpringApplication.run(TestApp.class, args); 
    } 
}

をしかし、後に、私はエラーを持っているアプリケーション実行します、

をしてください助けて。私は同じ構造とロジックを持つsimpeアプリを持っていますが、うまくいきます。だから、私はどのように問題を修復するのか分からない。

解決方法はありましたか？ –

問題は、AddressRepositoryの実装がないことです。

@Repositoryや@Serviceなどのステレオタイプは、インターフェイスではなく実際の実装で使用することをお勧めします。

編集私は、あなたがAddressRepositoryインターフェイスの実装を提供するためにスプリングデータを使用していることがわかりました。たぶん何かがそこに正しく配線されていないでしょうか？投稿した例外は、AddressRepositoryを初期化できなかったことを示します。以前に春のデータを使用していなかったので、なぜこのことがわかりません。

私の他のプロジェクトは、実装なしで動作します。 –

私はあなたのサービスメソッドに

@Autowired 
Private AddressRepository addressRepository;

に見逃していると思います。
