Answer 1

你 debug 看一下 resdata 的实际类型是啥？
看结构是这个 arr[0].object.cgeneralhid

这是 json 字符串吧？ 可以用如下的工具类 ，将json 转成 List<Map<String, Object>> 形式

这是我写的json处理工具，包含【FastJson，Gson，json-lib】，里面有json串转 List的用法的，你去看看，不懂可以再问
https://github.com/Huazie/flea-framework/tree/main/flea-common/src/main/java/com/huazie/fleaframework/common/util/json

用法：

FastJsonUtils.toMapList(jsonString1)
GsonUtils.toMapList(jsonString1);
JsonUtils.toMapList(json1, "listMap");

如有帮助，欢迎采纳哈！

本人的开源项目，欢迎star支持下！！!
