feign.FeignException$BadRequest: [400] during [GET] to [http://xxx/s/device/countDevices] [IProject#countDevices(DeviceParam)]: [{"timestamp":"2022-01-20T02:08:51.241+0000","status":400,"error":"Bad Request","message":"","path":"/s/device/countDevices"}]
出现类似错误，如果本地调试正常，且本地所有微服务都部署同个电脑，但服务器调试不正常且服务器各个微服务是部署在不同服务器，那么很大可能是 DeviceParam 类没有序列化，导致反序列化失败导致的
