我需要最简单的扩展过滤器：fe 文件 20120523.173227.CustomerMaster05092012.QWERTY.xml 路由：
<from uri="file://{{fdr.folder.working.url}}&include=*.xml"/>
不起作用：
在索引 0 附近悬空元字符“*”

好吧，也许我的坏。我把整个文件包括在内：
<from uri="file://{{fdr.folder.working.url}}&include=20120523.173227.CustomerMaster05092012.QWERTY.xml"/>
整个文件没问题。让我们尝试将 * 放在文件名的中间
<from uri="file://{{fdr.folder.working.url}}&include=20120523.*.xml"/>
又没关系。让我们在文件名中只输入一位数字
<from uri="file://{{fdr.folder.working.url}}&include=2*.xml"/>
noup，camel 没有找到我尝试转义星号的此类文件，但它没有帮助。
<from uri="file://{{fdr.folder.working.url}}&include=\*.xml"/>
and
<from uri="file://{{fdr.folder.working.url}}&include=\\*.xml"/>
文件只是被忽略了。所以问题1：如何使用星号？
和问题 2：如何使用多个文件扩展名，例如 include= .xml；。压缩
谢谢
