如何使用WebClient使用Spring Hateoas CollectionModel？

我弄清楚了如何使用EntityModel，但到目前为止我还无法使用CollectionModel（Spring代码使用Groovy）

我的班级：

@Relation(value = "person", collectionRelation = "people")
class Person {
  long id
  String firstName
  String lastName
}

我的控制器：

CollectionModel<Person> getPeople() {
    Person person = new Person(
            id: 2L,
            firstName: 'Mark',
            lastName: 'Hamil'
    )
    Collection<Person> people = Collections.singleton(person)
    CollectionModel.of(people)
  }

CollectionModel<Person> model= this.webClient.get().uri('localhost:8080/api/people')
                  .retrieve()
                  .bodyToMono(new TypeReferences.CollectionModelType<Person>())
                  .block()

          List<Person> people = model.content

}

在上发帖并获得一些见解后，我能够让它正常工作。注意，这是在使用Groovy

首先，在控制器中，我确保产品设置为hal：

    @RequestMapping(method = RequestMethod.GET, produces = "application/hal+json")
    CollectionModel<Person> getPeople() {
       Link link = linkTo(PersonController).withSelfRel()
       List<EntityModel> entityModelList = [this.getPerson()]
    }

然后在调用api中：

    Mono<CollectionModel<EntityModel<Person>>> personCollectionModel = this.webClient
       .get()
       .uri('localhost:8080/uswf-api/people')
       .accept(MediaTypes.HAL_JSON)
       .exchange()
       .flatMap { response ->
           if (response.statusCode().isError()) {
              System.out.println('Error')
        } else {
          response.bodyToMono(new ParameterizedTypeReference<CollectionModel<EntityModel<Person>>>() {})
        }
    }

EntityModel<Person> getPerson() {
    Person person = new Person(
      id: 2L,
      firstName: 'Mark',
      lastName: 'Hamil'
    )
    Link link = linkTo(PersonController).slash(person.id).withSelfRel()
    EntityModel<Person> personEntityModel = EntityModel.of(person, link)

    personEntityModel
  }

    Mono<CollectionModel<EntityModel<Person>>> personCollectionModel = this.webClient
       .get()
       .uri('localhost:8080/uswf-api/people')
       .accept(MediaTypes.HAL_JSON)
       .exchange()
       .flatMap { response ->
           if (response.statusCode().isError()) {
              System.out.println('Error')
        } else {
          response.bodyToMono(new ParameterizedTypeReference<CollectionModel<EntityModel<Person>>>() {})
        }
    }

personCollectionModel.subscribe( { collectionModel -> collectionModel.content })
