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

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

Available as of Camel 2.3

This applies to ConsumerCache and ConsumerTemplate as well.

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.
