FeignClient List＜xxObject＞ java.lang.ClassCastException

bug场景：
1、使用FeignClient调用业务系统获得List
2、遍历List执行业务逻辑

List xxObecjtLsit = feginClient.getList();
for (xxObject obecjt : xxObecjtLsit) {
	.......
}

报错信息：

java.lang.ClassCastException: class com.alibaba.fastjson.JSonObject cannot be cast to class com.flex.ops.model.vo.xxObecjt (com.alibaba.fastjson.JSonObject and com.flex.ops.model.vo.xxObecjt are in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @21a5fd96)

本机开发环境和测试环境都没有问题，查看了生产的数据信息和本地的数据结构一致

解决办法：转成jsonString在转回去

String jsonString = JSON.toJSONString(list);
List finalList = JSON.parseArray(jsonString, xxObject.class);

虽然不知道为啥，但是可以解决这个问题，等以后能力提升在研究到底是因为啥吧。。。。
