How to implement Role Permission based system in Spring Boot

06:40 07 Jul 2016

I am trying to implement role permissions based system using spring boot and spring security. For this, I have taken an example from http://www.baeldung.com/role-and-privilege-for-spring-security-registration , but failed to do that.

There some etc. classes also there, but I am not posting due to large segment, if anyone requires specifics, I will post.

When I tried to run, I am getting following error on console:
