这就是我犯的错误

我不确定我是否理解您的确切问题,因此我将为您列出两种不同的方案和解决方案:
考虑Config.groovy中的以下两个条目
feedbackAddress="xyz@abcdefg.com"
blogs = {groupName->
if(groupName == 'IT') {
//return blog URLs for IT folks
} else if(groupName == 'UX') {
//return blog URLs for UX folks
} else {
//return others
}
}
案例1:使用字符串作为配置名称。您可以访问反馈地址,如:
def feedbackAddress = grailsApplication.config["feedbackAddress"]
案例2:将参数传递给配置。您可以列出特定组的博客,如:
def groupName = "IT"
grailsApplication.config.blogs(groupName) //this will give you whatever's defined in the IT block of config.
