In this tutorial, I’d love to share with you guys about implementing social login with Facebook for an existing Spring Boot web application, using Spring OAuth2 Client library – so your users will be able to sign in your application using their own Facebook accounts instead of application-managed credentials.
Suppose that you have an existing Spring Boot project with authentication functionality already implemented using Spring Security and the user information is stored in H2 in-memory database.
Then we will update the login page that lets the users login using their own Facebook accounts like this:
spring boot 3.0.1
spring security 6
Github Source Code
The Facebook Properties yml file
Next, let's configure Facebook properties in our application.yml:
In this quick article, we learned how to use spring-boot-starter-security to implement a secondary authentication flow for our application.
