Printemps de Démarrage de l'Application n'a pas pu démarrer avec classpath

Quelle belle journée, n'est-ce pas?

J'espère que quelqu'un de cette communauté peut m'aider.

Version De Tomcat 7,
Servlet API 3.0

Je voudrais commencer ma Printemps de Démarrage projet dans un tomcat à l'aide d'un .guerre. Voilà mon code de printemps de démarrage de l'application:

Principal De La Classe

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "com.###.dashboard")
@EnableJpaRepositories
@EntityScan(basePackages = "com.###.dashboard.domain")
public class Dashboard extends SpringBootServletInitializer  {

    public static void main(String[] args) {
        SpringApplication.run(new Object[] {Dashboard.class}, args);    
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Dashboard.class);
    }


}

Où j'ai besoin de configurer le classpath? J'ai pensé que je n'ai pas besoin d'en définir un .de fichiers xml.

Merci!
