Struts 2 jquery插件需要互聯網連接

我正在使用struts2-jquery-plugin-3.1.0.jar進行UI的struts 2 web應用程序。應用程序部署在tomcat上，如果啓用了Internet連接，服務器就會正常啓動，但是如果服務器位於防火牆後面或者Internet連接已打開，啓動服務器時會引發以下異常。Struts 2 jquery插件需要互聯網連接

它看起來像罐需要互聯網連接才能啓動，請讓我知道如何啓動服務器，而無需連接互聯網。提前致謝。

這是在struts-plugin.xml文件中聲明的struts的DTD版本與您正在使用的Struts版本之間的不兼容。

是的，我改變的struts-plugin.xml的罐子裏文件從2.1.7到2.1（在應用程序的struts.xml文件中聲明）。 – Sunny

你可以嘗試把這個依賴項放到應用程序容器的庫文件夾中，並測試它是否有幫助嗎？

檢查，如果你在你的WEB-INF/lib文件夾中有支柱罐子的多個版本。只保留你需要的版本並嘗試。

這意味着它找不到聲明爲strut-plugin.xml的dtd
我解決了在strust2-jquery - *。jar中編輯struts-plugin.xml的問題。刪除dtd聲明後的尾隨空格。即改變這種

<!DOCTYPE struts PUBLIC 
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 
    "http://struts.apache.org/dtds/struts-2.3.dtd ">

到

<!DOCTYPE struts PUBLIC 
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 
    "http://struts.apache.org/dtds/struts-2.3.dtd">
