Java CommandLineRunner won't add roles to users

I'm follow a tutorial on Spring Boot Security, but I got stuck. Currently I'm setting up a CommandLineRunner, which does 3 things:
- Create Roles
- Create User
- Add roles to users
Running the code creates a table with the created roles and a table for the created users, but adding roles to users ends up in a error. I checked the code several times but cant find a mistake.

Please check out my code on Github and below you find the Stack overflow . Please let me know if you found something.

I found out that my application.properties ddl-auto was set to;

Code: 
spring.jpa.hibernate.ddl-auto=update

instead of;

Code: 
spring.jpa.hibernate.ddl-auto=create

This creates User duplicates every time I re-run my code. The code would not know to which User duplicate to add the Role to.
Stupid, learn for my mistake.

Good you found it, and thanks for posting the solution.
Given that non-unique results cause an exception in the code, you'd think that create would be the default value rather than update . Or so it seems to me. Unless it was, and you had changed it ?
