Question

我正在使用Spring Security，我想在自动重定向到登录页面时添加flash属性。但是，handle的{{1}}方法只有LogoutSuccessHandler，HttpServletRequest，HttpServletResponse作为参数。如何在Authentication方法中检索RedirectAttributes以添加Flash属性？或者是否有另一种方法可以将flash属性添加到注销重定向？非常感谢你。

对我来说，以下代码有效：

public class CustomLogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler {
    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
            throws IOException, ServletException {
        final FlashMap flashMap = new FlashMap();
        flashMap.put("information", "You've been logged out.");
        final FlashMapManager flashMapManager = new SessionFlashMapManager();
        flashMapManager.saveOutputFlashMap(flashMap, request, response);
        response.sendRedirect("/"); // or any other location you want
        super.handle(request, response, authentication);
    }
}
