Hello Sergey,
thanks again!
I figured out I could simply use the UriBuilder for this:
UriBuilder uriBuilder = UriBuilder.fromResource(MyJaxRsInterface.class);
URI uri = uriBuilder.path(MyJaxRsInterface.class, "retrieve").build("foo-id");
LOG.warn("PATH: " + jaxrsServerFactoryBean.getAddress() + '/' + uri.toString());
When distributing services in a cluster for example, we expect the jaxrs:server
address to be equal on all machines.
So this should do the trick too. Especially, when MyJaxRsInterface-service is
not available on the server, which
requires to know the endpoints to put them into the delivered resources for
example. :)
Best regards,
Marko
