Spring Bootのエラーの解決策がわかりません

Ecripseを使ってSpring Bootプログラミング入門という参考書をすすめているのですが、

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloController': Injection of autowired dependencies failed;nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.yamada.springboot.MyDataRepository com.yamada.springboot.HelloController.repository;No bean named 'entityManagerFactory' is defined

というエラーが出て困っています。
社内にSpringがわかる人がいないため、どなたかわかる方がいらっしゃいましたらご教授お願いいたします。念のため、コードも載せます。

ちなみに、Spring Bootのバージョンは1.3.6で文字コードはutf-8です。
