Spring MVC：無法渲染視圖 - $ {}正在渲染

我是Spring MVC的新手。我最終沒有查看渲染應有的價值，但渲染$ {}

的web.xml

嘗試修復你的web.xml聲明（你是混合2.5和3.0版本）。以此爲例：http://javahowto.blogspot.fr/2010/07/sample-webxml-servlet-30-with-ejb-ref.html。另外，你在哪裏部署應用程序？ – 2014-08-30 15:15:55

嗨JB我改變了web.xml到下面，但沒有運氣，仍然得到相同的輸出:( – AKumar 2014-08-30 16:47:43

不知何故，EL評價正在得到您的設置禁用（我猜的servlet容器的版本不匹配和web.xml中聲明）。嘗試通過它設置爲false添加isELIgnored屬性和檢查

<%@ page isELIgnored="false" %>
