How do I configure the default maximum cache size for ProducerCache or ProducerTemplate

Available as of Camel 2.3

You can configure the default maximum cache size by setting the Exchange.MAXIMUM_CACHE_POOL_SIZE property on CamelContext.

getCamelContext().getProperties().put(Exchange.MAXIMUM_CACHE_POOL_SIZE, "50");

And in Spring XML its done as:

<camelContext>
   <properties>
      <property key="CamelMaximumCachePoolSize" value="50"/>
   </properties>
...
</camelContext>

The default maximum cache size is 1000.

At runtime you can see the ProducerCache in JMX as they are listed in the services category.
