Expose custom endpoint to base-path in Spring Boot Data Rest - spring-boot

Question

I am using Spring Boot Data Rest and I can list all endpoints using follling url:
http://localhost:8080/api
It lists following endpoints:
{
"_links": {
"tacos": {
"href": "http://localhost:8080/api/tacos{?page,size,sort}",
"templated": true
},
"orders": {
"href": "http://localhost:8080/api/orders"
},
"ingredients": {
"href": "http://localhost:8080/api/ingredients"
},
"profile": {
"href": "http://localhost:8080/api/profile"
}
}
}
But I have a custom end point created like below in Controller
#RepositoryRestController
public class RecentTacosController {
private TacoRepository tacoRepo;
public RecentTacosController(TacoRepository tacoRepo) {
this.tacoRepo = tacoRepo;
}
#GetMapping(path = "/tacos/recent", produces = "application/hal+json")
public ResponseEntity<Resources<TacoResource>> recentTacos() {
PageRequest page = PageRequest.of(0, 12, Sort.by("createdAt").descending());
List<Taco> tacos = tacoRepo.findAll(page).getContent();
List<TacoResource> tacoResources = new TacoResourceAssembler().toResources(tacos);
Resources<TacoResource> recentResources = new Resources<TacoResource>(tacoResources);
recentResources.add(ControllerLinkBuilder.linkTo(ControllerLinkBuilder.methodOn(RecentTacosController.class).recentTacos()).withRel("recents"));
return new ResponseEntity<>(recentResources, HttpStatus.OK);
}
}
But this endpoint (http://localhost:8080/api/tacos/recent) is not listed when doing GET on base path.

implement ResourceProcessor<RepositoryLinksResource> in one of your class (could be the controller itself), add the following method:
#Override
public RepositoryLinksResource process(RepositoryLinksResource resource) {
resource.add( ... );
return resource;
}
... and create and add the proper link to your custom method there.
