Spring集成 - 如何处理LoggingHandler中的异常

标签： java spring spring-integration

我一直致力于Spring Integration File Support，我需要将文件从输入目录移动到输出目录。成功移动到输出目录后，应将其存档，然后从输入目录中删除。我使用以下配置来实现此目的。

如果我的配置更好，请纠正我。

Spring集成配置：

    <int:channel id="inboundFileChannel"/>
<int:channel id="outboundFileChannel"/>
<int:channel id="archiveFileChannel"/>

 <int-file:inbound-channel-adapter channel="inboundFileChannel"
                              directory="file://${file.input.dir}" filename-pattern="*.txt" auto-startup="true" auto-create-directory="false">
    <int:poller fixed-rate="${file.poller.interval}"/>
</int-file:inbound-channel-adapter>

<int:service-activator input-channel="inboundFileChannel" output-channel="outboundFileChannel" ref="fileHandler"/>

<int-file:outbound-gateway request-channel="outboundFileChannel" reply-channel ="archiveFileChannel" directory="file://${file.output.dir}"
                           mode="REPLACE" delete-source-files="false" auto-create-directory="false" />

<int:service-activator input-channel="archiveFileChannel" ref="archiveFileHandler" method="copyToArchiveDirectory"/>

<int:logging-channel-adapter channel="inboundFileChannel" level="DEBUG"/>

<bean id="fileHandler" class="FileHandler"/>
<bean id="archiveFileHandler" class="ArchiveFileHandler"/>

如果存档目录不可用，我在服务激活器中有代码它应该终止应用程序。因此，在运行应用程序时，在第一次移动文件后，我删除了归档目录。然后我将新文件放在输入目录中，然后轮询该文件并将其发送到通道，但是服务激活器处理程序没有被选中，也没有检查存档目录是否存在。

我从日志中发现消息是第一次发送到ServiceActivatorHandler并移动了文件，但是第二次将消息发送到LoggingHandler。

由于我删除了归档目录（在应用程序运行时），因此将消息发送到LoggingHandler。 任何人都可以建议如何处理该异常，我可以编写代码来终止该应用程序。

如果我遗漏了任何东西，请纠正我。

<int:channel id="inboundFileChannel"/>

<int:service-activator input-channel="inboundFileChannel" output-channel="outboundFileChannel" ref="fileHandler"/>

<int:logging-channel-adapter channel="inboundFileChannel" level="DEBUG"/>

如果有两个消费者订阅了同一个频道（默认情况下为DirectChannel），则消息将交替发送给两个消费者 - 循环播放。

如果您希望将文件发送给两个消费者，请将其更改为发布/订阅者频道。

<int:publish-subscribe-channel id="inboundFileChannel"/>
