在Spring Boot Data Rest中将自定义端点暴露给基本路径

问题描述 投票:1回答:1

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"
    }
}

}

但是我在Controller中创建了如下所示的自定义端点

@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)。

在你的一个类中实现ResourceProcessor<RepositoryLinksResource>(可能是控制器本身),添加以下方法:

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

...并在那里创建并添加适当的链接到您的自定义方法。
