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);
}
}
}
