Question

ich das Beispiel Frühlings-Boot und Spring-Daten für eine Übung mit, kann aber nicht die Anwendung spielen, der folgende Fehler auftritt:

Answer 1

eine

@EntityScan(basePackageClasses=br.com.boot.domain.Cep.class) 

zu Ihrem Application.class

http://docs.spring.io/spring-boot/docs/current/reference/html/howto-data-access.html#howto-separate-entity-definitions-from-spring-configuration

Answer 2

Sie müssen hinzufügen Hibernate sagen, wo Ihre @Entity Klassen zu finden. Erraten in Ihrem Fall sollte diese

@EntityScan(basePackageClasses=Cep.class) 
... 
public class Application { 

    ... 

}
