使用PagedResourcesAssembler生成带有其他查询参数的链接

Question

我在我的REST控制器中使用了spring-data-common的PagedResourcesAssembler,我很高兴看到它甚至在响应中生成了下一个/上一个链接.但是,在我有其他查询参数(除了页面,大小,排序)的情况下,这些参数不包含在生成的链接中.我能以某种方式配置汇编程序以包含链接中的参数吗？

非常感谢,丹尼尔

您需要自己构建基本链接并将其传递给PagedResourcesAssembler的"toResource"方法.

@Controller
@RequestMapping(value = "/offer")
public class OfferController {

    private final OfferService offerService;

    private final OfferAssembler offerAssembler;

    @Autowired
    public OfferController(final OfferService offerService, OfferAssembler offerAssembler) {

        this.offerService= checkNotNull(offerService);
        this.offerAssembler= checkNotNull(offerAssembler);
    }

    @RequestMapping(value = "/search/findById", method = RequestMethod.GET, produces = { MediaType.APPLICATION_JSON_VALUE })
    public ResponseEntity<PagedResources<OfferResource>> findOfferById(
            @RequestParam(value = "offerId") long offerId, Pageable pageable,
            PagedResourcesAssembler<OfferDetails> pagedResourcesAssembler) {
        Page<OfferDetails> page = service.findById(offerId, pageable);

        Link link = linkTo(methodOn(OfferController.class).findOfferById(offerId,
                pageable,
                pagedResourcesAssembler)).withSelfRel();
        PagedResources<OfferResource> resource = pagedResourcesAssembler.toResource(page, assembler, link);
        return new ResponseEntity<>(resource, HttpStatus.OK);
    }
}

结果你会得到:

http://[your host]/[your app context]/offer/search/findById?offerId=[some offer id]{&page,size,sort}
