无法访问 Internet 的服务器上的 Tiles DTD 解析失败
Tiles DTD parsing failure on server with no internet access
该应用程序在可以访问 Internet 的服务器上运行良好，但在生产中我使用防火墙阻止了所有站点并且只允许一些内部域。因此无法上网。
以下错误表明它无法连接 struts.apache.org 端口 80

此外，我在将 JDK 版本从 1.6 更新到 1.8 之前没有遇到此问题，但更新后我在部署时遇到此错误。
如果这无论如何是相关的，我想补充一点，weblogic 实例也已更新到 12.1.3。
这里的问题是在部署时服务器上没有可用的互联网连接（实际上站点 struts.apache.org 在防火墙中被阻止）。
因此在部署期间我遇到了这个错误。请尝试在与这些站点有有效互联网连接的服务器上执行此操作，或在构建中包含这些文件（显然更新引用以引用包含的文件）。
在将 Web 应用程序项目从 struts 1.1 升级到 struts 1.2.9 后，我遇到了同样的问题。发现dtd的命名空间在struts 1.2已经改变了。必须更新 tiles 的文档类型-def.xml
