spring-boot-oauth2 | Spring boot User Registration and OAuth2 Social login | Authentication library

I have followed a Spring Boot tutorial Spring Boot and OAuth2 that has had the curl command to start the project:

But this curl command doesn't work. When I changed the command adding -o file_name parameter, it downloaded an empty file. I also create a listing of curl verbose mode. How to make curl work? Here are the commands in the terminal:

So I cant seem to wrap my head around this...

What could possibly the reason for this?

My settings:

Im using Spring Boot 2.3.3 in Combination with Vaadin 17.0.3. For oauth i use Spring-Boot-Oauth2. (Pretty much this tutorial: "https://vaadin.com/learn/tutorials/google-login")

It worked on Vaadin 14 but i guess after switching to Vaadin 16 something broke... Im trying to test some things, but a rollback isnt that easy for me rn.

My JDK is Java 14.

When Im trying to click on one of my OAuth Links, e.g. "/oauth/authorization/google" , my applicationr returns a 404. But when I enter the same link in the browser it works.

I dont know where to start, but I suspect it has to do something with Vaadins RouterLayout.

Any ideas what might cause this? I cant post code, since I dont know where the error could be...

If you need more information feel free to ask.

I have existing Spring Boot application with Spring Security 5 and OAuth2 client, I've successfully configured authentication with external OAuth2 provider (GitLab, in my case).

Now I have problem with configuring authorization. I'd like to have some method that would let me write code to resolve roles for given user (either by making a call to the database or just checking hard-coded username).

I've found out that it could be achieved by using PrincipalExtractor and AuthoritiesExtractor, described in a nice article. However, those classes are no longer present in recent Spring Security. What is an alternative way to achieve that, compatible with Spring Security 5?

I want to authenticate users with an external OAuth provider in my reactive spring boot application.

Following the official tutorial, I successfully implemented the flow with the pre-configured providers (Google, Github, etc.). Changing the configuration to not-pre-configured providers can be done using these properties, e.g.:

I'm trying to include a 'third-party' url in a vaadin 14 + spring boot application, namely the redirect url of spring-security for a single-sign on '/oauth2/authorization/github'. However the vaadin servlet seems to intercept this url and shows an error message that the route is unknown.

Could not navigate to 'oauth2/authorization/github'

Reason: Couldn't find route for 'oauth2/authorization/github'

How can this be prevented so the oauth2 url can be reached? I checked the vaadin documentation but found no information on how to exclude particular paths from the regular router navigation mechanism. The spring-boot oauth2 tutorial is from the official spring site https://spring.io/guides/tutorials/spring-boot-oauth2/ and the following dependencies were added:

I have Spring Boot OAuth2 server working, but now we need to distinguish between different clients from different departments and provide different functionality depending on the department. I figure I can separate it by the client id. This guide shows how to set up the OAuth2 server with a single client id, but how do I set it up with multiple client ids?

https://spring.io/guides/tutorials/spring-boot-oauth2/#_social_login_authserver

And then, when an API request is made, how do I find out which client id it is?

I'm learnig spring security and I came across this piece of code from https://spring.io/guides/tutorials/spring-boot-oauth2/

I have been searching for the best way to build an application using Angular 4 (client application running over apache2), Spring Boot (Rest Controller) and Social and Local login.

I am kinda new to all of this, and I've be looking around for about one month and still have not a good idea how to implement that! Couldnt find a good tutorial for the tecnologies mentioned above...

I need to be able to let the user login via system's own login and social login like facebook and google. Could someone please point at the right direction?

I am not sure if that I am on the right track... I thought that would be easy, but I feel very confuse and dont see how to integrate the response from spring with my angular application. And the login with social networks will not be direct with the angular application. The user will authenticate with facebook, for example, and when facebook redirect to spring, Ill retrieve the user associated to that social networks account and return that to my angular application. In the angular 4 application, Ill should be possible to invite friends and use some other social networks related features.

Here are some of the tutorials i've read: http://www.baeldung.com/angular-4-upgrade-for-spring-security-oauth/ https://spring.io/guides/tutorials/spring-boot-oauth2/#_social_login_click

Can someone help me, pointing to the right direction, or placing a good tutorial or anything that would help?

I have an autherization server which built with Spring 1.5.7 and it was working fine. Now when I tried to move to Spring 2 this is working. I have also followed all the steps of https://spring.io/guides/tutorials/spring-boot-oauth2/ with no luck. Problem is that when I use it without context-path it works fine like http://localhost:8080/oauth/token but when I use a context path it is not able to authenticate like http://localhost:8080/auth/oauth/token . This was working in the older version of Spring boot i.e. 1.5.7 but with Spring boot 2.1.8 which i tried it is not working. Any help please
