使用文件连接器Mule

mule应用程序中可使用的文件连接器数量是否有限制。 我有2个mule配置，如下所示

<spring:beans>
    <spring:import resource="classpath:ABC.xml" />
    <spring:import resource="classpath:XYZ.xml" />
</spring:beans>

在ABC.xml中，我有如下定义的文件连接器

<file:connector name="FileConnectorABC_1" autoDelete="false" streaming="false" workDirectory="${INBOUND_FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorABC_2" outputPattern="#[header:originalFilename]" />
<file:connector name="FileConnectorABC_3" autoDelete="false" streaming="false" workDirectory="${FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorABC_4" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorABC_5" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorABC_6" outputPattern="#[message.inboundProperties.originalFilename]" />

<file:connector name="FileConnectorXYZ_1" autoDelete="false" streaming="false" workDirectory="${INBOUND_FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorXYZ_2" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorXYZ_3" outputPattern="#[message.inboundProperties.originalFilename]"/>
<file:connector name="FileConnectorXYZ_4" />

在XYZ.xml中，我有如下定义的文件连接器

<file:connector name="FileConnectorABC_1" autoDelete="false" streaming="false" workDirectory="${INBOUND_FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorABC_2" outputPattern="#[header:originalFilename]" />
<file:connector name="FileConnectorABC_3" autoDelete="false" streaming="false" workDirectory="${FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorABC_4" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorABC_5" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorABC_6" outputPattern="#[message.inboundProperties.originalFilename]" />

<file:connector name="FileConnectorXYZ_1" autoDelete="false" streaming="false" workDirectory="${INBOUND_FAILURE_DIR}" workFileNamePattern="#[header:originalFilename]-#[function:dateStamp]-Processing" />
<file:connector name="FileConnectorXYZ_2" outputPattern="#[message.inboundProperties.originalFilename]" />
<file:connector name="FileConnectorXYZ_3" outputPattern="#[message.inboundProperties.originalFilename]"/>
<file:connector name="FileConnectorXYZ_4" />

XYZ.xml中的连接器似乎不起作用。在骡子日志中我看到

[[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-初始化：“connector.VM.mule.default.dispatcher.1700044407”。 [[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-开始：“connector.VM.mule.default.dispatcher.1700044407”。Obj [[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-初始化：“connector.VM.mule.default.dispatcher.1885360656”。 [[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-开始：“connector.VM.mule.default.dispatcher.1885360656”。Obj [[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-初始化：“connector.VM.mule.default.dispatcher.1448628158”。 [[my-app-1.0.0-SNAPSHOT].FlowA.stage1.02]INFO org.mule.lifecycle.AbstractLifecycleManager-开始：“connector.VM.mule.default.dispatcher.1448628158”。Obj

但文件不会被发送到目标位置

在上一篇文章中使用的mule配置下发送

为什么有这么多连接器？有些配置完全相同…David昨天查看配置时注意到了相同的事情，我减少了文件连接器的数量。一个用于入站，另一个用于出站。问题仍然存在，我注意到对于PathA和PathB，vm入站端点的初始化和启动与上面的日志相同。文件未放置在最终文件出站端点中。当我接触mule配置文件时，文件将放置在最终文件端点中。当mule再次启动时，似乎发生了一些阻塞。文件将按需要放置。你能给我一些我应该看的地方吗？atI已经添加了mule配置编辑我之前的文章。我怀疑是请求-应答路由器导致了问题，但事实并非如此。重新启动mule时，文件将在端点处传递。它似乎是排队的，而不是最初在端点处传递。请注意，PathA、PathB、PathC和PathD是文件的下拉列表。子流中的附加功能是文件转换和一些附加验证。感谢您提供所有这些附加信息，这将有助于理解您的问题。
