You might first want to read Writing Components for a background in how to implement a new component. Typically it means you write an implementation of the Component interface, usually deriving from DefaultComponent.
You can then register your component explicitly via:
CamelContext context = new DefaultCamelContext(); context.addComponent("foo", new FooComponent(context));
However you can use the auto-discovery feature of Camel where by Camel will automatically add a Component when an endpoint URI is used. To do this you would create a file called:
(You can add other property configurations in there too if you like.)
Then if you refer to an endpoint as
foo://somethingOrOther Camel will auto-discover your component and register it.
You can configure a component via Spring using the following mechanism:

If you want to add explicit Spring 2.x XML objects to your XML then you could use the
xbean-spring which tries to automate most of the XML binding work for you; or you could look in camel-spring at
CamelNamespaceHandler you’ll see how we handle the Spring XML stuff (warning it’s kinda hairy code to look at :smile:). If you wanted
<fooComponent> to be a standard part of the core Camel schema then you’d hack that file to add your component & contribute a patch to the camel XSD. Otherwise you could write your own namespace & schema if you prefer.
