Spring Boot – How to solve OAuth2 REDIRECT_URI_MISMATCH


When trying to authenticate a user using OAuth2 through a third-party service like (Google, Facebook .. etc.), the following error occurs:



redirect_uri_mismatch error occurs when the redirect URL defined for your application at the authorization service doesn’t match with the value of parameter “redirect_uri” passed by your request.

When integrating OAuth2 with Spring Boot, the default value of redirect_uri is set to “<ip>:<port>/login”. 

In order to solve this issue, you have 2 options:

  1. Define “<ip>:<port>/login” as a redirect URL under the authorization service.
  2. Use a custom redirect URL through setting the following attributes in application.properties:

    In the above configuration we set a custom redirect URI as “http://localhost:9090/callback”.
