可以将ResponseData类中的Data属性改为泛型类型T，然后在使用ResponseData时指定T的具体类型，例如：

@Data public class ResponseData { private int code; private String msg; private T data; }

然后在使用时可以这样：

ResponseData<List> responseData = new ResponseData<>(); responseData.setData(checkDataList);

或者这样：

ResponseData responseData = new ResponseData<>(); responseData.setData(otherData);
