Odd Even Sample =============== This example demonstrates the following aspects of the CORE EIP support available with Spring Integration: 1. Inbound Channel Adapter 2. Filter 3. Router (SpEL based) 4. Poller with Cron and Interval Trigers Messages are simply being emitted by the Poller (interval based or cron) triggering '**next()**' method of Counter class and sent to a '**numbers**' channel - Inbound Channel Adapter. From the '**numbers**' channel Messages are sent to an expression-based router (Spring Expression Language). All that the router does is simply routing messages to *OddLogger* and *EvenLogger* service To execute the Interval-based sample simply run **IntervalOddEvenDemoTest** class and for Cron-based sample simply run CronOddEvenDemo class, You should see the output similar to this: INFO : org.springframework.integration.samples.oddeven.OddLogger - odd: 1 at 2010-09-16 05:55:46 INFO : org.springframework.integration.samples.oddeven.EvenLogger - even: 2 at 2010-09-16 05:55:49 INFO : org.springframework.integration.samples.oddeven.OddLogger - odd: 3 at 2010-09-16 05:55:52 INFO : org.springframework.integration.samples.oddeven.EvenLogger - even: 4 at 2010-09-16 05:55:55
