Question

enter code here您好我正在使用实体管理器（EJB），它在内部依赖于hibernate来获取Object。

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();

我收到了以下错误如果我运行该查询。

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());

实体管理器EJB查询无法找到命名参数
