Hi, I'm a Spring beginner. Currently studying this example.
So far, it works. For every mail that arrives in my Gmail inbox, eventually the code will print new line, like this:

23:51:21.736 INFO  [pool-2-thread-1][org.springframework.integration.samples.mail.imapidle.GmailInboundImapIdleAdapterTestApp] Message: GenericMessage [payload=org.springframework.integration.mail.AbstractMailReceiver$IntegrationMimeMessage@3b1d7ac6, headers={id=5a5ac31d-203c-c324-dcda-7ed8ae9214ff, timestamp=1570639881729}]

No idea how to do this with Spring...
