java.lang.IllegalArgumentException- 属性 不能为空
java.lang.IllegalArgumentException- Property must not be null
我正在使用 SpringBoot1.5.4，此外还有 spring-data-mongodb。现在，我正在使用 Json Query by @Query 注释从文档中获取数据。
我有以下实现：
在 PlayAndEarnProgramRepository:
@Query(value="{'_id' : ?0 , 'vouchers.is_deleted' : ?1, 'vouchers.is_expired' : ?2}",fields="{'vouchers' : 1}")
public List<VouchersPAndE> getActiveVoucherByplayAndEarnId(String id,Boolean isDeleted,Boolean isExpired);
边玩边赚模式：
@Id
@Field(ID)
private String id;
@Field(PLAYANDEARNID)
private String playAndEarnId = UUID.randomUUID().toString();
@Field(MERCHANTID)
private String merchantId;
@Field(VOUCHERS)
private List<VouchersPAndE> vouchers;
以及repoMethod的调用：
playAndEarnProgramRepo.getActiveVoucherByplayAndEarnId(program.getId(),false,false);
我想获取有效的代金券。但出现以下异常：

谁能告诉我我做错了什么？
您使用了错误的 return 类型，因为错误表明没有与结果绑定的 id 字段
您需要在 Play&Earn 模型中绑定结果：
db.PlayAndEarn.find({"_id" : ID , "vouchers.is_deleted" : false, "vouchers.is_expired" : FALSE},{"vouchers" : 1})
它将显示数据格式。
