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"
">  
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
