IM具有一些異常，同時運行的Spring應用程序我不知道爲什麼它的發生，請幫助我我已經在我的系統中導入的應用程序並嘗試運行，但它顯示了這個錯誤，請幫我指點迷津出來NoClassDefFoundError的：使用javax/servlet的/ AsyncListener

如何與現有的配置 – henrycharles
確保你的servlet容器中刪除此支持3.0規範（[鏈接]（http://tomcat.apache.org/whichversion.html）爲Tomcat，Jetty的8和9）。 XSI：然後在web.xml中使用3.0版本的schemaLocation =「http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd 「，version =」3.0「。如果您使用maven，請查看依賴關係。 – madhead
