grails 没有错误并验证为 true 但不保存。
我有一个调用 .save() 的方法，但不将数据保存在数据库中。我试过ff：
- 称为 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
- put return objectInstance 并显示该值已更改
- 设置冲洗：假
但是在上述所有内容中没有显示任何验证失败，它仍然不会保存在数据库中。我尝试记录休眠状态，但它没有显示该实例的“更新”方法。Mayeb 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：

.....

on("cancel").to 'cancel'

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 在执行其他查询但不更新时显示所有选择和插入。
