Question

所以我试图在grails中执行以下查询

User user = springSecurityService.currentUser
def approverGroupList = approverGroupService.getApproverGroupsByUser(user.id)
return VerificationRequest.executeQuery("select distinct v.fundTransfer from VerificationRequest v where v.fundTransfer.creator.corporateHouse=:corporateHouse and v.verified = false and v.fundTransfer.status ='QUEUED' and v.approverGroup in (:approverGroupList)", [corporateHouse:corporateHouse],[approverGroupList:approverGroupList])

但是我得到以下例外：

/fund-transfer/list-verification-requests
Class
    org.hibernate.QueryException
Message
    Not all named parameters have been set: [approverGroupList] [select distinct v.fundTransfer from VerificationRequest v where v.fundTransfer.creator.corporateHouse=:corporateHouse and v.verified = false and v.fundTransfer.status ='QUEUED' and v.approverGroup in (:approverGroupList)]

另外，corporateHouse是一个传递给执行此查询的方法的对象，它不是null。可能是什么原因？

P.S。我是grails的新手！

Answer 1

Looks like参数应位于一个地图中，如下所示：

[corporateHouse:corporateHouse, approverGroupList:approverGroupList]

Answer 2

您已将两张地图传递给executeQuery：

VerificationRequest.executeQuery("...", [corporateHouse:corporateHouse],[approverGroupList:approverGroupList])

它应该是一个有两个值的地图：

VerificationRequest.executeQuery("...", [corporateHouse:corporateHouse, approverGroupList:approverGroupList])

根据documentation，第二张地图被视为带有其他参数的地图。

Answer 3

这意味着您尚未在查询中设置所有参数。您错过了一些检查查询执行代码

异常的原因是什么＆org.hibernate.QueryException消息并未设置所有命名参数：＆＃39;可能是？
