Missing @EnableReactiveMethodSecurity

[RalfLackinger]

First off thank you for this great example.

I think you forgot to add the @EnableReactiveMethodSecurity annotation on your SecuredRestApplication. I was playing around a bit with your code and removing the ADMIN role from the user setup did not prevent me from accessing the /api/admin endpoint.

@Bean
public MapReactiveUserDetailsService userDetailsRepository() {
	UserDetails user = User.withDefaultPasswordEncoder()
	                       .username("user")
	                       .password("user")
	                       .roles("USER")
	                       .build();
	return new MapReactiveUserDetailsService(user);
}

Then I generated a new token Bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyIiwicm9sZXMiOiJST0xFX1VTRVIiLCJpc3MiOiJyYXBoYS5pbyIsImV4cCI6MTU2NzY3OTY3OX0.C67PZ_YX2Zm1_YDMnVgqoxNXCEd4iKOhTM9EdiEA5WI (content can be checked via https://jwt.io/ and verified with the default secret of your app).

This will then still allow me to call the admin endpoint:

$ http -v :8080/api/admin "Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyIiwicm9sZXMiOiJST0xFX1VTRVIiLCJpc3MiOiJyYXBoYS5pbyIsImV4cCI6MTU2NzY3OTY3OX0.C67PZ_YX2Zm1_YDMnVgqoxNXCEd4iKOhTM9EdiEA5WI"

    {
        "message": "Hello Admin!",
        "name": "Admin"
    }
]

When adding the @EnableReactiveMethodSecurity annotation, I get the following, as expected:
