Full Content CronScheduledRoutePolicy Available as of Camel version 2.6 CronScheduledRoutePolicy is a ScheduledRoutePolicy that facilitates route activation, de-activation, suspension and resumption of routes based on a Quartz CronTrigger. Maven users will need to add a camel-quartz dependency to their pom.xml to avail this capability. <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-quartz</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> Relationship to the Quartz component All Scheduled route policies share the scheduler created by the Quartz component. In this way, scheduler, jobs and triggers can be managed in a common and consistent way. Relationship to the Quartz2 component From Camel 2.12.2 onwards you can also make use of the Quartz2 based implementation of this route policy. How it works In order to use a CronScheduledRoutePolicy it is necessary to instantiate an object of the type org.apache.camel.routepolicy.quartz.CronScheduledRoutePolicy. In order to perform a route operation at a given time the following information must be provided. Starting a route Parameter Name Type Default Value Description routeStartTime String   the initial scheduled Date and time as a Cron _expression_ for route start Stopping a route Parameter Name Type Default Value Description routeStopTime String   the initial scheduled Date and time as a Cron _expression_ for route stop routeStopGracePeriod int 10 seconds the time period to wait before initiating graceful route stop routeStopTimeUnit long TimeUnit.MILLISECONDS the time unit for the grace period expressed as java.util.concurrent.TimeUnit Suspending a route Parameter Name Type Default Value Description routeSuspendTime String   the initial scheduled Date and time as a Cron _expression_ for route suspension Resuming a route Parameter Name Type Default Value Description routeResumeTime String   the initial scheduled Date and time as a Cron _expression_ for route resumption Once the org.apache.camel.routepolicy.quartz.CronScheduledRoutePolicy is created it can be wired into the camel route as follows Configuring the policy In Java CronScheduledRoutePolicy startPolicy = new CronScheduledRoutePolicy(); startPolicy.setRouteStartTime("*/3 * * * * ?"); from("direct:start") .routeId("testRoute").routePolicy(startPolicy).noAutoStartup() .to("mock:success");; Using Spring <bean id="startPolicy" class="org.apache.camel.routepolicy.quartz.CronScheduledRoutePolicy"> <property name="routeStartTime" value="*/3 * * * * ?"/> </bean> <camelContext xmlns="http://camel.apache.org/schema/spring"> <route id="testRoute" routePolicyRef="startPolicy" autoStartup="false"> <from uri="direct:start"/> <to uri="mock:success"/> </route> </camelContext> See Also ScheduledRoutePolicy - for information on policy based scheduling capability for camel routes RoutePolicy - for information on route policies in general Quartz -for more information on the quartz component Stop watching space | Change email notification preferences View Online | View Changes
