Java MVC会议室管理系统：管理员和员工角色的增删改查功能

以下是一个简单的会议室管理系统的JAVA+MVC代码示例，包含管理员和员工两个角色的增删改查功能：\n\n1. Employee类：\n\njava\npublic class Employee {\n private int emp_id; \n private String emp_name; \n private String emp_sex; \n private Date emp_birthday; \n private String emp_email; \n private int emp_dep_id; \n private String emp_username; \n private String emp_password; \n private int emp_role; \n\n // 省略构造函数、getter和setter方法\n}\n\n\n2. EmployeeDAO类：\n\njava\npublic class EmployeeDAO {\n public List<Employee> getAllEmployees() {\n // 查询所有员工的逻辑\n }\n \n public Employee getEmployeeById(int emp_id) {\n // 根据员工ID查询员工的逻辑\n }\n \n public void addEmployee(Employee employee) {\n // 添加员工的逻辑\n }\n \n public void updateEmployee(Employee employee) {\n // 更新员工信息的逻辑\n }\n \n public void deleteEmployee(int emp_id) {\n // 删除员工的逻辑\n }\n}\n\n\n3. Dep类：\n\njava\npublic class Dep {\n private int dep_id; \n private String dep_name; \n private String dep_head; \n private String dep_info; \n\n // 省略构造函数、getter和setter方法\n}\n\n\n4. DepDAO类：\n\njava\npublic class DepDAO {\n public List<Dep> getAllDepartments() {\n // 查询所有部门的逻辑\n }\n \n public Dep getDepartmentById(int dep_id) {\n // 根据部门ID查询部门的逻辑\n }\n \n public void addDepartment(Dep department) {\n // 添加部门的逻辑\n }\n \n public void updateDepartment(Dep department) {\n // 更新部门信息的逻辑\n }\n \n public void deleteDepartment(int dep_id) {\n // 删除部门的逻辑\n }\n}\n\n\n5. Meetroom类：\n\njava\npublic class Meetroom {\n private int mt_id; \n private String mt_name; \n private String mt_location; \n private int mt_capacity; \n private String mt_status; \n\n // 省略构造函数、getter和setter方法\n}\n\n\n6. MeetroomDAO类：\n\njava\npublic class MeetroomDAO {\n public List<Meetroom> getAllMeetrooms() {\n // 查询所有会议室的逻辑\n }\n \n public Meetroom getMeetroomById(int mt_id) {\n // 根据会议室ID查询会议室的逻辑\n }\n \n public void addMeetroom(Meetroom meetroom) {\n // 添加会议室的逻辑\n }\n \n public void updateMeetroom(Meetroom meetroom) {\n // 更新会议室信息的逻辑\n }\n \n public void deleteMeetroom(int mt_id) {\n // 删除会议室的逻辑\n }\n}\n\n\n7. Meeting类：\n\njava\npublic class Meeting {\n private int m_id; \n private String m_name; \n private int m_resroomid; \n private int m_resempid; \n private int m_number; \n private Date m_starttime; \n private Date m_endtime; \n private Date m_restime; \n private Date m_canceltime; \n private String m_info; \n private String m_status; \n\n // 省略构造函数、getter和setter方法\n}\n\n\n8. MeetingDAO类：\n\njava\npublic class MeetingDAO {\n public List<Meeting> getAllMeetings() {\n // 查询所有会议的逻辑\n }\n \n public Meeting getMeetingById(int m_id) {\n // 根据会议ID查询会议的逻辑\n }\n \n public void addMeeting(Meeting meeting) {\n // 添加会议的逻辑\n }\n \n public void updateMeeting(Meeting meeting) {\n // 更新会议信息的逻辑\n }\n \n public void deleteMeeting(int m_id) {\n // 删除会议的逻辑\n }\n}\n\n\n以上是一个简单的会议室管理系统的JAVA+MVC代码示例，你可以根据需要进行进一步的开发和完善。
