智慧医疗预约平台：基于JSP的医院挂号系统深度解析

在医疗信息化快速发展的今天，传统医院窗口挂号模式已无法满足现代医疗服务的需求。患者排队耗时、医疗资源分配不均、就诊体验差等问题日益突出。智慧医疗预约平台应运而生，采用JSP+Servlet+JavaBean的MVC架构，构建了一套完整的在线预约挂号解决方案。

系统架构与技术栈

该系统采用经典的三层架构模式，表现层使用JSP动态页面技术，业务逻辑层由Servlet控制器实现，数据持久化层通过JDBC连接MySQL数据库。这种分层架构确保了代码的可维护性和系统的可扩展性。

核心Servlet控制器示例：

@WebServlet("/AppointmentServlet")
public class AppointmentServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) 
            throws ServletException, IOException {
        String action = request.getParameter("action");
        AppointmentDAO appointmentDAO = new AppointmentDAO();
        
        switch(action) {
            case "book":
                String patientId = request.getParameter("patientId");
                String doctorId = request.getParameter("doctorId");
                String appointmentDate = request.getParameter("appointmentDate");
                String timeSlot = request.getParameter("timeSlot");
                
                Appointment appointment = new Appointment();
                appointment.setPatientId(patientId);
                appointment.setDoctorId(doctorId);
                appointment.setAppointmentDate(java.sql.Date.valueOf(appointmentDate));
                appointment.setTimeSlot(timeSlot);
                appointment.setStatus("待就诊");
                
                boolean result = appointmentDAO.addAppointment(appointment);
                if(result) {
                    request.setAttribute("message", "预约成功！");
                } else {
                    request.setAttribute("error", "预约失败，请重试！");
                }
                break;
                
            case "cancel":
                String appointmentId = request.getParameter("appointmentId");
                boolean cancelResult = appointmentDAO.cancelAppointment(appointmentId);
                // 处理取消逻辑
                break;
        }
        request.getRequestDispatcher("appointment_result.jsp").forward(request, response);
    }
}

        List<Doctor> doctors = new ArrayList<>();
        String sql = "SELECT d.*, dep.department_name FROM doctors d " +
                    "LEFT JOIN departments dep ON d.department_id = dep.department_id " +
                    "WHERE 1=1";
        List<Object> params = new ArrayList<>();
        
        if (departmentId != null && !departmentId.isEmpty()) {
            sql += " AND d.department_id = ?";
            params.add(departmentId);
        }
        if (doctorName != null && !doctorName.isEmpty()) {
            sql += " AND d.doctor_name LIKE ?";

                        return false;
                    }
                    appointment.setStatus("已取消");
                    // 释放号源
                    scheduleDAO.releaseTimeSlot(
                        appointment.getDoctorId(),
                        appointment.getAppointmentDate(),
                        appointment.getTimeSlot(),
                        conn
                    );
                    break;
                    
                default:
                    return false;
            }
            
            boolean success = appointmentDAO.updateAppointment(appointment, conn);
            if (success) {
                conn.commit();
                return true;
            } else {
                conn.rollback();
                return false;
            }
        } catch (SQLException e) {

public class ScheduleValidator {
    public ValidationResult validateSchedule(DoctorSchedule newSchedule) {
        ValidationResult result = new ValidationResult();
        
        // 检查时间有效性
        if (newSchedule.getWorkDate().before(new Date())) {
            result.addError("排班日期不能早于当前日期");
            return result;
        }
        
        // 检查同一医生时间冲突
        List<DoctorSchedule> existingSchedules = 
            scheduleDAO.getSchedulesByDoctorAndDate(
                newSchedule.getDoctorId(), 
                newSchedule.getWorkDate()
            );
        
        for (DoctorSchedule existing : existingSchedules) {
            if (isTimeOverlap(existing.getTimeSlot(), newSchedule.getTimeSlot())) {
                result.addError("该时间段已有排班安排");
                break;
            }
        }
        
        // 检查单日排班总数限制
        if (exceedingDailyLimit(newSchedule)) {
            result.addError("单日排班总数超过限制");
        }
        
        return result;
    }
    
    private boolean isTimeOverlap(String slot1, String slot2) {
        // 实现时间段重叠检测逻辑
        String[] time1 = slot1.split("-");
        String[] time2 = slot2.split("-");
        
        LocalTime start1 = LocalTime.parse(time1[0]);
        LocalTime end1 = LocalTime.parse(time1[1]);
        LocalTime start2 = LocalTime.parse(time2[0]);
        LocalTime end2 = LocalTime.parse(time2[1]);
        
        return !(end1.isBefore(start2) || start1.isAfter(end2));
    }
}

患者个人中心

患者可以查看预约记录、管理个人信息、修改密码等，提供完整的自助服务功能。

查看预约信息

患者服务实现：

public class PatientService {
    public PatientProfile getPatientProfile(String patientId) {
        PatientProfile profile = new PatientProfile();
        
        // 获取基本信息
        Patient patient = patientDAO.getPatientById(patientId);
        profile.setPatient(patient);
        
        // 获取预约记录
        List<Appointment> appointments = 
            appointmentDAO.getAppointmentsByPatientId(patientId);
        profile.setAppointments(appointments);
        
        // 统计信息
        Map<String, Object> statistics = new HashMap<>();
        statistics.put("totalAppointments", appointments.size());
        statistics.put("completedAppointments", 
            appointments.stream().filter(a -> "已就诊".equals(a.getStatus())).count());
        statistics.put("pendingAppointments",
            appointments.stream().filter(a -> "待就诊".equals(a.getStatus())).count());
        
        profile.setStatistics(statistics);
        return profile;
    }
}

实体模型设计

系统采用面向对象的设计理念，核心实体模型关系清晰，支持复杂的业务逻辑处理。

核心实体类定义：

public class Appointment {
    private String appointmentId;
    private String patientId;
    private String doctorId;
    private Integer departmentId;
    private Date appointmentDate;
    private String timeSlot;
    private String appointmentNumber;
    private BigDecimal fee;
    private String status;
    private Date createTime;
    private Date updateTime;
    private String cancelReason;
    private String symptomsDescription;
    private String diagnosisResult;
    private String prescriptionInfo;
    
    // 关联对象
    private Patient patient;
    private Doctor doctor;
    private Department department;
    
    // 业务方法
    public boolean canBeCanceled() {
        return "待支付".equals(status) || "待就诊".equals(status);
    }
    
    public boolean isExpired() {
        return appointmentDate.before(new Date()) && "待就诊".equals(status);
    }
}

系统优化与扩展方向

性能优化策略

功能扩展建议

  1. 智能推荐系统：基于患者历史就诊记录和症状描述，智能推荐合适的科室和医生
  2. 移动端适配：开发响应式设计或独立的移动APP，提升移动用户体验
  3. 支付集成：集成第三方支付平台，支持在线支付挂号费用
  4. 消息推送：实现预约提醒、停诊通知等消息的短信/微信推送功能
  5. 数据分析平台：构建数据看板，为医院管理提供决策支持

技术架构升级

  1. 微服务化改造：将单体应用拆分为用户服务、预约服务、排班服务等微服务
  2. 前后端分离：采用Vue.js或React重构前端，RESTful API提供数据接口
  3. 容器化部署：使用Docker容器化部署，提高部署效率和系统稳定性
