The short answer to your question is that you need to
write a redirect resolver (a class that implements
RedirectResolver interface) before the you can use the
return ( new Redirect( ... ) ) class.
A redirect resolver is similar to a controller
resolver but it works in reverse.
The reason you are are seeing your redirect go to
Tomcat is because there is a stub implementation of
the RedirectResolver interface that assumes
localhost:8080 is your host, this stub is only meant
as an example and is not useful for your application
as provided.
Let me know if this does not answer your question.
