Question

我有一个名为Veiculo和Agencia的班级，其中Veiculo拥有作为参考Agencia。当它不是列表时，我可以传递 URI引用以及以下example。但是我怎么做一个清单呢？如果有人可以帮助我，我感激不尽

没有getter和setter的实体

Veiculo

@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;

}

AGENCIA

@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;
}

Veiculo存储库

@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);
}

Answer 1

提供Veiculo个实例的资源会为Contato和Agencia提供指向association resource的链接。您可以向媒体类型text/uri-list发布有效负载，以指定对Veiculo的引用。

带有Spring Data Rest的@DBRef
