Question

我正在开发一个应用程序，遇到与hibernate ehcache相关的问题。

当没有网络时，我正在处理的应用程序无法启动。我已经检查了Tomcat日志，我在下面看到了例外情况。

为什么抛出以下异常？此外，如果网络没有问题，我不会遇到问题。

此致

您可以发布配置标头（例如ehcache.xml）吗？

我记得ehcache试图访问互联网时遇到问题（我不确定这是不是你的情况，但可能值得拍摄）。但我通过将updateCheck =“false”添加到我的ehcache.xml配置（它禁用自动更新）来解决它：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false">

P.S。

也许这个帖子White spaces are required between publicId and systemId可以给你一个关于解决方案的提示。

P.P.S。也许您的应用程序无法访问ehcache.xsd？ How to use local xsd for EhCache with Spring

Cannot find the declaration of element 'ehcache'

修改

您的应用程序看起来无法找到ehcache.xsd文件。所以，试试这个帖子中的解决方案：Cannot find the declaration of element 'ehcache'

该例外对我没有意义，但我遇到了从Web引用的DTD / XSD问题。如果没有Internet访问，则无法检索DTD / XSD，从而导致各种错误。

如果没有网络，Hibernate应用程序无法启动
