返回Groovy中的嵌套密钥 [英] Return Nested Key in Groovy

问题描述

我试图确定使用groovy返回嵌套键值的最佳方式。如果我有一张地图：

I am trying to determine the best way to return nested key values using groovy. If I have a map:

def map = [
   OrganizationName: 'SampleTest',
   Address: [
      Street: '123 Sample St',
      PostalCode: '00000',
   ]
]

有没有办法返回所有的键？ OrganizationName ， OrganizationURL ， Address.Street ， Address.PostalCode ？如果地图中没有地图，我可以使用map.keySet（）作为String []。我应该只是循环每个键，看看它是否是另一个地图的一个实例？

Is there a way to return all of the keys? OrganizationName, OrganizationURL, Address.Street, Address.PostalCode? If I didn't have an map within a map I could use map.keySet() as String[]. Should I just loop through each key and see if it is an instanceof another map?

推荐答案

没有这样的方法在groovy。您需要使用 instanceof 并可能是递归方法。

There's no such method You're looking for in groovy. You need to do it using instanceof and probably a recursive method.
