如何使用java在另一个json中转换json

我有这样一个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"
  }

'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'
            }

我需要将其转换为json结构，如下所示：

{
    "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"
  }

'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'
            }

简单地说，我需要按“部门1”对数据进行分组。

尝试使用gson或Jackson等工具将json映射到Java对象。请参阅了解如何在java中按属性对对象进行分组。请尝试使用gson或Jackson等工具将json映射到java对象。请参阅了解如何在java中按属性对对象进行分组。
