在grails验证器中包含查询时获取堆栈溢出

堆栈跟踪：

altEmailAddress(blank: true, nullable: true, validator: {
    if (it == null || it == '') {
        return true
    } else {
        return (User.countByEmailAddress(it) > 0 && User.countByAltEmailAddress(it) > 0)
    }
}

Testcase:testFindValidEmailAddress花费了0.429秒 造成错误 无效的 栈溢出 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36） 在com.clearlynnovative.model.User$\uuuuClinit\uuuuClosure7\uClosure13.doCall（User.groovy:36）

在com.clearlynnovative.model.User$\uuuuClinit\uuuClosure7\uClosure13.doCall（User.groovy:36）上，您应该与NewSession一起使用-请参阅

编辑：为1.1.x添加：

如果您尚未使用1.2，并且withNewSession（）不可用，您可以在引导中自行连接它：

还有别的选择吗？我还没有升级到1.2，仍然在1.1.2上
