Question

我有这个班级

class ScanRequest4Command implements Validateable {

    String _ScanType

    static constraints = {
        pScanType inList:["a", "b"]
    }
}

此代码在grails 2.4.4中运行良好最近，我们开始升级到grails 3.1.16

现在当我尝试运行代码失败并抛出以下异常时：

java.lang.IllegalArgumentException: object is not an instance of declaring class

没有多大帮助。如果我删除代码传递的inList约束，意味着问题出现在inList约束中。

所以在测试失败之后，我发现如果我将成员的名字改为代码通过的pScanType。

所以我的问题是：

是成员名称前缀中不允许的下划线？如果是这样的话记录在哪里？如果不是那么代码有什么问题？

Grails 3.x- GORM - inList失败，成员以下划线（_）开头
