At runtime you can always use java code to configure and add / remove / modify routes in Camel etc.
There is api on CamelContext to work with that. And routes can be defined in java classes that extend RouteBuilder. As it is just java code you can do whatever you want to configure. Though there is runtime containers such as karaf/smx/fuse that can redeploy applications based on configuration changes etc. So you can externalize the configuration settings using property placeholders and configure these external configurations in .cfg or .properties files, and/or adjust them as well using JMX or OSGi Config Admin. Or if you follow the container / docker world, then you can build new images and upgrade by running the new images instead of the old.
