解决办法：



就是因为断网了，不能download DTD了所以就报错，解决方法是：
根据DTD中的这个http://struts.apache.org/dtds/struts-2.0.dtd链接将struts-2.0.dtd文件下载到本地硬盘上，然后将DTD中的http://struts.apache.org/dtds/struts-2.0.dtd链接替换成，struts-2.0.dtd文件在硬盘上的路径即可。


具体： 


将 
  struts.xml  
   中的 
           "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 
  
">   
   
   

     <!DOCTYPE struts PUBLIC 
   
 
   

              "Apache SoftWare Foundation//DTD Struts Configuration 2.0//EN" 
   
 
   

              "D:/Anther-hlep-lib-jar/struts-2.0.dtd">




注解：D:/Anther-hlep-lib-jar/struts-2.0.dtd   为struts-2.0.dtd 在我本地纸盘的路径
