GH-8625: Add Duration support for <poller> (#8627)
* GH-8625: Add Duration support for `<poller>` Fixes #8625 The duration can be represented in a ISO 8601 format, e.g. `PT10S`, `P1D` etc. The `<poller>` and `@Poller` don't support such a format. * Introduce a `PeriodicTriggerFactoryBean` to accept string values for trigger options and parse them manually before creating the target `PeriodicTrigger` * Use this `PeriodicTriggerFactoryBean` in the `PollerParser` and `AbstractMethodAnnotationPostProcessor` where we parse options for the `PeriodicTrigger` * Modify tests to ensure that feature works * Document the duration option * Add more cross-links into polling docs * Fix typos in the affected doc files * Add `-parameters` for compiler options since SF 6.1 does not support `-debug` anymore for method parameter names discovery * Fix typos Co-authored-by: Gary Russell <[email protected]> --------- Co-authored-by: Gary Russell <[email protected]>
