网站每日签到功能设计 hibernate数据层框架

1：mysql数据库 表设计

CREATE TABLE `t_user_sign` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '签到表id',
  `user_id` bigint(20) DEFAULT NULL COMMENT '签到者id',
  `signcount` int(11) DEFAULT '0' COMMENT '连续签到次数',
  `count` int(11) DEFAULT '0' COMMENT '签到次数',
  `lastModifyTime` datetime DEFAULT NULL COMMENT '最后修改时间',
  `signHistoy` varchar(500) DEFAULT NULL COMMENT '签到历史时间 以逗号隔开',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
