SpringBoot Mybatis Thymeleaf 在线预约挂号系统 写一套java代码

很抱歉，由于时间和篇幅的限制，我无法在这里提供完整的在线预约挂号系统的Java代码。不过，我可以为您提供一些示例代码，帮助您更好地理解该系统的实现方式。

1. 注册功能Controller代码：

@Controller
public class RegisterController {
    
    @Autowired
    private UserService userService;
    
    @GetMapping("/register")
    public String registerForm(Model model) {
        model.addAttribute("user", new User());
        return "register";
    }

    @PostMapping("/register")
    public String registerSubmit(@ModelAttribute User user, Model model) {
        if(userService.getUserByUsername(user.getUsername()) != null) {
            model.addAttribute("error", "用户名已存在");
            return "register";
        }
        userService.addUser(user);
        return "redirect:/login";
    }
}

2. 医院管理Controller代码：

@Controller
@RequestMapping("/admin")
public class HospitalAdminController {
    
    @Autowired
    private HospitalService hospitalService;
    
    @GetMapping("/hospitals")
    public String hospitalList(Model model) {
        List<Hospital> hospitals = hospitalService.getAllHospitals();
        model.addAttribute("hospitals", hospitals);
        return "hospital_list";
    }
    
    @GetMapping("/hospitals/new")
    public String newHospitalForm(Model model) {
        model.addAttribute("hospital", new Hospital());
        return "hospital_form";
    }
    
    @PostMapping("/hospitals/new")
    public String newHospitalSubmit(@ModelAttribute Hospital hospital) {
        hospitalService.addHospital(hospital);
        return "redirect:/admin/hospitals";
    }
    
    @GetMapping("/hospitals/{id}")
    public String hospitalDetail(@PathVariable Long id, Model model) {
        Hospital hospital = hospitalService.getHospitalById(id);
        model.addAttribute("hospital", hospital);
        return "hospital_detail";
    }
    
    @GetMapping("/hospitals/{id}/edit")
    public String editHospitalForm(@PathVariable Long id, Model model) {
        Hospital hospital = hospitalService.getHospitalById(id);
        model.addAttribute("hospital", hospital);
        return "hospital_form";
    }
    
    @PostMapping("/hospitals/{id}/edit")
    public String editHospitalSubmit(@ModelAttribute Hospital hospital) {
        hospitalService.updateHospital(hospital);
        return "redirect:/admin/hospitals";
    }
    
    @GetMapping("/hospitals/{id}/delete")
    public String deleteHospital(@PathVariable Long id) {
        hospitalService.deleteHospitalById(id);
        return "redirect:/admin/hospitals";
    }
}

3. 挂号功能Controller代码：

@Controller
public class AppointmentController {
    
    @Autowired
    private AppointmentService appointmentService;
    
    @GetMapping("/appointments")
    public String appointmentList(Model model) {
        List<Appointment> appointments = appointmentService.getAllAppointments();
        model.addAttribute("appointments", appointments);
        return "appointment_list";
    }
    
    @GetMapping("/appointments/new")
    public String newAppointmentForm(Model model) {
        model.addAttribute("appointment", new Appointment());
        return "appointment_form";
    }
    
    @PostMapping("/appointments/new")
    public String newAppointmentSubmit(@ModelAttribute Appointment appointment) {
        appointmentService.addAppointment(appointment);
        return "redirect:/appointments";
    }
    
    @GetMapping("/appointments/{id}")
    public String appointmentDetail(@PathVariable Long id, Model model) {
        Appointment appointment = appointmentService.getAppointmentById(id);
        model.addAttribute("appointment", appointment);
        return "appointment_detail";
    }
}

这些示例代码只是系统代码的一部分，但希望可以帮助您了解该系统的实现方式。
