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

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.
