Spring data rest, HATEOAS exposeIds

Para que las rests HATEOAS muestren los campos id de cada elemento:

 @Component  
 @Slf4j  
 public class SpringDataRestCustomization extends RepositoryRestConfigurerAdapter {  
   @Override  
   public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {  
     listMatchingClasses(Entity.class).forEach(entity -> config.exposeIdsFor(entity));  
   }  
   public List<Class> listMatchingClasses(Class annotationClass) {  
     List<Class> classes = new LinkedList<Class>();  
     ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(true);  
     scanner.addIncludeFilter(new AnnotationTypeFilter(annotationClass));  
     for (BeanDefinition bd : scanner.findCandidateComponents(Project.class.getPackage().getName())) {  
       try {  
         classes.add(Class.forName(bd.getBeanClassName()));  
       } catch (ClassNotFoundException e) {  
         log.error("listMatchingClasses problem", e);  
       }  
     }  
     return classes;  
   }  
 }
