Answer 1

@Repositoryは、注釈の設定のためです。 Beanを2つの方法、xml、注釈で定義しようとします。これは悪い習慣であり、さらなる問題につながる可能性があります。

は、XMLから次の行を削除するようにしてください： <beans:bean id="employeeRepo" class="com.spring.crud.dao.EmployeeRepo" abstract="true"/>

私はあなたが@ComponentScanアノテーションを使用したとします。

Answer 2

ご協力いただきありがとうございます..！

私は解決策を見つけました。最新バージョンのSpringコアバージョンを更新することによって、Beanを作成します。
