Quartz Component

The quartz: component provides a scheduled delivery of messages using the Quartz Scheduler 1.x .
Each endpoint represents a different timer (in Quartz terms, a Trigger and JobDetail).

Icon

If you are using Quartz 2.x then from Camel 2.12 onwards there is a Quartz2 component you should use

Maven users will need to add the following dependency to their pom.xml for this component:

URI format

The component uses either a CronTrigger or a SimpleTrigger. If no cron expression is provided, the component uses a simple trigger. If no groupName is provided, the quartz component uses the Camel group name.

You can append query options to the URI in the following format, ?option=value&option=value&...

Options

Parameter

Default

Description

cron

None

Specifies a cron expression (not compatible with the trigger.* or job.* options).

trigger.repeatCount

0

SimpleTrigger: How many times should the timer repeat?

trigger.repeatInterval

0

SimpleTrigger: The amount of time in milliseconds between repeated triggers.

job.name

null

Sets the job name.

job.XXX

null

Sets the job option with the XXX setter name.

trigger.XXX

null

Sets the trigger option with the XXX setter name.

stateful

false

Uses a Quartz StatefulJob instead of the default job.

fireNow

false

New to Camel 2.2.0, if it is true will fire the trigger when the route is start when using SimpleTrigger.

deleteJob

true

Camel 2.12: If set to true, then the trigger automatically delete when route stop. Else if set to false, it will remain in scheduler. When set to false, it will also mean user may reuse pre-configured trigger with camel Uri. Just ensure the names match. Notice you cannot have both deleteJob and pauseJob set to true.

pauseJob

false

Camel 2.12: If set to true, then the trigger automatically pauses when route stop. Else if set to false, it will remain in scheduler. When set to false, it will also mean user may reuse pre-configured trigger with camel Uri. Just ensure the names match. Notice you cannot have both deleteJob and pauseJob set to true.

usingFixedCamelContextNamefalseCamel 2.15.0: If it is true, JobDataMap uses the CamelContext name directly to reference the camel context, if it is false, JobDataMap uses use the CamelContext management name which could be changed during the deploy time.

For example, the following routing rule will fire two timer events to the mock:results endpoint:

When using a StatefulJob, the JobDataMap is re-persisted after every execution of the job, thus preserving state for the next execution.

Running in OSGi and having multiple bundles with quartz routes

Icon

If you run in OSGi such as Apache ServiceMix, or Apache Karaf, and have multiple bundles with Camel routes that start from Quartz endpoints, then make sure if you assign
an id to the <camelContext> that this id is unique, as this is required by the QuartzScheduler in the OSGi container. If you do not set any id on <camelContext> then
a unique id is auto assigned, and there is no problem.

Configuring quartz.properties file

By default Quartz will look for a quartz.properties file in the org/quartz directory of the classpath. If you are using WAR deployments this means just drop the quartz.properties in WEB-INF/classes/org/quartz.

However the Camel Quartz component also allows you to configure properties:

Parameter

Default

Type

Description

properties

null

Properties

Camel 2.4: You can configure a java.util.Properties instance.

propertiesFile

null

String

Camel 2.4: File name of the properties to load from the classpath

To do this you can configure this in Spring XML as follows

Enabling Quartz scheduler in JMX

You need to configure the quartz scheduler properties to enable JMX.
That is typically setting the option "org.quartz.scheduler.jmx.export" to a true value in the configuration file.

From Camel 2.13 onwards Camel will automatic set this option to true, unless explicit disabled.

Starting the Quartz scheduler

Available as of Camel 2.4

The Quartz component offers an option to let the Quartz scheduler be started delayed, or not auto started at all.

Parameter

Default

Type

Description

startDelayedSeconds

0

int

Camel 2.4: Seconds to wait before starting the quartz scheduler.

autoStartScheduler

true

boolean

Camel 2.4: Whether or not the scheduler should be auto started.

To do this you can configure this in Spring XML as follows

Clustering

Available as of Camel 2.4

If you use Quartz in clustered mode, e.g. the JobStore is clustered. Then from Camel 2.4 onwards the Quartz component will not pause/remove triggers when a node is being stopped/shutdown. This allows the trigger to keep running on the other nodes in the cluster.

Note: When running in clustered node no checking is done to ensure unique job name/group for endpoints.

Message Headers

Camel adds the getters from the Quartz Execution Context as header values. The following headers are added:
calendar, fireTime, jobDetail, jobInstance, jobRuntTime, mergedJobDataMap, nextFireTime, previousFireTime, refireCount, result, scheduledFireTime, scheduler, trigger, triggerName, triggerGroup.

The fireTime header contains the java.util.Date of when the exchange was fired.

Using Cron Triggers

Quartz supports Cron-like expressions for specifying timers in a handy format. You can use these expressions in the cron URI parameter; though to preserve valid URI encoding we allow + to be used instead of spaces. Quartz provides a little tutorial on how to use cron expressions.

For example, the following will fire a message every five minutes starting at 12pm (noon) to 6pm on weekdays:

which is equivalent to using the cron expression

The following table shows the URI character encodings we use to preserve valid URI syntax:

URI Character

Cron character

+

Space

Specifying time zone

Available as of Camel 2.8.1
The Quartz Scheduler allows you to configure time zone per trigger. For example to use a timezone of your country, then you can do as follows:

The timeZone value is the values accepted by java.util.TimeZone.

In Camel 2.8.0 or older versions you would have to provide your custom String to java.util.TimeZone Type Converter to be able configure this from the endpoint uri.
From Camel 2.8.1 onwards we have included such a Type Converter in the camel-core.
