= Task Events

This is a task application that emits batch job events to the following channels:

	* job-execution-events
	* step-execution-events
	* chunk-events
	* item-read-events
	* item-process-events
	* item-write-events
	* skip-events

Note: More information on this topic is available https://docs.spring.io/spring-cloud-task/current-SNAPSHOT/reference/htmlsingle/#stream-integration-batch-events[here].

== Requirements:

* Java 7 or Above

== Build:

[source,shell,indent=2]
----
$ ./mvnw clean install
----

== Execution:

[source,shell,indent=2]
----
$ java -jar target/batch-events-1.1.0.BUILD-SNAPSHOT.jar --spring.cloud.stream.bindings.batch-events.contentType=application/json
----

For example you can listen for specific job execution events on a specified channel with a Spring Cloud Stream Sink
like the log sink using the following:

[source,shell,indent=2]
----
$ java -jar <PATH_TO_LOG_SINK_JAR>/log-sink-rabbit-1.0.2.RELEASE.jar --server.port=9090
--spring.cloud.stream.bindings.input.destination=job-execution-events
----

== Dependencies:

The batch-events sample requires an instance of RabbitMQ to be running.
