在Spring Boot数据Rest中公开自定义endpoint到基本路径

Question

我正在使用Spring Boot Data Rest，我可以使用下面的URL列出所有endpoint：

http://localhost:8080/api

它列出了以下endpoint：

{
"_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"
    }
}

}

但我在控制器中创建了一个自定义endpoint，如下所示

@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);
}

}

但是这个终点(http://localhost:8080/api/tacos/recent)执行“在基本路径上获取”时未列出。

实现ResourceProcessor

  @Override
  public RepositoryLinksResource process(RepositoryLinksResource resource) {
    resource.add( ... );
    return resource;
  }

... 并在那里创建并添加到自定义方法的适当链接。
