我有一个名为Veiculo
和Agencia
的类,其中Veiculo
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。但是我怎么办清单呢?我很高兴有人能帮助我
没有getter和setter的实体

@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;
}

@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资料库
@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);

最佳答案
为Veiculo
和Contato
提供资源的Agencia
实例公开指向association resource的链接。您可以向它们发布媒体类型为text/uri-list
的有效负载,以为Veiculo
分配引用。
