一文件读取后停止文件入站通道适配器

问题描述

我们的应用程序使用 Spring 集成 file:inbound-channel-adapter 轮询目录以在文件被放置在那里时进行侦听.Spring Integration 然后启动一个 Spring Batch 作业，将要处理的文件的路径和名称交给作业.

显然，即使文件已被 Spring Batch 作业处理，文件轮询器仍会继续运行.因此，Spring 上下文保持打开状态，应用程序不会终止.有没有办法以编程方式或通过配置(优选)在读取一个文件后停止轮询器?

谢谢

解决方案

您可以在轮询器上使用 FireOnceTrigger，或者在 这个答案.

要以编程方式停止适配器，close() 上下文，或调用 adapter.stop()(@Autowire 适配器作为SourcePollingChannelAdapter.或者使用 <control-bus/> 并发送带有有效载荷 "adapterId.stop()" 的消息.>

Our application uses a Spring Integration file:inbound-channel-adapter to poll a directory to listen to when a file is dropped there. Spring Integration then starts a Spring Batch job, handing over to the job the path and name of the file to process.

Obviously, the file poller continues to run even after a file has been processed by the Spring Batch job. So, the Spring context remains open and the application does not terminate. Is there a way, programatically or through configuration (preferable), to stop the poller after one file has been read?

Thanks

解决方案

You can use a FireOnceTrigger on the poller, or one of the techniques described in addition to that, in this answer.

To programmatically stop the adapter, close() the context, or call adapter.stop() (@Autowire the adapter as a SourcePollingChannelAdapter. Or use a <control-bus/> and send a message with payload "adapterId.stop()".
