spring、hibernate、maven に関するチュートリアルを行っています。org.springframework.beans.factory.BeanCreationExceptionエラーメッセージが表示されました。チュートリアルへのリンクは次のとおりです。

http://www.lulu.com/shop/arulkumaran-kumaraswamipillai-and-sivayini-arulkumaran/tutorial-java-maven-2-eclipse-jsf/ebook/product-1603040.html;jsessionid=0C532C55C373D3DDB01AC49ACE23A5E2

hibernateTemplate のものをコードに入れた後、このチュートリアルを進めます。

私はチュートリアルが言ったことを正確にしました。

しかし、私はこのエラーが発生し続けます。エラーが発生した場合でも、残りのコードをEclipseに書き続けました。
