Consider defining a bean of type 'package' in your configuration [Spring-Boot]

It might be because the project has been broken down into different modules.

@SpringBootApplication
@ComponentScan({"com.delivery.request"})
@EntityScan("com.delivery.domain")
@EnableJpaRepositories("com.delivery.repository")
public class WebServiceApplication extends SpringBootServletInitializer {

There is a chance...
You might be missing @Service, @Repository or @Component annotation on your respective implementation classes.
