Apache camel 如何使用标头值动态写入Camel中的不同文件夹？

我需要将文件传输到多个目标系统。 这些目标系统在源系统的文件名中定义

例如：

SLPNPM_ID0001_T20190329000000.DAT -> target directory : /SLPNPM/
SLPNP1_ID0001_T20190329000001.DAT -> target directory : /SLPNP1/
SLPNP2_ID0002_T20190329000002.DAT -> target directory : /SLPNP2/
...                                   ...

所以，我实现了下面的代码

CamelContext.xml

    <route id="_route1">
      <from id="_from1" uri="direct:source"/>
      <bean id="_setTarget" ref="setTarget"/>
      <to id="_to1" uri="file:C:/{${header.targetNeId}}/outputFolder"/>
    </route>
    <bean id="setTarget" class="com.ktds.openmzn.sample.SetTarget"/>

错误日志

如果我想满足我的业务需求，我该如何处理它？

您是如何将文件导入到这条路径的？它们是否按顺序发送到此路由（例如，扫描源目录的拆分器正在将这些文件发送到此路由）？我找到了它。谢谢，你是怎么把文件送到那条路线的？它们是否按顺序发送到此路由（例如，扫描源目录的拆分器正在将这些文件发送到此路由）？我找到了它。非常感谢。
