XWiki Servlet 异常

Question

我想使用 XWiki 来记录一些过程，所以我下载了 xwiki-enterprise-installer-generic-5.0.1-standard.jar 并成功安装了它。当我运行 ./start_xwiki.sh 文件时，我可以在浏览器中打开 xwiki。

我面临的问题是，当我尝试在编辑页面中上传任何图像时，我收到这条消息“加载数据时出错”，当我检查日志时它说 javax.servlet.ServletException: 初始化 XWiki 上下文失败。

谁能帮我解决这个异常。提前致谢

这是堆栈跟踪

javax.servlet.ServletException: Failed to initialize the XWiki context.

Answer 1

如果您用于访问 wiki 的 URL 以 leo 开头，您可能会受到 this issue 的影响，这将在即将发布的 5.0.2 版本中修复。

同时，您可以通过定义 wiki 的 URL 来解决此问题：

• 打开/xwiki/bin/edit/XWiki/XWikiServerXwiki?editor=object
• 添加XWiki.XWikiServerClass类型的对象
• 将主机名 (leo) 放入 server 字段中
• 保存

它应该在那之后工作。
