我如何用 GSON 解析这个？因为这个以数字“1”和“2”开头。我已经为以 entity_id 开头的对象创建了一个对象，并且当我删除了外部 json（其中包含“1”）时它正在工作。

但我想解析这一大堆代码。那么我应该怎么做来解析“1”和“2”呢？像 String id 和 List innerobjects 之类的东西？

Map对奇数"1", "2", ...对象使用 a ：

Map<String, Order> map = gson.fromJson(json, Map.class);

我找到了另一个解决方案。

GsonBuilder builder = new GsonBuilder();
builder.setFieldNamingStrategy( new FieldNamingStrategy() {
   @Override
   public String translateName( Field field ) {
       if( field.getName().equals( "myNewVariableName" ) ) {
          return "1";
       } else {
          return field.getName();
       }
}
} );
Gson gson = builder.create();
MyCustomClass queryResult = gson.fromJson( json, MyCustomClass.class );

现在写下我在示例“MyCustomClass”中调用的自定义 gson 类。添加一个名为“myNewVariableName”的字段。如果 Gson 序列化或反序列化 json 或您的自定义类，它使用 FieldNamingStrategy 并将您的字段“myNewVariableName”替换为“1”。通过这种方式，您可以减少自己的完整解析，并为您重用 gson 的强大功能，例如“entity_id”等格式正确的字段名称。
