请试试这个
从（“file：//E：/input/？delete=true”）.to（“file：//E：/outputdir”）

我有这个蓝图 Camel 路线下面

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
           xsi:schemaLocation="

             http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd
             http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0 http://aries.apache.org/schemas/blueprint-cm/blueprint-cm-1.1.0.xsd">

  <camelContext id="blueprint-bean-context" xmlns="http://camel.apache.org/schema/blueprint">
    <route id="WatchDirectoryRoute">
      <from uri="file://home/wagner/___inputdir/?delete=true"/>
      <to uri="file:///home/wagner/___outputdir?fileName=copy-of-${file:name}"/>
    </route>
  </camelContext>

</blueprint>

karaf.log显示路由正在监视目录

2023-06-28T18:41:58,253 | DEBUG | Camel (blueprint-bean-context) thread #39 - file://home/wagner/___inputdir/ | GenericFileConsumer              | 107 - org.apache.camel.camel-file - 3.20.6 | Took 0ms to poll: home/wagner/___inputdir
2023-06-28T18:41:58,754 | DEBUG | Camel (blueprint-bean-context) thread #39 - file://home/wagner/___inputdir/ | GenericFileConsumer              | 107 - org.apache.camel.camel-file - 3.20.6 | Took 0ms to poll: home/wagner/___inputdir

但是将文件放在/home/wagner/_inputdir中不会触发路由。
我的蓝图xml可能有什么问题？
为了补充信息，下面的蓝图工作正常

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="timer:test" />
            <to uri="log:test" />
        </route>
    </camelContext>

</blueprint>
