@Target(value={}) @Retention(value=RUNTIME) public @interface Poller
PollerMetadata
options for the Messaging annotations for
polled endpoints.
It is an analogue of the XML <poller/>
element, but provides only simple attributes.
If the PollerMetadata
requires more options
(e.g. Transactional and other Advices) or initialDelay, receiveTimeout
etc,
the PollerMetadata
should be configured as
a generic bean and its bean name can be specified as the value
attribute of this annotation.
In that case, the other attributes are not allowed.
Non-reference attributes support Property Placeholder resolutions.
