        if ("admin".equals(username) && "666666".equals(password)) {
            request.getSession().setAttribute("username", "admin");
            return "redirect:/view/index"; //客户端跳转
        } else {
            request.setAttribute("errorMsg", "用户名或密码有误");
            return "login";//服务器跳转
        }
