一、语言和环境

1. 实现语言：JAVA语言。
2. 环境要求：MyEclipse/Eclipse + Tomcat + MySQL。
3. 使用技术：
 Spring MVC + Spring + MyBatis 或 JSP + Servlet + JavaBean + JDBC。


二、实现效果

实现能够对患者姓名，医师类别、科室的模糊查询，用户点击核销以后状态变为已就诊。
点击挂号实现基本信息的添加

三、实现代码

数据库：

SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for tb_patient-- ----------------------------DROP TABLE IF EXISTS `tb_patient`;CREATE TABLE `tb_patient` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(50) DEFAULT NULL, `sex` varchar(10) DEFAULT NULL, `age` int(11) DEFAULT NULL, `phone` varchar(20) DEFAULT NULL, `department` varchar(50) DEFAULT NULL, `type` varchar(50) DEFAULT NULL, `price` decimal(9,2) DEFAULT NULL, `state` int(11) DEFAULT NULL, `register_time` datetime DEFAULT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;-- ------------------------------ Records of tb_patient-- ----------------------------INSERT INTO `tb_patient` VALUES ('1', '张蕾', '女', '12', '13895463212', '儿科', '专家医师', '25.00', '1', '2021-07-18 12:23:00');INSERT INTO `tb_patient` VALUES ('2', '刘德明', '男', '28', '13345623215', '骨科', '普通医师', '8.00', '0', '2021-07-18 12:23:00');INSERT INTO `tb_patient` VALUES ('3', '李将军', '男', '38', '13578064788', '内科', '专家医师', '25.00', '1', '2021-07-17 12:23:00');INSERT INTO `tb_patient` VALUES ('4', '张佩佩', '女', '44', '18214217246', '外科', '副主任医师', '17.00', '0', '2021-07-16 12:23:00');INSERT INTO `tb_patient` VALUES ('5', '程聪明', '男', '29', '13652645964', '骨科', '副主任医师', '17.00', '0', '2021-08-08 16:21:52');
