Question

我有一个名为veiculo和agencia的类，其中veiculo拥有作为引用的agencia。当它不是列表时，我可以传递URI引用以及以下示例。但我怎么做当一个清单？如果有人能帮助我，我很感激

没有getter和setter的实体

细静脉

@Document
public class Veiculo{

    @Id
    private String id;

    @Indexed(unique = true)
    private String nome;
    private String tipo;
    @DBRef
    List<Contato> contatos;

    @DBRef
    List<Agencia> agencias;

}

阿根西亚

@Document
public class Agencia {

    @Id
    String id;
    @NotNull
    String nome;

    @CreatedBy
    String createdBy;

    @LastModifiedBy
    String lastModifiedBy;

    @CreatedDate
    @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
    Date createdAt;

    @LastModifiedDate
    @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
    Date lastModified;
}

静脉储存库

@RepositoryRestResource(collectionResourceRel = "veiculos", path = "veiculos")
public interface VeiculoRepository extends MongoRepository<Veiculo, String> {
    Veiculo save(Veiculo veiculo);
    List<Veiculo> findAll();
}

Agencia存储库

@RepositoryRestResource(collectionResourceRel = "agencias", path = "agencias")
public interface AgenciaRepository extends MongoRepository<Agencia, String> {

    Agencia save(Agencia t);
    List<Agencia> findAll();
    Agencia findByNome(@Param("nome") String nome);
}

服务于veiculo实例的资源为contato和agencia公开到关联资源的链接。您可以将媒体类型为text/uri-list的有效负载发布给它们，以分配对veiculo的引用。
