在 Spring Boot Data Rest 中将自定义端点公开到基本路径

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

我正在使用 Spring Boot Data Rest,我可以使用 follling url:

列出所有端点
http://localhost:8080/api

它列出了以下端点:

{
"_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端点,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);
}

}

但是在基本路径上执行 GET 时未列出此端点 (http://localhost:8080/api/tacos/recent)。

在您的 class 之一(可能是控制器本身)中实现 ResourceProcessor<RepositoryLinksResource>,添加以下方法:

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

... 并创建适当的 link 并将其添加到您的自定义方法中。
