I'm trying to access a mongodb collection via SDR. Working with following versions currently
<spring.version>4.1.9.RELEASE</spring.version>
<spring-data-rest>2.4.4.RELEASE</spring-data-rest>
<spring-data-mongodb>1.8.4.RELEASE</spring-data-mongodb>
My repository looks like
@RepositoryRestResource
@PreAuthorize("hasAuthority('ROLE_USER')")
public interface LinksRepository extends MongoRepository<Link, String> {
Page<Link> findAllByUsefulURLRegex(@Param("regex") String regex, Pageable p);
My model is defined as follows
@Document(collection = "links")
public class Link {
public Link() {}
@Id
private String id;
When I hit http://localhost:9090/api/links I get the following exception
java.lang.IllegalArgumentException: PersistentEntity must not be null!

Digging a little bit I found MongoMappingContext does not have the class Link as it should (I guess)
I spent few hours trying to figure it out but no luck. I'm not using spring boot and it feels it could be a ObjectMapper problem but I don't know, my domain and setup is simple....any help is greatly appreciated.
Thanks in advance.
After an unfair amount of time invested in debugging this to the guts I managed to make it work without any code change on my side with the following configuration:
<spring.version>4.1.8.RELEASE</spring.version>
<spring-data-rest>2.3.2.RELEASE</spring-data-rest>
<spring-data-mongodb>1.8.0.RELEASE</spring-data-mongodb>
<spring-data-jpa>1.9.0.RELEASE</spring-data-jpa>
It might work with another combination. Just beware.
