如何使用SpringBoot解析JSON数组

Question

{"errcode":0,"result":[{"check_date_time":"2021-08-27 17:57:30","check_status":"Checked","check_type":"OnDuty","corp_id":"ding7c748955d913770335c2f4657eb6378f","gmt_create":"2021-08-27 17:57:31","gmt_modified":"2021-08-27 17:57:31","group_id":-1,"id":235069117132,"is_rest":"N","real_plan_time":"2021-08-27 17:57:30","user_id":"242157225634238654","work_date":"2021-08-27 00:00:00"}],"success":true,"request_id":"8kus66o51zb2"}

之前的

{"errcode":0,"result":{"approve_list":[],"attendance_result_list":[{"check_type":"OffDuty","class_id":214655132,"group_id":240975087,"location_method":"ATM","location_result":"Normal","plan_check_time":"2021-07-14 17:00:00","plan_id":217863022888,"record_id":67835293281,"source_type":"ATM","time_result":"Normal","user_address":"前台","user_check_time":"2021-07-14 17:15:35"},{"check_type":"OnDuty","class_id":214655132,"group_id":240975087,"location_method":"ATM","location_result":"Normal","plan_check_time":"2021-07-14 08:00:00","plan_id":217863022887,"record_id":67956355229,"source_type":"ATM","time_result":"Normal","user_address":"前台","user_check_time":"2021-07-14 07:58:52"}],"check_record_list":[{"record_id":67835293281,"source_type":"ATM","user_check_time":"2021-07-14 17:15:35","valid_matched":true},{"record_id":67956355229,"source_type":"ATM","user_check_time":"2021-07-14 07:58:52","valid_matched":true}],"class_setting_info":{"rest_time_vo_list":[{"rest_begin_time":14400000,"rest_end_time":18000000}]},"corpId":"ding7c748955d913770335c2f4657eb6378f","userid":"51191","work_date":"2021-07-14 09:00:00"},"success":true,"request_id":"10hbita0g2902"}

然后用了两种办法，一种因为缺少Object名导致不知道怎么单独建list，从而无法反序列化。第二种直接创建LIST导致无法正常CAST

Answer 1

public class ToResultDTO {
    private Integer errcode;
    private ArrayList<Item> result;
    private String success;
    private String request_id;

    static class Item{
        private String check_date_time;
        private String check_status;
        private String check_type;
        private String corp_id;
        private String gmt_create;
        private String gmt_modified;
        private String group_id;
        private String id;
        private String is_rest;
        private String real_plan_time;
        private String user_id;
        private String work_date;
    }

}
