How do I maintain values between spring task scheduled

Question

I want to maintain values between the spring task:scheduled, example my cron is to trigger every one hour.

<task:scheduled-tasks>
<task:scheduled ref="runScheduler" method="run" cron="0 0 * * * *" />
</task:scheduled-tasks>

I want to know, How do I get the value from last hour cron thread on next cron thread.

Answer 1

Cron attribute is used with @Scheduled annotation. Value of this attribute must be a cron expression.This cron expression will be defined in a properties file and key of related property will be used in @Scheduled annotation.

<task:scheduled-tasks>
<task:scheduled ref="runScheduler" method="run" cron="#{applicationProps['cron.expression']}" />
</task:scheduled-tasks>

Then use @Scheduled(cron = "${cron.expression}") annotation.
