如何使用Camel组件File2中的include参数通过扩展来过滤文件

Question

我需要扩展名最简单的过滤器:fe文件20120523.173227.CustomerMaster05092012.QWERTY.xml route:

<from uri="file://{{fdr.folder.working.url}}&amp;include=*.xml"/>

不起作用:

在索引0附近悬挂元字符'*'

WARN - file://root_folder/working/) [FileConsumer] Consumer Consumer[file://root_folder/working/?delay=1000&delete=true&idempotent=false&include=*.xml&initialDelay=1000&readLock=changed] failed polling endpoint: Endpoint[file://root_folder/working/?delay=1000&delete=true&idempotent=false&include=*.xml&initialDelay=1000&readLock=changed].

好吧也许我的坏.我把整个文件包括在内:

<from uri="file://{{fdr.folder.working.url}}&amp;include=20120523.173227.CustomerMaster05092012.QWERTY.xml"/>

整个文件都可以.让我们尝试将*放在文件名的中间

<from uri="file://{{fdr.folder.working.url}}&amp;include=20120523.*.xml"/>

再次没关系.我们只在文件名中放一个数字

<from uri="file://{{fdr.folder.working.url}}&amp;include=2*.xml"/>

noup,骆驼没有找到这样的文件,我试过逃过星号,但它没有帮助.

<from uri="file://{{fdr.folder.working.url}}&amp;include=\*.xml"/>
and
<from uri="file://{{fdr.folder.working.url}}&amp;include=\\*.xml"/>

文件被忽略了.问题1:如何使用星号？

问题2:如何使用多种文件扩展名,例如include = .xml; .压缩

Answer 1

该死的,善意的想法来了,使用蛮力我发现正确的值包括:

.*.xml|.*.zip

Answer 2

您必须正确转义字符串中的反斜杠并使用字符串结尾符号“$”：include=.*\\.xml$

Answer 3

(?i).*.xml|.*.zip

如果您想要不区分大小写的文件扩展名匹配.
