Validation Groovy 2.4.4命令对象-重用验证器闭包

假设我有以下命令：

@Validateable
class MyCommand {
    String cancel_url
    String redirect_url
    String success_url

    static constraints = {
        cancel_url nullable: false, validator: { url, obj ->
            //some specific validation
            //some common url validation
        }
        redirect_url nullable: false, validator: { url, obj ->
            //some specific validation
            //some common url validation
        }
        success_url nullable: false, validator: { url, obj ->
            //some specific validation
            //some common url validation
        }
    }
}

假设我想对任何URL字段执行一些常见的验证（例如，检查是否允许该域）。什么样的语法可以将这个常见的验证代码分解成一个单独的函数，而不是在每个验证闭包中放入相同的块？

您是否尝试从几个trait继承（或者说实现）您的命令

Trait CancelComponentCommand {
    String cancelUrl

    static constraints = {
        cancelUrl validator: { url, obj ->
            //some specific validation
            //some common url validation
        }
    }
}

Trait RedirectComponenCommand {
    String redirectUrl

    static constraints = {
            redirectUrl validator: { url, obj ->
            //some specific validation
            //some common url validation
        }
    }
}

@Validateable
class MyCommand implements CancelComponentCommand, RedirectComponenCommand {

}

PS无需设置

可空：false

，默认为false。另外，如果使用camelCase编写字段，代码的可读性会更好。
