Groovy 用另一个闭包扩展闭包

我正在尝试使用

ConfigSlurper

解析Groovy文件，这些文件将用作Java程序的配置文件

我希望支持具有基本属性的分层配置，如果需要，可以覆盖这些基本属性。我认为闭包是一种很好的表示方法，但我遇到了一个小问题

通过将基本闭包左移到子闭包上，我可以将基本密钥传播到子配置：

base {
    baseKey = "All closures that compose from this closure will have this key"
}

config1 {
    config1only = "value"
}
config1 << base

config2 {
    config2only = "another value"
}
config2 << base

太好了！但是，当我试图覆盖一个

config

闭包中的基键时，基闭包中的基键似乎优先，这不是我所期望的。资料来源如下：

base {
    baseKey = "All closures that compose from this closure will have this key"
    overiddenKey = "base"
}

config1 {
    config1only = "value"
    overiddenKey = "override1"
}
config1 << base

config2 {
    config2only = "another value"
    overiddenKey = "override2"
}
config2 << base

我试着换到右班，但我总是出错：

Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: groovy.util.ConfigObject.leftShift() is applicable for argument types: (script15162997138121381677545$_run_closure1) values: [script15162997138121381677545$_run_closure1@3d246ea3]

这可能是因为我对groovy闭包的工作原理了解有限，所以如果有任何帮助，我将不胜感激

更新：

看来我已经通过使用

base.clone（）

找到了我想要的东西：

这正是我所期望的：

base {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='base'
}
config1 {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='base'
    config1only='value'
}
config2 {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='override2'
    config2only='another value'
}

但是

configN

定义之前的整个

configN=base.clone（）。有没有办法让我把它清理一下？或者使用groovy不是最好的选择吗？
这就是您想要的吗

输入：

base {
    baseKey = "All closures that compose from this closure will have this key"
    overiddenKey = "base"
}

config1 << base
config1 {
    config1only = "value"
    overiddenKey = "override1"
}
config2 << base
config2 {
    config2only = "another value"
    overiddenKey = "override2"
}

“有什么方法可以让我稍微整理一下吗？”-为什么不干脆
config1是的，哈哈，我真不敢相信我没有想到这一点。
base {
    baseKey = "All closures that compose from this closure will have this key"
    overiddenKey = "base"
}

config1 = base.clone()
config1 {
    config1only = "value"
}

config2 = base.clone()
config2 {
    config2only = "another value"
    overiddenKey = "override2"
}

base {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='base'
}
config1 {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='base'
    config1only='value'
}
config2 {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='override2'
    config2only='another value'
}

base {
    baseKey = "All closures that compose from this closure will have this key"
    overiddenKey = "base"
}

config1 << base
config1 {
    config1only = "value"
    overiddenKey = "override1"
}
config2 << base
config2 {
    config2only = "another value"
    overiddenKey = "override2"
}

base {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='base'
}
config1 {
    baseKey='All closures that compose from this closure will have this     key'
    overiddenKey='override1'
    config1only='value'
}
config2 {
    baseKey='All closures that compose from this closure will have this key'
    overiddenKey='override2'
    config2only='another value'
}
