@Scheduled doesn't take 7 fields anymore. What are the alternatives if I need the year field for the cron expression? I looked and saw Quartz cron trigger takes in 7 fields, but not sure if it'll work with spring integration inbound adapters?
You are right: there is no year field support in the org.springframework.scheduling.support.CronTrigger. And there is no Quartz support in Spring Integation's poller. However you still can configure a Quartz to call your method for inbound channel adapter and produce a message to the channel.
