Ref Component

The ref: component is used for lookup of existing endpoints bound in the Registry.

URI format

Where someName is the name of an endpoint in the Registry (usually, but not always, the Spring registry). If you are using the Spring registry, someName would be the bean ID of an endpoint in the Spring registry.

Runtime lookup

This component can be used when you need dynamic discovery of endpoints in the Registry where you can compute the URI at runtime. Then you can look up the endpoint using the following code:

And you could have a list of endpoints defined in the Registry such as:


In the sample below we use the ref: in the URI to reference the endpoint with the spring ID, endpoint2:

You could, of course, have used the ref attribute instead:

Which is the more common way to write it.
