如何在grails中创建条件createCriteria（）

Question

我有一个域类反馈

class Feedback{
    String name
    String email
    Date createdOn
    Boolean isMailSent
}

I want to fetch all feedbacks with the condition as below 

1) isMailSent ==  false

2) (createdOn - cuurent time) >= 15 minutes 

如何在createCriteria（）方法中编写这些条件。

我在这里尝试了什么

def feedbackList = Feedback.createCriteria().list(
        ) {
            eq('isMailSent ',  false)
            /** here condition (createdOn - cuurent time) >= 15 minutes **/
       }

以下是如何完成此操作的示例。我把它做得稍微冗长，所以它更容易阅读。

import groovy.time.TimeCategory

def now = new Date()
def fifteenMinutesAgo = null
use(TimeCategory) {
    fifteenMinutesAgo = now - 15.minutes
}

def feedbackList = Feedback.createCriteria().list() {
  eq('isMailSent', false)
  le('createdOn', fifteeenMinutesAgo)
}
