Hibernate grails无错误并验证true，但不保存。休眠不更新

grails无错误并验证true，但不保存

我有一个调用.save（）的方法，但没有将数据保存在数据库中。我试过ff：

调用FailOnError:true，但不显示任何失败的内容

validate（），它确实返回true

hasErrors（），它确实返回true put

放置returnobjectinstance并显示值已更改

设置齐平：false

但是，在上面所有这些没有显示任何验证失败的情况下，它仍然不会保存在数据库中。我尝试记录hibernate，但它没有显示该实例的“update”方法。这就是为什么没有更新发生的原因。但我最大的问题是为什么？为什么它在没有错误或任何东西的情况下不调用更新？我错过了什么。谢谢

这是我的控制器代码：

    cancel {
        redirect( action:"obpView", controller:"olderBlind", params:[caseId: flow.obpCaseInstance.olderBlind.cmCaseIdCmCase])
    }
}

这是我的保存服务代码

def CmCase saveUpdateCase(CmCase caseInstance, Users currentUser) {
    if (!caseInstance.save(flush:true)) {

        if (log.isDebugEnabled()) {
            caseInstance.errors.allErrors.each { log.debug it }
        }

        throw new CaseException(message: "case.cmCase.exception", caseInstance: caseInstance)
    }
    return caseInstance
}

Hibernate在执行其他查询时显示所有select和insert，但不显示update

更新：我发现当我在保存之前再次调用objectInstance.get（id）时，它现在正在保存。但我为什么要重新得到它？这是一种行为吗？如果是，请卸下

CmCase

。如果是服务方法，请删除

def

。是否将正确的对象传递到

saveUpdateCase

？对象从何处获取？我可以通过将.read（）方法更改为.get在保存之前和之后进入控制器（当它重新进入查看模式时）来解决此问题。问题消失了，但在单击“取消”按钮时生成了另一个错误，该错误为null瞬态。因此，我必须做一个变通，通过将objectInstance存储在流中，将旧值分配给objectInstance。从数据库中获取新数据不会像我获取数据时那样有效，它会获取“脏”数据。我仍然对解决方案不满意，但这是我现在能想到的解决方案。我已经修改了代码以获得更清晰的视图。
