HttpMessageNotreadableException：无法使用Spring boot和Android读取JSON：无法识别的字段

Question

我正在开发与我的服务器通信的web应用程序。这种通信是通过Spring框架和react JS完成的。我正在发送一个请求，请求我的服务器读取json，但是我得到了这个错误

错误反应控制台：

未捕获（在promise中）错误：请求失败，状态代码为400

如上所述-不能有2个或更多的@RequestBody。我建议创建一个包装类，它将保存您的这两个类中的这些参数。也摆脱这个‘逻辑’从您的控制器层...把这些如果扔掉...考虑使用vavr库中的模式匹配，因为策略模式似乎在那里被过度使用
