これは重複しているようですが、私が探している答えを見つけることができず、私の問題は若干異なりますので、それをマーキングする前に気をつけてくださいダウンまたは複製 -プロパティが見つかりませんでしたorg.springframework.beans.factory.UnsatisfiedDependencyException：
ブッククラスのオブジェクトが挿入操作と削除操作を実行するような保存と削除機能を持っていて、なんとかブッククラスのプロパティとして取得しています。具体的な実装方法はです。との操作CrudRepositoryを使用しているときに私が行方不明になったり、何か他のものがありましたら、私はほとんど全ての回答をここで利用できましたが、助けてくれなかったuldはこの問題を通して私を案内します。
これは私が下記のコードで、現在直面しています例外である -
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'booksController': Unsatisfied dependency expressed through field 'bookService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookServiceImpl': Unsatisfied dependency expressed through field 'booksDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'booksDao': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property book found for type Books!
