在grails中创建动态变量名

我对动态变量名有问题

我有像这样的表单参数

ip1
ip2
ip3
dns1
dns2
...

我知道有多少，但我不知道如何在控制器中创建变量名

def ipcount = params.count
    for (i = 1; i = ipcount ; i++ ){
         def systems = new Ip() 
         systems.inetAddress = params.ip+${i}  <---- How do I create these variable name?
                 ....

def ipcount=params.count
对于（i=1；i=ipcount；i++）{
def系统=新Ip（）
systems.inetAddress=params.ip+${i}只需将它们用双引号括起来：

def ipcount = params.int( 'count' )
def systemsList = (1..ipcount).collect { i ->
    def systems = new Ip() 
    systems.inetAddress = params."ip${i}"
    ...
    systems
}

请用双引号将它们括起来：

def ipcount = params.int( 'count' )
def systemsList = (1..ipcount).collect { i ->
    def systems = new Ip() 
    systems.inetAddress = params."ip${i}"
    ...
    systems
}
