Groovy-更改嵌套地图中字符串的值 [英] Groovy - Change value of string in nested map

问题描述

我在Groovy中具有以下数据结构

I have the following data structure in Groovy

我想知道Groovy是否提供一种简单的方法(最好是单行)来遍历此数据结构，找到具有键"code"的TreeMap条目，并将trim()函数应用于其值.正如您在图像中看到的那样，键"code"的值是"1880".我要修剪它并使其成为"1880".谢谢.

I want to know if Groovy offers a simple way (Preferably one-liner) to iterate through this data structure, find the TreeMap entry which has a key of "code" and apply the trim() function to it's value. As you can see in the image, the value the key "code" is "1880 ". I want to trim it and make it "1880". Thanks.

推荐答案

我尝试过此方法，它对您的数据有效:

I tried this one and it worked for your data:

ageTypes = ageTypes.collect { it.each { it.value = (it.value instanceof String) ? it.value.trim() : it.value } }

UPD我相信可以通过某种方式对其进行优化.但是需要检查方法.

UPD I believe it can be optimized somehow. But need to check how.
