问题
My website calls a rest service which is also on the same application. I don't want to change the domain of the rest address if it's hosted on a different domain name and/or port. I want to get the domain, port and application path programmatically.
If we are accessing the website like
http://example.com/article1
then I should get http://example.com
or if our address is like below
http://example.com:8080/ArticleSite/article1
then I want to get http://example.com:8080/ArticleSite
How can this be done?
I did look at the answers at
What's the best way to get the current URL in Spring MVC?
but non are getting the application path.

Hope im not late for the party.
I had issue similar to yours, and i managed to solve first part of your question by using ServletUriComponentsBuilder.
I've been using it like this to get current server URL:
ServletUriComponentsBuilder.fromCurrentContextPath().build().toUriString();
which would return http://localhost:8080 for me
EDIT: everything i wrote will not work, i'm working on a similar issue as OP, and this fix partially worked for me, after some digging i found this question, that has already been answered:
Is possible to get web application full url from Spring service that is invoked by task?
EDIT2: this guy also says it's not possible: How do I find base URL during Spring MVC startup?
