SpringBoot+Mybatis实现接口的增查改，以及json中拼接json数组

本文主要是介绍SpringBoot+Mybatis实现接口的增查改，以及json中拼接json数组，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

增改查的评价表

DROP TABLE IF EXISTS `hpkh_police_review`;
CREATE TABLE `hpkh_police_review` (`id` int(11) NOT NULL AUTO_INCREMENT,`police_code` varchar(255) NOT NULL COMMENT '警员编号',`review_content` text COMMENT '点评内容',`timestamp_create` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '条目插入时间',`timestamp_modify` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT '最后一次修改条目时间戳',PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;INSERT INTO `hpkh_police_review` VALUES ('1', '209762', '今天辛苦了', '2020-05-26 11:22:01', '2020-05-26 11:22:01');
INSERT INTO `hpkh_police_review` VALUES ('2', '209762', '交通处罚很好', '2020-05-26 11:32:59', '2020-05-26 15:51:02');
INSERT INTO `hpkh_police_review` VALUES ('3', '017591', 'good', '2020-05-29 10:31:01', '2020-05-29 10:31:01');
