使用對象映射器解析復雜的JSON

Question

I am trying to parse complex JSON response using REST template.

對於上面的嘗試找出POJO的響應，我嘗試了幾個POJO層次結構來解析這些Json無法找出來的東西，有人可以建議我POJO來解析它嗎？

實際上，JSON響應具有包含對象的JSON數組列表，還有一個沒有對象的數組，並且很難使用對象映射器將任何映射庫映射到該響應的數組，但是我們能否獲得幫助來構建此響應的對象模型。

Answer 1

您有三種選擇：

1. 請與API提供程序聯系，以了解API的Swagger / OpenAPI定義。 如果有的話，您可以使用Swagger Codegen生成代碼。

2. 查找API文檔，並根據手工定義的模型編寫Java類。

3. 如果您沒有時間處理第2點，則可以使用quicktype ，它直接從JSON示例生成代碼。
