@ DBRef與彈簧數據休息

我有一個類叫做Veiculo和Agencia，其中Veiculo擁有作爲參考Agencia。當它不是一個列表，我可以通過的URI參考以及以下example。但是如何在列表中執行操作？我很感激，如果有人能幫助我@ DBRef與彈簧數據休息

實體沒有getter和setter

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; 

}

通訊社

@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庫

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

服務Veiculo實例資源暴露兩個Contato和Agencia鏈接到association resource。您可以使用媒體類型text/uri-list向它們發送有效負載以分配對Veiculo的引用。

這發生在我做出/ veiculos，/ veiculos/{ID} GET請求和/ veiculos/{ID}/agencias /（編號）：'{ 「時間戳」：1437414418319，「狀態」：500 ，「error」：「Internal Server Error」，「exception」：「org.springframework.dao.InvalidDataAccessResourceUsageException」，「message」：「no db;嵌套異常是com.mongodb.MongoInternalException：no db」，「path」：「/ api/veiculos/55ad30e8ccf29fbf6011411e/agencias」 }' –

問題是，應用程序運行Fongo時，mongoDB在內存中 –
