java根据给定的键对JSON字符串进行动态排序

Question

我想根据一些键对JSON字符串进行排序。我的JSON可以有多个嵌套数组。有没有对json进行排序的库/工具

我收到的JSON对象，key是可选的。例如，在下面的请求中，我们第一次使用名称对参与者数组进行排序，然后第二次使用第二个参与者中不存在的子名称进行排序。我还想通过动态发送密钥进行排序。在下面的示例中，我使用了名称和子名称，同样，我应该能够发送任何密钥和排序

例如：

{
  "Actors": [
    {
      "name": "Tom Cruise",
      "age": 56,
      "Born At": "Syracuse, NY",
      "Birthdate": "July 3, 1962",
      "photo": "https://jsonformatter.org/img/tom-cruise.jpg",
      "wife": null,
      "weight": 67.5,
      "hasChildren": true,
      "hasGreyHair": false,
    },
    {
      "name": "Robert Downey Jr.",
      "age": 53,
      "Born At": "New York City, NY",
      "Birthdate": "April 4, 1965",
      "photo": "https://jsonformatter.org/img/Robert-Downey-Jr.jpg",
      "wife": "Susan Downey",
      "weight": 77.1,
      "hasChildren": true,
      "hasGreyHair": false,
      "children": [
                   {
                     "name":"Tom",
                      "age":15
                   },
                  {
                     "name":"Jerry"
                     "age":17
                   }
      ]
    }
  ]
}

首先基于名称进行排序，然后基于排序子项名称数组进行排序

输出：

{
  "Actors": [
    {
      "name": "Robert Downey Jr.",
      "age": 53,
      "Born At": "New York City, NY",
      "Birthdate": "April 4, 1965",
      "photo": "https://jsonformatter.org/img/Robert-Downey-Jr.jpg",
      "wife": "Susan Downey",
      "weight": 77.1,
      "hasChildren": true,
      "hasGreyHair": false,
      "children": [
                   {
                     "name":"Jerry"
                     "age":16
                   },
                  {
                     "name":"Tom"
                     "age":15
                   }
      ]
    },
 {
      "name": "Tom Cruise",
      "age": 56,
      "Born At": "Syracuse, NY",
      "Birthdate": "July 3, 1962",
      "photo": "https://jsonformatter.org/img/tom-cruise.jpg",
      "wife": null,
      "weight": 67.5,
      "hasChildren": true,
      "hasGreyHair": false,
    },
  ]
}

我希望在不创建任何Iava对象的情况下实现这一点。我无法控制基于输入输出的JSON字符串，JSON总是变化的
