我想使用grails 2.3.0、grails 资源插件 1.2和videojs显示视频。可以访问图像，但不能访问视频。我写的相应代码是：
23 <video id="knowledgeVideos" class="video-js vjs-default-skin" controls preload="none" width="640" height="264"
24 poster="${resource(dir:'images', file:'oceans-clip.png')}"
25 data-setup="{}">
26 <source src="${resource(dir:'videos', file:'ocean-clip.mp4')}" type='video/mp4' />
27 <source src="${resource(dir:'videos', file:'ocean-clip.webm')}" type='video/webm' />
28 <source src="${resource(dir:'videos', file:'ocean-clip.ogg')}" type='video/ogg' />
29
30 <track kind="captions" src="demo.captions.vtt" srclang="en" label="English"></track><!-- Tracks need an ending tag thanks to IE9 -->
31 </video>
我的视频位于web-app/videos
prayag@prayag:~/zazzercode/knowledge2coin$ ls -l web-app/videos/
total 21156
-rw-rw-r-- 1 prayag prayag 7036928 Oct 6 11:07 oceans-clip.mp4
-rw-rw-r-- 1 prayag prayag 14625011 Oct 6 11:07 oceans-clip.webm
我还添加/videos/*了资源模式conf/Config.groovy
36 // What URL patterns should be processed by the resources plugin
37 grails.resources.adhoc.patterns = ['/images/*', '/videos/*','/css/*', '/js/*', '/plugins/*']
我得到的例外是
