how to secure springboot rest apis using auth0 oauth2 scopes

securing a spring boot rest api using auth0 with oauth2 scopes is a powerful way to manage access control. in this tutorial, we will walk through setting up a spring boot application that integrates with auth0 for authentication and authorization using oauth2 scopes.

prerequisites

1. **java development kit (jdk)**: make sure you have jdk 8 or higher installed.
2. **maven**: make sure you have apache maven installed.
3. **spring boot**: basic knowledge of spring boot.
4. **auth0 account**: sign up for a free auth0 account if you don't have one.

step 1: create an auth0 application

1. log in to your auth0 dashboard.
2. create a new application by clicking on "applications" and then "create application".
3. choose the "regular web applications" option and give it a name.
4. choose "create".
5. in the settings of your application, note down the following:
- domain
- client id
- client secret

step 2: create api scopes

1. navigate to the "apis" section in the auth0 dashboard.
3. click on the "settings" tab and add scopes that you want to use (e.g., `read:messages`, `write:messages`).

step 3: create a spring boot application

3.1. initialize a spring boot project

- spring web
- spring security
- spring boot devtools
- spring oauth2 client

3.2. project structure

your project structure should look similar to this:

step 4: configure application properties
