如何关联我在android应用程序中获得的各个json数据？

在我的android应用程序中，我正在访问外部PostgreSQL数据库，我能够获取json数据，但在这里，我正在访问三个通过id相关的表。我分别获取这些表的json数据。现在我的问题是如何通过我的应用程序中的关系从三个表中获取数据？在我的应用程序中，我使用的是Spring Rest API

通过此链接，我访问第一个表

http://localhost:443/seis/productTemplateController/getproductTemplate

我得到了这样的json数据

首先，我建议您使用Gson将Json解析为ProductTemplate、Account和Partner类。那么您需要id字段来建立它们之间的连接吗
