Spring boot setup:

1. Add credentials of app in the application.properties file

Add credentials of app

2. Add the Maven dependency to our pom.xml:

Add the Maven dependency to our pom

3. Next, we’ll create the AuthConfig class to read Auth0 properties from the application.properties file:

create the AuthConfig class to read Auth0 properties

create the AuthConfig class to read Auth0 properties1

4. Next, we’ll create AuthController class for the login and callback api and also we have to add get management Api method to generate the access token.

AuthController class

AuthController class1

5. Next we’ll add the Home Controller to home Api and welcome Api.

Home Controller to home Api

User Controller to create user

User Controller to create user1

8. Next we’ll create user dto for the create user.

create user dto for the create user
