CSS 和 JS 在应用 servlet 过滤器后不工作

Question

这是我第一次使用 dofilter 函数来验证我的 jsp Web 应用程序，一旦添加它并且 CSS 和 JS 在任何页面上都不起作用，我一遍又一遍地搜索但不能在我的代码中应用解决方案在下面找到 dofilter 方法。

@Override
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)
        throws IOException, ServletException {
    HttpServletRequest request = (HttpServletRequest) req;
    HttpServletResponse response = (HttpServletResponse) resp;

    String servletPath = request.getServletPath();

    // User information stored in the Session.
    // (After successful login).
    UserAccount loginedUser = AppUtils.getLoginedUser(request.getSession());

    if (servletPath.equals("/login")) {
        chain.doFilter(request, response);
        return;
    }

    HttpServletRequest wrapRequest = request;

    if (loginedUser != null) {
        // User Name
        String userName = loginedUser.getUserName();

        // Roles
        List<String> roles = loginedUser.getRoles();

        // Wrap old request by a new Request with userName and Roles information.
        wrapRequest = new UserRoleRequestWrapper(userName, roles, request);
    }

    // Pages must be signed in.
    if (SecurityUtils.isSecurityPage(request)) {

        // If the user is not logged in,
        // Redirect to the login page.
        if (loginedUser == null) {

            String requestUri = request.getRequestURI();

            // Store the current page to redirect to after successful login.
            int redirectId = AppUtils.storeRedirectAfterLoginUrl(request.getSession(), requestUri);

            response.sendRedirect(wrapRequest.getContextPath() + "/login?redirectId=" + redirectId);
            return;
        }

        // Check if the user has a valid role?
        boolean hasPermission = SecurityUtils.hasPermission(wrapRequest);
        if (!hasPermission) {

            RequestDispatcher dispatcher //
                    = request.getServletContext().getRequestDispatcher("/accessDeniedView.jsp");

            dispatcher.forward(request, response);
            return;
        }
    }

    chain.doFilter(wrapRequest, response);
}

还在页面

中找到CSSlink

<link href="vendor/fontawesome-free/css/all.min.css" rel="stylesheet"
type="text/css">

<link
href="https://fonts.googleapis.com/css?family=Nunito:200,200i,300,300i,400,400i,600,600i,700,700i,800,800i,900,900i"
rel="stylesheet">

我终于在淹没项目时发现了问题，它与从登录服务器中删除“/”并成为@WebServlet({ "/login" })
