Entity Manager EJB 查询找不到命名参数

Question

enter code here您好我正在使用实体管理器（EJB），它在内部依赖休眠来获取对象。

我的查询是........

TypedQuery<FraudDetectionInfoEntity> queryKount = em_oltp.createQuery("SELECT o FROM FraudDetectionInfoEntity o WHERE o.order.orderId=:orderId",FraudDetectionInfoEntity.class);
query.setParameter("orderId", orderEntity.getOrderId());
FraudDetectionInfoEntity infoEntity=queryKount.getSingleResult();

如果我运行该查询，我会收到以下错误。

org.hibernate.QueryParameterException: could not locate named parameter [orderId]
org.hibernate.QueryParameterException: could not locate named parameter [orderId]
12:46:58,639 ERROR [com.vip.enterprise.admin.web.controller.OrderPlacementController] (http-/127.0.0.1:8084-6) error com.vip.enterprise.service.exception.ServiceException: org.hibernate.QueryParameterException: could not locate named parameter [orderId]

您的代码没问题。缺少变量query 或queryKount？

TypedQuery<FraudDetectionInfoEntity> queryKount = em_oltp.createQuery("SELECT o FROM FraudDetectionInfoEntity o WHERE o.order.orderId=:orderId",FraudDetectionInfoEntity.class);  

query.setParameter("orderId", orderEntity.getOrderId());  
                <or>
queryKount.setParameter("orderId", orderEntity.getOrderId());
