Spring Boot 3.0 Facebook Login

Purpose

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:

Software version

Java 17

spring boot 3.0.1

spring security 6

thymeleaf-extras-springsecurity6

Github Source Code

https://github.com/chuangtc/spring-boot-3.0-facebook-login

Folder structure

Maven Configuration

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

The Facebook Properties yml file

Next, let’s configure Facebook properties in our application.yml:

  security:
    oauth2:
      client:
        registration:
         facebook:
          clientId: YOUR_APP_ID
          clientSecret: YOUR_APP_SECRET
          scope:
           - email
           - public_profile

Conclusion

In this quick article, we learned how to use spring-boot-starter-security to implement a secondary authentication flow for our application.
