integration feed - startup

[srinivas_vsk]

Hello,

This might have been asked before but didnt find any reference. I have a feed integration which needs to start polling after my application context finishes loading. Is there a way to start this polling after the application start up ? i know i could increase the poller time a bit but looking for other options

Thanks

Are you talking about feed as RSS/ATOM feed?

[srinivas_vsk]

yes feed:inbound-channel-adapter

This fires up before my application server is fully up. Probably this is the case for all inbound-channel-adapter's as well, but think it will be nice to delay the polling until the Application context is fully started/ loaded and your web application is up and running.

Yeah, its simple. Set auto-startup to 'false'

<int-feed:inbound-channel-adapter id="feedAdapter" 
			channel="feedChannel" 
			auto-startup="false" 
			url="http://rss.cnn.com/rss/cnn_topstories.rss">
	<int:poller fixed-rate="10000" max-messages-per-poll="100" />
</int-feed:inbound-channel-adapter>

And then the code you can do this:

SourcePollingChannelAdapter spca = ac.getBean("feedAdapter", SourcePollingChannelAdapter.class);
spca.start();

Have seen the auto-startup flag i can turn off i understand. The concern is somewhere i need to write the code to manually start this channel back maybe via custom context listener, so im wondering if springs application context can do it for me? instead after it finishes loading.

trying to avoid to manually invoke and achieve the same via another parameter or configuration?

Thanks

I guess I am not following. start method is executed right before AC is returned to you. It is the last step in the lifecycle, so I am not sure what you mean when you say it is started before AC is loaded. Can you elaborate?
