功能介绍：

登录、注册、用户/管理员(角色)、用户信息管理、科系信息管理、查看所有科系、新增科系信息、删除指定科系、修改科系信息、病房信息管理、病人信息管理、医生类型管理、病人手术管理

登录服务类：

public class LoginServlet extends HttpServlet {private static final long serialVersionUID = 1L;protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {request.setCharacterEncoding("utf-8");String username = request.getParameter("username");String password = request.getParameter("password");String level = null;//实例化UserDao对象UserDao userDao = new UserDao();User user = userDao.login(username, password);//判断是否登录成功if(user != null){//成功level = user.getLevel();//判断权限if(level.equals("用户")){//将用户对象放到session中request.getSession().setAttribute("user", user);//转发到user.jsp中request.getRequestDispatcher("user.jsp").forward(request, response);}else{//将管理员对象放到session中request.getSession().setAttribute("admin", user);//转发到admin.jsp中request.getRequestDispatcher("admin.jsp").forward(request, response);}	}else {//失败request.setAttribute("info"," 错误:用户名或密码错误！");request.getRequestDispatcher("message.jsp").forward(request, response);}}}

用户管理控制层：

public class UserExitServlet extends HttpServlet {private static final long serialVersionUID = 1L;protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {//获取SessionHttpSession session = request.getSession();session.invalidate();//转发到login.html页面response.sendRedirect("login.html");}protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {}}

管理员服务类：

public class AdminDao extends HttpServlet {private static final long serialVersionUID = 1L;private String action;//存储操作描述//接收请求protected void doGet(HttpServletRequest request, HttpServletResponse
