基于ssm+mysql+oracle宿舍管理，快醒醒吧

快醒醒吧，宿舍管理系统的开发涉及到的技术栈包括SSM（Spring+SpringMVC+MyBatis）框架，MySQL数据库和Oracle数据库。以下是一个简化的功能列表，以及如何开始构建宿舍管理系统的示例代码。

1. 用户登录与权限管理：

@Controller
public class LoginController {
    @Autowired
    private UserService userService;
 
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(@RequestParam String username, @RequestParam String password,
                        HttpSession session, RedirectAttributes redirectAttributes) {
        User user = userService.login(username, password);
        if (user != null) {
            session.setAttribute("user", user);
            return "redirect:/home";
        } else {
            redirectAttributes.addFlashAttribute("error", "用户名或密码错误");
            return "redirect:/login";
        }
    }
    // ... 其他登录逻辑
}

2. 宿舍信息管理：

@Service
public class DormitoryService {
    @Autowired
    private DormitoryMapper dormitoryMapper;
 
    public void addDormitory(Dormitory dormitory) {
        dormitoryMapper.insert(dormitory);
    }
    // ... 其他宿舍管理方法
}

3. 学生管理：

@Service
public class StudentService {
    @Autowired
    private StudentMapper studentMapper;
 
    public void addStudent(Student student) {
        studentMapper.insert(student);
    }
    // ... 其他学生管理方法
}

4. 查看宿舍详情：

@Controller
public class DormitoryController {
    @Autowired
    private DormitoryService dormitoryService;
 
    @RequestMapping("/dormitory/{id}")
    public String getDormitory(@PathVariable("id") Long id, Model model) {
        Dormitory dormitory = dormitoryService.getDormitoryById(id);
        model.addAttribute("dormitory", dormitory);
        return "dormitoryDetail";
    }
    // ... 其他宿舍详情处理
}

5. 学生请假：

@Controller
public class LeaveController {
    @Autowired
    private LeaveService leaveService;
 
    @RequestMapping(value = "/leave", method = RequestMethod.POST)
    public String applyLeave(@RequestParam Long studentId, @RequestParam String reason,
                             @RequestParam Date startDate, @RequestParam Date endDate,
                             RedirectAttributes redirectAttributes) {
        boolean isSuccess = leaveService.applyLeave(studentId, reason, startDate, endDate);
        if (isSuccess) {
            return "redirect:/home";
        } else {
            redirectAttributes.addF
