configure SEDA URI/options with Spring PropertyPlaceholderConfigurer?

[Doug Douglass]

I'd like to move some SEDA endpoint options out of the Camel XML
configuration and into a Spring PropertyPlaceholderConfigurer, but I'm
struggling a bit.

Here's a snip of the current Camel XML with the URIs I'm trying to configure
marked with "-->":

<camelContext>
    <route>
      <from uri="timer://poller?period=300000" />
      <to uri="bean:customerChangeEventService?methodName=getEvents" />
      <splitter>
        <el>${in.body}</el>
        <idempotentConsumer messageIdRepositoryRef="eventIdRepository">
          <el>${in.body.eventId}</el>
-->      <to uri="seda:customerChangeEvent?size=6000" />
        </idempotentConsumer>
      </splitter>
      <onException>
        <exception>java.lang.Throwable</exception>
        <to uri="seda:eventProcessingErrors"/>
      </onException>
    </route>

    <route>
-->  <from uri="seda:customerChangeEvent?size=6000" />
      ...
    </route>

    ...
</camelContext>

In practice, the configuration may also include the concurrentConsumers
option.

Optimistically, I configured a PropertyPlaceholderConfigurer and tried
changing the URIs to
"seda:customerChangeEvent?size=${camel.customer.event.queue.size}", but the
property isn't replaced, and camel complains when it tries to
convert ${camel.customer.event.queue.size} into an integer.

Now I'm struggling trying to configure/instantiate a SedaComponent directly
via Spring beans XML.

Any pointers to examples?

Anyone care to provide a quick example?

If it helps, this project is using Camel 1.6.1.

TIA,
Doug
