问题主要出在 整合 ckfinder时候，ckfinder是相对独立，项目只需要引入 ckfinder.js 其他的都不需要。
<script type="text/javascript">
$(window).load(
function(){
var editor = CKEDITOR.replace('editor'); //editor就是要替换的元素
CKFinder.setupCKEditor( editor,"/assets/ckfinder/");
//'http://localhost/assets/ckfinder/'就是解压到assets虚拟目录下的ckfinder文件的URL，
//需要在同一域名下，虚拟主机中需要配置此路径
}
);
</script>
接下来要做的就是，在apache代理转交给play的URL剔除ckfinder的部分，不要转交，而自己解析。
