我正在研究 Vaadin spring-security SAML 身份验证系统。问题是 - 当用户转到 vaadin 应用程序地址（如果它没有经过身份验证）时，它必须被重定向到 IDP 登录页面。但是代替此重定向（地址栏中的地址更改）我收到一个错误：无法加载小部件集：
/my_vaadin_app/VAADIN/widgetsets/com.vaadin.terminal.gwt.DefaultWidgetSet/com.vaadin.terminal.gwt.DefaultWidgetSet.nocache.js?1359109584453

有没有人建议为什么会发生这种情况。我读到 vaadin 只做某种内部重定向并且不理解外部重定向。
