solr-routes [Amherst College Digital Collections]

Fedora-Solr integration

Camel has a built-in endpoint for Solr, which makes integration really easy. Because the solr-routes are managed in a separate camelContext, they are connected to the fedora-routes over the vm component.

<camelContext id="solr-routes" xmlns="http://camel.apache.org/schema/spring">
