Greetings, I am currently using java DSL and have been investigating Fuse
and Fabric8 as possible alternatives. Currently I have a route that does
something like the following:
final String cron =
this.config.automationCasesDBMonitorCron().replaceAll(" ", "+");
final String quartzURI =
"quartz://case_automation/processAutomationCasesFromDB?cron=" + cron;
fromStandard(quartzURI)
.routeId(ROUTE_ID_ETL_MONITOR_TIMER) // timer trigger
.transacted(TxnHelper.KEY_TXNPOLICY_REQUIRED) // make the route
transacted
.to(InOnly, endpointAMQ(this.config.queueETLCheckEvent())); // put
an event to be consumed
As you can see, I fetch the names of queues and cron trigger configs from a
configuration object. The actual config class goes to a database to get the
configuration but that is not relevant to the question. The question is how
can I implement something like this inside the spring DSL (which I am
admittedly unfamiliar with). Currently I am trying to cross code my routes
and for this one I have the following:
<camelContext xmlns="http://camel.apache.org/schema/spring";>
<route id="ETLMonitorTimer">
<from
uri="quartz://case_automation/processAutomationCasesFromDB?cron="/>
<transacted ref="REQUIRED"/>
<to uri="activemq:queue:"/>
</route>
</camelContext>
As you can see I don't have the cron trigger or the destination queue that
I get normally from the config file so I am at a bit of a loss as to how to
accomplish this. I was thinking with a property placeholder i could do
something like this:
<bean id="configBean" class="com.foo.ConfigMgr"/>
<camelContext xmlns="http://camel.apache.org/schema/spring";>
<propertyPlaceholder ref="configBean"/>
<route id="ETLMonitorTimer">
<from
uri="quartz://case_automation/processAutomationCasesFromDB?cron={{etl_monitor_cron}}"/>
<transacted ref="REQUIRED"/>
<to uri="activemq:queue:{{event_queue}}"/>
</route>
</camelContext>
But I may be way off base on how to do that. I confess I have always
thought the Spring XML DSL to be much less flexible and powerful than the
Java DSL but I am open to being proven wrong. :)
So any help here? Thanks a bunch.
