Grails 从域验证器获取会话变量

我确信这是一个常见的情况，但我还没有找到任何答案。我有一个会话范围的变量，用于保存当前登录的用户，我需要通过域对象中的自定义验证器来执行条件验证。有没有办法在验证器中从会话范围中获取当前用户，或者是否有其他方法可以做到这一点，请记住我希望能够从验证器返回特定字段的错误（例如if(isBlank(it))return ['blank','summary',Presentation];)

基本结构：

class MyDomain 
{
    String aProperty;
    static constraints =
    {
        aProperty(validator:{
        if(isAdmin())return true;
        if(isBlank(it))return ['blank','summary',Presentation];
        })
    }
}

Im sure this is a common scenario, but I haven't found any answers. I have a session-scoped variable that holds the currently signed in user and I need to perform conditional validation by way of a custom validator in a domain object. Is there a way to get the the current user from the session scope while in a validator, or is there perhaps another way to do this, keeping in mind that I want to be able to return the errors for specific fields from my validator(e.g. if(isBlank(it))return ['blank','summary',Presentation];)

basic struture:

class MyDomain 
{
    String aProperty;
    static constraints =
    {
        aProperty(validator:{
        if(isAdmin())return true;
        if(isBlank(it))return ['blank','summary',Presentation];
        })
    }
}
