基于Spring Boot的疫苗接种预约系统设计与实现
一、项目背景
随着疫苗接种工作的重要性不断提升,越来越多的地区开始采用信息化手段来提升接种效率。基于Spring Boot的疫苗接种预约系统旨在为广大用户提供一个友好的预约平台,实现疫苗接种的在线预约、查询和管理功能。通过该系统,可以有效避免接种现场的拥挤,提升接种效率,保障公众健康。
二、系统需求分析
该疫苗接种预约系统主要分为几个模块:
- 用户管理模块:用户注册、登录、信息修改等功能。
- 疫苗信息管理模块:疫苗信息的添加、修改、删除与查询。
- 预约管理模块:用户可以在线预约接种时间,查询自己的预约记录。
- 管理员管理模块:管理员可以查看所有用户预约情况,处理预约请求。
三、技术选型
本系统采用Spring Boot作为后台框架,数据库使用MySQL,前端采用Thymeleaf模板引擎进行页面渲染。项目结构如下:
src
└── main
├── java
│ └── com
│ └── example
│ └── vaccine
│ ├── controller
│ ├── entity
│ ├── repository
│ ├── service
│ └── VaccineApplication.java
└── resources
├── application.properties
└── templates
四、系统设计
1. 数据库设计
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(50) NOT NULL UNIQUE,
password VARCHAR(255) NOT NULL,
phone VARCHAR(15) NOT NULL
);
CREATE TABLE vaccines (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(50) NOT NULL,
description TEXT
);
CREATE TABLE appointments (
id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT NOT NULL,
vaccine_id INT NOT NULL,
appointment_time DATETIME NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (vaccine_id) REFERENCES vaccines(id)
);
2. 实体类设计
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String username;
private String password;
private String phone;
// getters and setters
}
@Entity
public class Vaccine {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
private String description;
// getters and setters
}
@Entity
public class Appointment {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private Long userId;
private Long vaccineId;
private LocalDateTime appointmentTime;
// getters and setters
}
3. 控制器设计
@Controller
@RequestMapping("/appointments")
public class AppointmentController {
@Autowired
private AppointmentService appointmentService;
@PostMapping("/book")
public String bookAppointment(@RequestParam Long userId,
@RequestParam Long vaccineId,
@RequestParam String appointmentTime) {
appointmentService.bookAppointment(userId, vaccineId, appointmentTime);
return "redirect:/appointments/list";
}
@GetMapping("/list")
public String listAppointments(Model model, @SessionAttribute("userId") Long userId) {
List<Appointment> appointments = appointmentService.getAppointmentsByUserId(userId);
model.addAttribute("appointments", appointments);
return "appointment/list";
}
}
4. 服务层设计
@Service
public class AppointmentService {
@Autowired
private AppointmentRepository appointmentRepository;
public void bookAppointment(Long userId, Long vaccineId, String appointmentTime) {
Appointment appointment = new Appointment();
appointment.setUserId(userId);
appointment.setVaccineId(vaccineId);
appointment.setAppointmentTime(LocalDateTime.parse(appointmentTime));
appointmentRepository.save(appointment);
}
public List<Appointment> getAppointmentsByUserId(Long userId) {
return appointmentRepository.findByUserId(userId);
}
}
五、总结
基于Spring Boot的疫苗接种预约系统通过合理的架构设计与模块划分,实现了用户及疫苗的管理、预约功能。未来可以考虑增加短信通知、疫苗接种记录生成等功能,进一步提升系统的实用性和用户体验。通过此项目的设计与实现,不仅提升了自己的技术能力,也对信息化在公共卫生领域的重要性有了更深刻的理解。
