Spring BeanCreationException：ファクトリメソッドによるBeanのインスタンス化がネストされた例外に失敗しました

Springを使い始めて、Security、Hibernate、Thymleafを使用してアプリを構築しようとしています。

私は何日も私を立ち往生させたこのエラーがあります。

これがログです：

エンティティマネージャでスキャンする正しいパッケージがあることを確認してください。

entityManagerFactory.setPackagesToScan（env.getProperty（ "entitymanager.packagesToScan"））;ここで正しいパスが設定されていますか？エンティティマネージャーが何であるかわからず、スキャンするパスを設定していますか

アプリケーションでbaseClassが定義されている場合は、使用してみてください

entityManagerFactoryBean.setPackagesToScan(new String[]{BaseEntity.class.getPackage().getName()});
