如何在java中转换另一个json中的json

Question

我有一个像这样的json：

{
    "name": "Team Wolf",
    "www": "http://www.teamwolf.qqq",
    "department": "department1",
    "team1": "team1"
  },
  {
    "name": "Team Fox",
    "www": "http://www.teamfox.qqq",
    "department": "department1",
    "team2": "team2"
  },
 {
    "name": "Team Falcon",
    "www": "http://www.teamfalcon.qqq",
    "department": "department1",
    "team3": "team3"
  }

我需要在像这样结构的json中对其进行转换：

'department1': {
            'team1': {
              'name':'Team Wolf',
              'www': 'http://www.teamwolf.qqq'
            },
            'team2': {
              'name':'Team Fox',
              'www': 'http://www.teamfox.qqq'
            },
            'team3': {
              'label':'Team Falcon',
              'www': 'http://www.teamfalcon.qqq'
            }

简单来说，我需要按照部门1＆＃39;对数据进行分组。 任何建议都会非常感激。
