飞碟无法解析 ubuntu tomcat6 上的图像或 CSS
我遇到了使用 Flying Saucer 的 Grails Pdf 插件的问题。一切都按预期工作，直到我部署到运行 Tomcat6 的 Ubuntu 服务器上。然后我的 gsp 中对 css 和图像的引用失败，尽管我仍然可以渲染 PDF。
我尝试了两种不同的方法来构建 PDF，
ITextRenderer renderer = new ITextRenderer()
renderer.setDocument(url)
renderer.setDocumentFromString(content, baseUri)
使用“grails prod run-war”运行战争可以正常运行，而没有安全性的虚拟应用程序可以在本地运行，但当我将其部署在服务器上时也会失败。 （尽管我尝试呈现的内容都不受保护），但图像的 URL 是正确的。 （我已经尝试过绝对和相对 URL）两者都不会在 PDF 中呈现，但如果您从浏览器请求这些资源，它们就在那里。对未托管在服务器上的图像的引用确实有效。
所有这些让我相信，当你执行 sudo apt-get install tomcat6 时，与 ubuntu 一起安装的 tomcat6 的配置很有趣。我知道它使用用户“tocat6”运行，而不是像许多安装那样使用“root”运行。这是否会导致 Flying Saucer 无法获得正确的访问权限来获取所引用的文件？
I am running into an issue with the Grails Pdf plugin which uses Flying Saucer. Everything works as expected until I deploy onto an Ubuntu server running Tomcat6. Then references in my gsp's to css and images fail, though I still get the PDF to render.
I have tried two different approaches to building the PDF
ITextRenderer renderer = new ITextRenderer()
renderer.setDocument(url)
renderer.setDocumentFromString(content, baseUri)
Running a war with 'grails prod run-war' works, running and a dummy app with no security works locally, but fails when I deploy it on the server as well. (though none of the content I am trying to render is secured anyway), the URL's of the images are correct. (I have tried both absolute and relative URL's) neither gets rendered in the PDF, but if you request those resources from a browser they are there. References to images not hosted on the server do work.
All this leads me to believe that the tomcat6 that gets installed with ubuntu when you do sudo apt-get install tomcat6 is configured funny somehow. I know that it runs with user 'tocat6' instead of 'root' as many installations do. Could that be causing Flying Saucer to somehow not have the right access to get at the files being referenced?

由于除了 images/css 之外的所有内容都正常，我猜你的 baseURI 不正确？！我在生产系统上有这段代码并且它正在运行。所有图像均引用绝对值：
您的 baseURI 设置为多少？
Since everything except the images/css is working, I guess your baseURI is not correct?! I have this code on a production system and it is working. All the images are referenced absolut:
What is your baseURI set to?
