Hi, I'm a Java developer too. There's lots of different ways to do this, 
but the key idea is that an Angular Application is just a bunch of static 
web resource files. From the Java Application Server's point of view 
there's nothing really different Angular Html and JS files than there is 
from any other gif, png, or css file that you might have already been used 
to deploying. Since all of the HTML generation is taken out of the Java 
Application server it just presents REST Services to the Angular App.

You can try and merge Angular 2 code into you main Java application project 
but I find it's easier to keep them separate. Use a technology like 
Angular-CLI to build and develop the Angular App and have the Angular CLI 
web server proxy your requests back to the Java application server. When 
you're ready to deploy into a proper dev/test environment you can either 
keep the Angular stuff separate under it's own web server eg Ngnix/Apache 
or you can merge in the compiled Angular code into you WAR file.

[AngularJS] Re: Angular 2 authentication?

The Docs from the main Angular site have a reasonable description of how to 
do "front-end" part of Authentication. In the section on Routing & 
Navigation look down about halfway for where it starts talking about Route 
Guards. A "Guard" is something that controls access to a route. Basically 
the idea is that the Guard prevents all access to the "protected" routes 
until the user has authenticated. 

It only talks about the browser side of things. You'll need to know how to 
do the back-end or find out how based on your particular back-end stack 
(Java, Python, .net etc..)

I was able to follow this and get authentication working for my project. 
See the following link.
