I'd like to give users the option to login to a Spring Boot web application using their Google or Facebook account.
I checked The Spring Cloud Security documentation and also This GitHub issue to add such SSO functionality, but on both they only show how to configure one SSO server, so it's either Google or Facebook.
How can I add both options? on the web front-end I will add a button for each option so the users can choose which account to use, either Google or Facebook.
Or I am choosing the wrong package and should use something different altogether to achieve this?
Thanks!
You basically have to install a separate authentication filter for each provider. There's a tutorial here: https://spring.io/guides/tutorials/spring-boot-oauth2/.

What is the best way to integrate my Spring Boot app with OAuth2? It already has login functionality with issuing a JWT token. What I want to achieve: perform login using OAuth2 and issue the same JWT to access my app.
What should I use:
Keycloak auth server + make my app a resource server
Write my own auth server using spring-security-oauth2-autoconfigure and spring-boot-starter-oauth2-client + make my app a resource server?
Any other approach you can suggest...
Maybe, this link can help you: https://stackshare.io/stackups/keycloak-vs-spring-security
It really depends on your scenario.
But, in my opinion, the first option has more advantages. The main one is the maintenance effort. With your own oauth server, you must maintain one more service. Keycloak is mature and open source, with many developers maintaining it.
I've written a software system that uses Spring Cloud Netflix. Due to Spring Security 5 not offering support for writing an Authorization Server (pls shout out here https://github.com/spring-projects/spring-security/issues/6320) I need to write my own Authorization server. I want my application to permit Social login and username/password registration, have a custom login page but also use keycloack. I don't even know from where to start, if you have any documentations or code samples please provide.
You can use the cas project. By using the overlay it is easy to set up and to customize:
https://github.com/apereo/cas-overlay-template/blob/master/README.md
It serves a frontend where your user can be redirected to and can login. After successful login, the user is redirected back to your web page. The frontend is completely customizable.
It supports all kinda of authentication providers like keycloak, database or Google/Facebook.
After basic setup you just add the dependency inside the gradle file, configure your keycloak/database/... in the application.properties and can start using it as authentication server.
It fits perfect into a microservice landscape and is curated by professionals implementing security best practice.

I'm just wrapping my head on Oauth2. I have a Spring boot app with its own users and roles system handled by Spring Security 5. Internally I use email to identify users, I want people who registered with their gmail addresses to be able to log in through Oauth2. Or, more generally, how do I make one of my users log in to my app using Oauth2? If you need code or more information just ask. Thanks in advance.
As far as I understood your question, you are looking for a general approach to authenticate users for using your Spring Boot application with the help of OAuth2 protocol.
In your case you will probably use Google as an authentication provider and your application as resource server, according to the OAuth2 standard wording. First at all to answer your general question, there are different ways of using OAuth2 to authenticate users. A good starting points are these links:
https://www.rfc-editor.org/rfc/rfc6749
https://auth0.com
To find the proper way of implementing OAuth2 for your usecase I recommend using this decision tree: https://auth0.com/docs/api-auth/which-oauth-flow-to-use
For starting to implement OAuth2 in Spring Boot you can use several Spring Security projects with further documentation:
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-security.html#boot-features-security-oauth2
https://docs.spring.io/spring-security-oauth2-boot/docs/current-SNAPSHOT/reference/htmlsingle/
i have my web app builded with Angular 4/5 and Spring Boot. Now i want to add user-accounts to my app and there i have some problems. I would like have my Auth serwer (in Spring Boot) and also i want use providers like Facebook and Google. There is my first question, when user will choose Facebook to auth, then how my resource server will know who is asking for resource. When i use my own Auth serwer i am doing it like this:
#GetMapping("/user/name")
public ResponseEntity<String>(Principle principle) {
return new ResponseEntity<String>(principle.getName(), HttpStatus.OK);
}
and this is working, but how to get user username when user is using Facebook or Google auth?
My second questions is how to properly handle expire Tokens time in Angular 4.
My third and last questions. Some resources from my server will be availible for
not logged user(annonymous) so how can i protect my resources to prevent other's than my clients using my API?
If you have some advices or examples, please help!
Don't worry about the rude comment on your question, Single Sign-On (SSO) can be pretty complicated.
If your using Facebook and Google as optional SSO providers then what you have to realize is that those providers are going to give you some sort of unique identifier along side the user information when you request it.
Spring Security and the corresponding Spring Boot auto configuration has some pretty good support for linking SSO user information to a Principal. Ill add some good references below to help understand Springs solution for this. I'm going to assume Spring Boot 2 and Spring Security 5 since your versions aren't listed.

You can also look into Spring Social if your looking to do more than just SSO.
I have an app (A) exposing REST services secured with oauth2. (spring security oauth2/spring-web)
I want to create a second app (B) (spring-boot or normal spring), from where I can login then call the REST services from A.
How can I configure security in app B so I can use both social login (facebook, twitter, google) and call REST services from app A? Is there an example using spring security/oauth/social integration?
I've found some examples but none sais how to integrate them
Have you tries the Spring oAuth2 tutorial with FB and Google login? This also includes a local login. All code is available in git from the link in the right column of the tutorial.
