I'm looking for a solution to add third-party provider OAuth2 flow like Facebook to my existing Spring OAuth2 authorization server and resource server using Spring Security which accept only password grant actually.
This work great with /oauth/token?grant_type=password&username=myuser&password=mypwd
Now, I need to understand how I can add provider OAuth flow, I tried many tutorials with Spring Social for example or with Filter to catch request but.. it's never for only API and/or never coupled with password grant and can't found how to do this, maybe I miss something ?
Again it's only for API, no need configure route /login? or so
If someone can explain me how to do this or github/tutorial example project ? Spring Social can help me here ?

I wrote a spring boot webapp with spring security authentication over jpa. It uses jwt to grant access to a simple html/js application.
I'd like to add oauth2 flow in order to allow users to authenticate over github or google or whatever cloud system.
What kind of solution may I adopt to target it?
I see many applications like udemy, for example, or others. They allow multiple authentication types:
username and password
google account
facebook account
How may I replicate this behaviour in my webapp?
I want to implement in backend rest safely in oauth2 + jwt.
I want to implement the following authentication flow in spring boot, but I am not sure how to do it:
1. The user is authenticated.
2. That request is received and with that login and password a ws that validates the credentials is attacked.
3. If it is correct, a series of data and permissions are searched in the database
4. If it is correct, access is granted and the jwt token is generated
I'm lost with this and as much as I read I can't know how I can do it.
Any manual or post I can follow?
Are you running your own (a custom) Auth server or is the plan to allow users to authenticate via a provider such as Google, Facebook etc? If its the later, then you cannot expect to receive user / password credentials at all so you might have misunderstood the OAuth flow. You will typically receive an 'Authorization code' from the provider (e.g. Google).
Also, what do you mean by "a ws that validates the credentials is attacked"?
This Google use-case diagram depicts a common flow. It's part of this guide.
Either way, Spring Boot does not itself deal with OAuth / security, but it has a tight
integration with Spring Security which is a good security framework to use, especially as you're already using Spring. Spring Security can handle OAuth, JWT etc.
A couple of guides that may help to get you started:

https://spring.io/guides/tutorials/spring-boot-oauth2/
I have a working Authorization Server and Resource Server implemented using Spring Security features that provide single sign-on to all the registered clients in my organization.
It supports the following grant type:
Authorization code for web application
Password
Implicit
Now, one of our new products is a single page application built using React. In order to authenticate and grant access token to it from our custom Auth Server, we are enhancing the Spring project to support PKCE grant type and also making sure the existing functionality does not break.
I know I need to use the latest Spring Security 5 classes of the artifact 'spring-security-oauth2-core', but I am not able to find any documentation around it or sample code example, to begin with.
Any pointers will be a great help.
Hi I am really new to Spring boot and Oauth2. I need to understand how to authenticate Spring boot web service with Oauth2 authentication with refresh token and access tokens. Likewise I need to know how to limit the access of different users (accessing resources) dynamically as well. I have searched in many articles on line and ended up with nothing that I really need to learn. I do not need SSO config with facebook or google. I want to know how to make our own authorization server.
Can anybody please help me to guide or send me a link of a useful tutorial that helps me to learn.
thank you.
This is a very open-ended question. So few links to start with:
Ok, start with OAuth2 Guide then OAuth2 Grant types. These are generic stuff you need to know.
Then In Spring Security OAuth 2 using Spring Boot .
You can basically restrict the API access in Resource Server by using a combination of OAuth scopes and Roles.
And finally, this is an amazing example which shows you how to manage OAuth clients, their grant types, tokens and so on.
Please get back with specific queries, it would be easier to help.
I've read about Oauth2 few days before, it has entities like Client, Resource Owner, Resource Server, Authorization Server and i understood the explanations too. but i don't understand the grant type's completely still i got confusion on following types. Oauth2 has 4 different grant types like,
Authorization code
Implict
Resource Owner Password Credentials
Client Credentials
please, give me some real time examples for the above types to differentiate the implementation. I need to know that what are the types of grant implementation spring security oauth2 has and full flow for spring oauth2 with security.
I have gone through some example implemented with oauth2 with spring mvc, spring security. but it's confusing me i don't get clear picture of the api implementation.
I'm looking for good Oauth2 flow and document with Spring mvc and Spring security. please help me.
In terms of understanding the flows and the differences between them, this presentation is the best resource I found online. After this, if you read the OAuth2 spec description, it'll be much easier to follow.
Unfortunately, in terms of code samples, there isn't good Spring Security OAuth2 sample code out there (the Sparklr and Tonr examples are okay but not super clear). Best resource there is to look at unit tests in Spring Security OAuth2 code on github.
One question I want to ask is - are you looking to create your own OAuth2 Provider or do you just want to connect to Facebook, Google, etc as OAuth2 client. If it's the second part, I would suggest skipping Spring Security OAuth2 and instead look at Spring Social project.
Edit:
For creating an OAuth2 Provider, check out this code by Dave Syer (he is the lead of Spring Security OAuth project) . It shows how you can create an OAuth2 Provider and Resource Server in 20 lines of code. This is the easiest way to create Spring Security OAuth code.
https://github.com/dsyer/sparklr-boot
It uses Spring Boot and Spring Security OAuth projects. Of course, you'll have to understand Spring Security, JavaConfig configuration and the OAuth2 protocol properly to understand how all of this works.
Authorization Code is redirection based flow, in most application when we login via Facebook or google we use this grant type.
Implicit is used mostly in mobile or single page application, Client confidentiality is not guaranteed here. This also has a redirect flow similar to Authorization Code. This does not support refresh token.
Password Grant Type is used when client application and resource owner belong to same application, this is goin to be case when your application is end to end working. Here we are sharing username and password. unlike the above two where we authenticate via Facebook or google.
Client Credentials: its a way to access it own service. like one microservice to access another microservice.
I also got into OAuth2 using spring last month.
I've read most of the OAuth2 spec and used the samples from the spring-security source, which are wonderful. That way I got a running application which I could use to play with and view it's sources next the the specs.
