Bean Creation Exception spring boot

Question

私は自分自身で春のブートを学習しており、この場合は自動的にurl（/ messages）に投稿してresultを返すWebプロジェクトを実行しようとしています。データをデータベースに送信します。入れ子にされたBean作成の例外があり、何がうまくいかないのか理解できません。私は2〜3日から春に取り組んでおり、JPA、DAOなどのデータベースへの接続を冬眠させています。インポートとチェックが簡単にできるように私のプロジェクトを下にアップロードしました。これについての助けがあれば大きな助けになるでしょう。エラーとトラブルシューティングの方法を理解するための助言があれば、私はそれをよりよく学ぶのに役立ちます。私はインターネット上のリソースを検索しましたが、なぜそれが起こっているのか理解できませんでした。

パッケージリストに@Componentscanリポジトリパッケージがありません。また、MessageRepositoryクラスには@Repositoryアノテーションがありません。

1つの提案ですが、com.demo.service,com.demo.repositoryなどの他のすべてのパッケージに共通のパッケージがあります。今は@Componentscan(basePackages = "com.demo")を使用できます。だから、あなたは "間違いなく"どんなパッケージも忘れることはありません。ただし、アプリケーションクラスは共通パッケージ（com.demo）でそのまま使用してください。このようなもの。

package com.demo; 

@SpringBootApplication 
@EnableScheduling 
@ComponentScan(basePackages = "com.demo") 
public class MarkableApplication { 

    public static void main(String[] args) { 
    .... 
} 

これはなぜ必要なのですか。しかし、私は過去に別のパッケージでApplication.classを持っていたこともありました。私が共通のパッケージに移動した後、私は構築することができました。 @AutowiredをMessageServiceクラスのフィールドに追加して、セッターメソッドを削除します。

@Autorwired 
private MessageRepository messagerepository;
