spring-security-oauth2-client-example

Modules

minimal-sample

This module contains the minimal configuration required for a Spring Boot project using Spring Security with OAuth2 client.

custom-userservice-sample

Same as minimal-sample, but it contains a custom OAuth2 UserService.

Note

For Google, it's actually possible to just use the two following properties:

spring.security.oauth2.client.registration.google.client-id=
spring.security.oauth2.client.registration.google.client-secret=

But for the sake of the example, I'll be inserting all properties.

Creating the API credentials

• Navigate to Google's Developer console
• Create credentials > OAuth client ID

• Select Web Application
• Add http://localhost as Authorised JavaScript origins
• Add http://localhost/login/oauth2/code/google as Authorised redirect URIs

• Click on Create
• Copy your client ID and your client secret as the value for
  spring.security.oauth2.client.registration.google.client-id and
  spring.security.oauth2.client.registration.google.client-secret respectively in the application.properties file.
• Done
