I need to make a small Spring Integration application that synchronize a table from a JDBC source to another one, and I just need to launch that script just once in a while.
I'd like to make one poll from the inbound channel adapter (wait that the message flow through the chain) and exit the application.
I couldn't find any obvious way to do that: any suggestions?
@Steve suggests correct solution.
You should make your <poller> with some long fixed-delay do not start a new polling task. Or just stop an <inbound-channel-adapter> just after the polling task is run. For this purpose there is just enough make the channel as <publish-subscribe-channel> and add one more subscriber like:
<outbound-channel-adapter channel="processChannel" expression="@adapter.stop()">
So, this is the first part: How to make only the single poll?
Re. System.exit().
You should add in the end of your flow similar outbound-channel-adapter:
<outbound-channel-adapter channel="endProcessChannel" expression="T(System).exit()">
