将枚举列表传递给标准 [英] Passing Enum List to Criteria

问题描述

我有一个域名付款

$ p $ 类别付款{
字符串名称
PaymentType paymentType
}


PaymentType是一个ENUM

搜索特定付款类型的所有付款很简单

  def结果= Payment.createCriteria.list ='（'paymentType'，PaymentType.valueOf（params.paymentType））
'
'b 
 
 
 
 
 
当我想要搜索所有支付方式时，如何处理多于一种支付类型的情况，例如params.paymentType是数组？ >解决方案

如果paymentType是一个数组，您可以这样做：



  def results = Payment.createCriteria（）。list {$'b'in'（'paymentType'，params.paymentType.collect {PaymentType.valueOf（it）}）
} 
  




I have a domain Payment

class Payment {
  String name
  PaymentType paymentType
}

PaymentType is an ENUM

to search all payments of a particular payment type is simple

def results = Payment.createCriteria.list = {
  'in' ('paymentType', PaymentType.valueOf(params.paymentType))
}

how can i handle the situation when I want to search all Payments against more then one payment type i.e. if params.paymentType is an array?

解决方案

If paymentType is an array, you can do something like this:

def results = Payment.createCriteria().list {
   'in' ('paymentType', params.paymentType.collect{PaymentType.valueOf(it)})
}
