Ionic with Spring Security

I am new with Ionic and thought about using spring security for login, I have read that the token sent back causes confusion for these two to work. Can someone just explain why there is an issue in depth as in why It doesnt work well together?

Where did you hear that? what kind of token? this is far too vague.
I use spring security and a JWT token generated by JHipster with an Ionic app without any issue.

Is your project on git? OR can i see just the sample of where you use spring security?

Sorry no but there 's nothing special to Ionic it’s pure AngularJS as generated by JHipster, so you can generate your own with the authentication scheme you like.
