Spring boot Auto-generated controllers - spring-boot

Question

In the official Spring tutorial code source coode there are no controller required, so I didn't put them in my sample, however when I try to run my simple app I keep getting for http://localhost:8080/ or for http://localhost:8080/invoice the error:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing
this as a fallback. Thu Mar 09 10:18:51 CET 2017 There was an
unexpected error (type=Not Found, status=404). No message available

import org.springframework.data.repository.query.Param;
import java.util.List;
public interface InvoiceRepository extends PagingAndSortingRepository<Invoice, Long> {
List<Invoice> findByIssuedBy(#Param("issuer")String issuer);
}
and APP:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class QbsApplication {
public static void main(String[] args) {
SpringApplication.run(QbsApplication.class, args);
}
}
1. What seems to be the problem?
2. Can this be the lombok causing the issue (user the start.spring.io initializer though)?

Answer 1

You forgot to annotate your repository with #RepositoryRestResource. If you don't, Spring will not auto generate the url mappings and it will just act as a normal repository. This is a feature of spring-data-rest. So, in your case:
#RepositoryRestResource(collectionResourceRel = "invoices", path = "invoices")
public interface InvoiceRepository extends PagingAndSortingRepository<Invoice, Long> {
List<Invoice> findByIssuedBy(#Param("issuer")String issuer);
}
Now curl http://localhost:8080/invoices will return all invoices.
Refer to the Spring Data Rest documentation for more info.
