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.
