Spring boot 2.0.3.RELEASE, Spring data rest, application error, failed to start - spring-boot

Question

Unable to start spring boot application.
Repository and its associated domain
import com.vircosolutions.mobileapi.domain.Awards;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
#RepositoryRestResource(exported = false)
public interface AwardsRepository extends JpaRepository<Integer,
Awards> {
}
Domain
import lombok.Getter;
import lombok.Setter;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;
import java.util.Objects;
#Getter

Awards awards = (Awards) o;
return id == awards.id &&
Float.compare(awards.rating, rating) == 0 &&

return "Awards{" +
"id=" + id +
", user=" + user +
", rating=" + rating +

}
}
Main application file looks like
#EnableSpringDataWebSupport
#SpringBootApplication
public class MobileApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return super.configure(builder);
}
public static void main(String[] args) {
SpringApplication.run(MobileApplication.class, args);
}
}
I debugged a lot but unable to find out the root cause. Stach trace is given below. If you need any other file and code it can be provided. Any help will be highly appreciated.

Answer 1

You have specified the generic types in the wrong order hence the error Not a managed type: class java.lang.Integer
Try:
#RepositoryRestResource(exported = false)
public interface AwardsRepository extends JpaRepository<Awards, Integer> {
}
As an aside, and in line with naming conventions, you should also rename you entity Awards to Award and rename the repository accordingly.
