@Scheduled's int attributes do not allow for placeholder values [SPR-8067]

[spring-projects-issues]

Eliran Bivas opened SPR-8067 and commented

In XML declaration it was possible to read configuration parameter for fixed-delay, fixed-rate (and the future initial-wait):

<task:scheduled-tasks scheduler="cleanServiceScheduler">
   <task:scheduled ref="cleanService" method="clean" fixed-delay="${admin.clean.rate.milis}"/>
</task:scheduled-tasks>

When using the annotation driven configuration the parameters accept constant values.
Will be nice to have some attribute like fixedRateProperty that will read properties from configuration.

This patch allows expesssions like "${fixedDelay}" to be used with the @Scheduled annotation

This patch was submitted nearly a year ago. Is there any way we can get this (or something like it) in? Without this, it is very difficult to use @Scheduled as all the delays must be hardcoded. Thanks.

Finally resolved for 3.2.2, adding 'fixedDelayString', 'fixedRateString' and 'initialDelayString' attributes - keeping the existing attributes declared as int, for convenience as well as backwards compatibility.
