mysql - 道场需要互联网吗？ (struts2)

Question

我不知道为什么当我尝试运行一个确切的项目(struts2+hibernate+mysql)时它给我 404 错误，但是在其他项目中我没有这个问题..是因为 MySQL jar或者可能是因为 struts2-dojo-plugin-2.3.4.jar(如“原因”中所述)？我需要一个解决方案，因为我总是必须连接到互联网才能进行开发。非常感谢您。

来自 http://www.coderanch.com/t/536448/Struts/run-Struts-offline和 http://struts.1045723.n5.nabble.com/S2-attempts-to-access-www-opensymphony-com-on-Struts-startup-td3481060.html ...

尝试将 struts.xml 中的 DTD 引用从

更改为

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration//EN" 
    "http://struts.apache.org/dtds/struts-2.0.dtd"> 

到

<!DOCTYPE struts SYSTEM "struts-2.0.dtd">

并且不要忘记检查项目中对在线资源的任何其他引用。
