访问grails中域类中的属性文件

Question

我有一个属性文件，其中包含以下参数

 PAGINATION1=10
 PAGINATION2=20

在我的config.groovy文件中，我设置了

  grails.config.locations = ["classpath:default.properties","file:"+ fullPath]

读取属性文件值。

我可以使用

访问控制器中的属性值

 grailsApplication.config.PAGINATION1

工作正常。

我按照以下链接访问属性文件

http://burtbeckwith.com/blog/?p=993&cpage=1

 class  Pagination  {

   int paginationNumber;

   static someMethod() {
    def grailsApplication = new Pagination().domainClass.grailsApplication
    def config = grailsApplication.config
    return config
}

    static constraints={
    def grailsConfig=someMethod();
    paginationNumber inList:[grailsConfig.PAGINATION1,'20','30','40']
}

}

但是我收到以下错误。
