我使用spring-data-rest将实体公开为(分页)休息资源.一切正常,但当我通过请求数据时RestTemplate,我得到一个无用的HATEOAS JSON(我没有要求).JSON似乎是一个PagedResources.我可以忍受,但JSON没有正确转换为对象.content里面没有.

库:

@RepositoryRestResource(collectionResourceRel = "people", path = "people")
public interface PersonRepository extends PagingAndSortingRepository<Person, Long>
{
    List<Person> findByLastName(@Param("name") String name);
}

客户:

public List<Person> getPersons()
{
    RestTemplate rt = new RestTemplate();
    System.out.println(rt.getForObject(URL, PagedResources.class).getContent().size());
    System.out.println(rt.getForObject(URL, PagedResources.class).getLinks().size());
    System.out.println(rt.getForObject(URL, PagedResources.class).getMetadata().getTotalElements());
    return new ArrayList<Person>(rt.getForObject(URL, PagedResources.class).getContent()); // <-- empty
}

System.out的:

0 // getContent().size()
4 // getLinks().size()
2 // getTotalElements()

卷曲:

C:\...>curl http://localhost:8080/spring-jsf-rest/rest/people
{
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/spring-jsf-rest/rest/people{?page,size,sort}",
      "templated" : true
    },
    "search" : {
      "href" …

我正在使用Spring Data REST 2.5.1,Jackson 2.8.0,Spring Boot 1.3.6.

我正试图通过RestTemplate从我的存储库中检索一个简单的实体列表.我可以在浏览器中找到终点,并获得预期的HAL数据.检索单个实体可以正常工作,如下所示.这些都使用默认的SDR端点(例如localhost:{port}/myEntity).

    ResponseEntity<Resource<MyEntity>> responseEntity =
    new RestTemplate()
        .exchange(
        uri + "/1",
            HttpMethod.GET,
            HttpEntity.EMPTY,
        new ParameterizedTypeReference<Resource<MyEntity>>() {}, port
        )

或者新的RestTemplate().getForEntity(uri +"/ 1",MyEntity.class,port)

正如许多SO问题似乎表明的那样,找到检索列表的示例是一个问题.我试着ParameterizedTypeReference用Resources,Resource,MyEntity,数组列表.一切都没有运气.

        ResponseEntity<Resources<Resource<MyEntity>>> responseEntity =
            new RestTemplate()
                    .exchange(
                    uri,
                    HttpMethod.GET,
                    HttpEntity.EMPTY,
                    new ParameterizedTypeReference<Resources<Resource<MyEntity>>>() {}
            , port
            )

当所谓的像上面几乎任何种类的Resources,Resource,List<MyEntity>,MyEntity,等等,ResponseEntity是空的.喜欢:

<200 OK,Resources { content: [], links: [] },{Server=[Apache-Coyote/1.1], Content-Type=[application/json;charset=UTF-8], Transfer-Encoding=[chunked], Date=[...]}>

字符串JSON在浏览器中如下所示.

{
"_embedded" : {
"myEntities" : …
