Available as of Camel 2.8
The apns component is used for sending notifications to iOS devices. The apns components use javapns library.
The component supports sending notifications to Apple Push Notification Servers (APNS) and consuming feedback from the servers.
The consumer is configured with 3600 seconds for polling by default because it is a best practice to consume feedback stream from Apple Push Notification Servers only from time to time. For example: every 1 hour to avoid flooding the servers.
The feedback stream gives informations about inactive devices. You only need to get this informations every some hours if your mobile application is not a heavily used one.
Maven users will need to add the following dependency to their
pom.xml for this component:
To send notifications:
To consume feedback:
Empty by default. Configure this property in case you want to statically declare tokens related to devices you want to notify. Tokens are separated by comma.
Delay in seconds between each poll.
Seconds before polling starts.
Time Unit for polling.
true, use fixed delay between pools, otherwise fixed rate is used. See ScheduledExecutorService in JDK for details.
You can append query options to the URI in the following format,
ApnsComponent must be configured with a
com.notnoop.apns.ApnsService. The service can be created and configured using the
org.apache.camel.component.apns.factory.ApnsServiceFactory. See further below for an example. And as well in the test source code.
Exchange data format
When Camel will fetch feedback data corresponding to inactive devices, it will retrieve a List of InactiveDevice objects. Each InactiveDevice object of the retrieved list will be setted as the In body, and then processed by the consumer endpoint.
Camel Apns uses these headers.
Empty by default.
STRING, PAYLOAD, APNS_NOTIFICATION
In case you choose PAYLOAD for the message type, then the message will be considered as a APNS payload and sent as is. In case you choose STRING, message will be converted as a APNS payload. From Camel 2.16 onwards APNS_NOTIFICATION is used for sending message body as com.notnoop.apns.ApnsNotification types.
ApnsServiceFactory builder callback
ApnsServiceFactory comes with the empty callback method that could be used to configure (or even replace) the default
ApnsServiceBuilder instance. The signature of the method could look as follows:
And could be used like as follows:
Camel Xml route
Camel Java route
