I'm about to implement a token based authentication system with Spring Boot and Json web token. I have a frontend app built with Angular. My understanding is that once authenticated, all API calls from the angular app will send the token to the server to be verified before a response is sent back.
I'm wondering then how Spring Security would fit into the picture. It seems like it is no longer necessary if I just use the server to verify the token every time the frontend makes a call.
My question is whether or not Spring Security is required in this instance and if it is, what role will/can it play?
I would like to know from the outset before diving in. Thanks!

I have to implement a OAUTH 2.0 server application , i know how oauth 2.0 works but when i have googled on how to implement, everywhere i am getting spring boot with oauth 2.0 and my requirement is i should give two URL's to the client
one to get the access_code and second rest call to get the access_token, is there a way that i can get this from spring boot or spring security ? in Memory storage for tokens.
I tried using spring boot oauth examples but none of them are giving separate URL's for access_code and access_token.
I think you mean you are delivering the API part:
* Client authenticates against an OAuth endpoint and gets an access token
* Client calls API with an access token
* API must validate access token
Typically you'll code the API - and use an out of the box Authorization Server for the OAuth endpoint
To answer your question properly it would help to know what type of client (partner back end / UI etc)
There will be a bunch of messages between client, API and Authorization Server - this post may give you some ideas:

I may be able to help you with the spring boot stuff once I understand your scenario better
I am building an application with an angular frontend and spring boot on the backend. I was able to configure the angular and spring part.
So, the frontend requests a token and sends it with every request to the java backend. This works just fine.
My java backend is now in the need to reuse the client token to request data from another service, which uses the same mechanism.
What is the right way to go forward? Requesting an own token for my service or using the existing token from the authenticated user?
I have not found a way to do this.
Works as pointed out by ravthiru
While calling your 3rd service you can use the same token , Add your third service as bearer-only Client.
I am working on securing a REST API, here is the basic set up (Happy Path) I am working with:
1) UI will request to authenticate with another service, this service will return a JWT to the UI.
2) Once a user of the UI is done with their work, they will make a request to the REST API that I am tasked with securing using a JWT that is passed to me.
3) I will then ensure the JWT is legit, get the users roles and then determine if the user is authorized to access that endpoint (perform the requested function).
I am sure this is possible, but my past experience with Spring Security wasn't dealing with JWT or Authorization only.
Would it be a correct approach to implement Authentication and Authorization, get that working and then back out the Authentication part?
Thank you for your kind help!
I suggest that you take a look at the Spring Security OAuth2 project. It makes this kind of thing fairly easy.
In particular, have a look at this section about using JWT
I need to create a SpringBoot RESTful API to be consumed either by a web project or a mobile app.
My question is how to secure it without the typically basic authorization that returns you a "jsessionid" to the web browser and mantains the session with it. It's not a problem for the web project, because it could store that jsessionid. But how about to secure the mobile app request to the API?
Sorry for my english. Thanks.
One of the architectural constraints of REST is that it must be stateless.
Your REST API must not have sessions that authenticate the client. Instead, the client should pass some sort of token, commonly placed in the Authentication HTTP Header.
JWT and OAuth 2.0 are both very popular ways of doing this, and you can absolutely use HTTP Basic Authentication with OAuth 2.0 if you wish.
Here's an article called Stateless Authenticaiton with Spring Security and JWT. Hopefully that will help!
You can use basic authentication. It work sending username and password on each request but don't need save the sessionid in the client.
Here are a sample application with basic authentication:
http://www.baeldung.com/spring-security-basic-authentication
If you don't save anything in the server session you don't need save the jsessionid in the client.
I am developing a RESTful web service as a back-end layer for mobile application. This service receives combination of device id (as user id) an a pin (as password), and passes to another back-end service, that validates and returns the status of successful login along the user information, in case, the user is authorized. My service is not validating the user. And mobile sends sub sequent requests to my RESTful service.
So, please suggest, how can I make all this system(especially the RESTful) secured, using Spring security.
I am using a Tomcat server, Spring and Jersey
I recently implemented a method to secure my existing RESTful APIs in Spring. I have used a token based authentication model using OAuth2. In my project, I wanted to secure my API's in a way that every request is individually authenticated and authorised based on the token present in the header. If this is something you are looking for, then I would highly recommend you to take a look at the documentation here. If there is anything you are stuck at while implementing it. Please do let me know.
Also, you can find multiple projects for Spring and OAuth here
