将带有虚线键的平面图转换为分层json

本文介绍了将带有虚线键的平面图转换为分层json的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个散列图(未排序)，带有像这样的虚线键值对

I have a hashmap (unsorted) with dotted key value pairs like

person.adress.street=Fakestreet person.adress.nr=123 person.name=Mike person.adress.city=Springfield

我想将其转换为有效的json结构，例如:

And I would like to convert it into a valid json structure like:

{ "person" : { "name" : "Mike", "adress" : { "street" : "Fakestreet", "nr" : 123, "city" : "Springfield" } } }

我那里有一个库或一些标准的常规功能，还是需要手工制作这样的东西?

I there a library or some standard groovy functionallity out there or do I need to handcraft such a thing?

推荐答案

您可以使用groovy.util.ConfigSlurper 按照@cfrick的链接

或像这样缩短您的手工解决方案:

or shorten your hand-made solution like that:

Closure nester nester = { Map rslt, String key, val -> String[] keys = key.split( /\./, 2 ) if( !rslt.containsKey( keys[ 0 ] ) ) rslt[ keys[ 0 ] ] = [:] if( 2 == keys.length ) nester rslt[ keys[ 0 ] ], keys[ 1 ], val else rslt[ key ] = val rslt } def d = [ 'person.name':'Mike', 'person.adress.street':'Fakestreet', 'person.adress.nr':123, 'person.adress.city':'Springfield', 'aaa':'bbb' ] def tree = d.inject [:], nester.trampoline() assert '{"person":{"name":"Mike","adress":{"street":"Fakestreet","nr":123,"city":"Springfield"}},"aaa":"bbb"}' == JsonOutput.toJson( tree )
