使用Gson-Android的java动态Json解析

Question

我有一个json，如下所述

{
  "product": [
    {
      "classification": "abc",
      "ABC": [
        {
          "classification": "abc",
          "name": "abc new product one",
          "price": "10775.0000",
        },
        {
          "classification": "abc",
          "name": "abc new product two",
          "price": "12725.0000",
        }
      ]
    },
    {
      "classification": "def",
      "DEF": [
        {
          "classification": "def",
          "name": "def product one",
          "price": "728.0000",
        },
        {
          "classification": "def",
          "name": "def product two",
          "price": "1263.0000",
        },
      ]
    }
  ],
  "status": "OK",
  "message": "success"
}

在上面的json中，大写字母的键是动态的

(Ex: ABC, DEF)

。我创建了pojo类，如下所示：

    public class ProductResponse{

       private String status;
       private String message;
       private List<Products>;

       Getters And Setters
    }

    public class Products{

       private String classification;

    }

我正在努力写产品pojo类的下一部分，因为关键是大写字母

(Ex: ABC, DEF)

它们是动态的。我使用volley库获取数据，并使用gson库进行解析。请帮帮我

Answer 1

您不能有动态名称。原因是json中的名称需要链接到对象中的属性。 我建议您在json和模型中添加一个“classification”属性，如下所示：

{
  "type": "def",
  " results": [
    {
      "name": "def product one",
      "price": "728.0000",
    },
    {
      "name": "def product two",
      "price": "1263.0000",
    },
  ]
}



public final class ProductResponse{

       private String status;
       private String message;
       private List<Products> product = new Arraylist<>();

       // Getters And Setters
    }

    public final class Products{

       private String type; // type of product // ABC or DEF
       private List<Result> results = new Arraylist<>(); 

      // Getters And Setters
    }


     public final class Result{

       private String name;
       private String price;


     // Getters And Setters
    }

您的products类现在有一个与分类关联的结果列表

希望有帮助

你的问题是动态键，我发现它不是动态的。如我所见，对于product数组中的每个元素，classification键的值是下一个键。唯一的区别是它们是大写的

{
  "classification": "def",
  "DEF": [
    {
      "classification": "def",
      "name": "def product one",
      "price": "728.0000",
    },
    {
      "classification": "def",
      "name": "def product two",
      "price": "1263.0000",
    },
  ]
}

如中所示，这里是"classification": "def"，下一个键是DEF。这里我要做的是获取classification键的值，将字符串中的所有字母大写，然后将其用作key
