Rest 不使用Spring数据的Spring hateoas分页

我想为我的RESTAPI实现分页。 该应用程序使用Spring Hateoas 0.8、Spring MVC 3.2.4和Spring Integration 2.2.4。 我看到Spring Hateoas有PagedResources类，但这并没有将结果拆分成页面。 似乎spring数据需要正确创建页面，并正确创建上一个和下一个链接

我尝试过此操作，但链接不正确，所有结果都会显示：

    @RequestMapping(value = "/resources", method = RequestMethod.GET, produces="application/json")
public HttpEntity<Resources<RequestResource>> showAllAsResources() {
    Iterable<? extends Request> people = requestAccess.getRequests();
    RequestAssembler assembler = new RequestAssembler();
    List<RequestResource> resources = assembler.toResources(people);
    Resources<RequestResource> wrapped = new Resources<RequestResource>(resources, linkTo(RequestsController.class)
            .withSelfRel());
    return new HttpEntity<Resources<RequestResource>>(wrapped);
}

是否有任何Spring类可以帮助我实现这一点，或者我需要实现自己的分页

非常感谢,， 马丁

更新

使用下面代码中的解决方案会产生下面的响应，尽管我认为这有点过分了。有没有任何Spring助手类可以实现同样的功能

@RequestMapping(value = "/resources1", method = RequestMethod.GET, produces="application/json")
public HttpEntity<PagedResources<Resource<RequestResource>>> viewResources1(Pageable pageable)
{   
    int page = pageable.getPageNumber();
    int count = pageable.getPageSize();
    RequestAssembler requestAssembler = new RequestAssembler();

    List<Request> requests = requestAccess.getRequests2();
    int max = (count*(page+1)>requests.size())? requests.size(): count*(page+1);

    Page<Request> pageRequests = new PageImpl<Request>(requests.subList(page*count, max), pageable, requests.size());

    return new ResponseEntity<PagedResources<Resource<RequestResource>>>(pagedResourcesAssembler.toResource(pageRequests, requestAssembler), HttpStatus.OK);
}

听起来您想利用

spring data rest的优点，而不需要真正的存储库“支持”。这就是这个问题的内容：不完全是，我已经在使用SpringHateOAS，并且有一个SpringIntegration的项目列表。我只是想把这些“转换”成分页对象。可能吗？也许我不理解这个问题，但看起来您正在将所有数据发送到客户端，现在您想知道为什么所有数据都发送到客户端。我显然没有正确使用分页类。他们能够在客户端上正确显示元数据和链接，但所有数据都会被发送，而不是某个特定页面的数据。这有意义吗？页面类型应该包含所有数据还是只包含数据的一部分，即页面大小为5-是否只有5项？
