spring - Spring Autowire エラーは、この依存関係の autowire 候補として適格な少なくとも 1 つの Bean を予期していました

Question

このプロジェクトで Bean を自動配線しようとしていますが、エラーが発生し続けます

この依存関係のオートワイヤー候補として適格な少なくとも 1 つの Bean が必要です。依存関係アノテーション: {@org.springframework.beans.factory.annotation.Autowired(required=true)"

ジャワ:

私は同じ問題を抱えていました。次のコードでパッケージ名を適切に命名した後、これを解決しました<context:component-scan base-package="com.mysweethome"></context:component-scan>

すべての提案を試してもうまくいかない場合は、最後にサーバーのプロジェクトファイルを削除する方法があります。たとえば、Tomcat を使用している場合は、webappsディレクトリとディレクトリに移動しwork、対応するプロジェクトを削除します。ファイル。削除するときは注意してください。

私はこれで同じ問題を解決したので、IDEでprojectとをクリアしたにもかかわらず、プロジェクトキャッシュによる原因を考えています。server

spring - Spring Autowire エラーは、この依存関係の autowire 候補として適格な少なくとも 1 つの Bean を予期していました
