Hi @callicoder
When I add config @EntityScan(basePackageClasses = {Jsr310JpaConverters.class}) to Application class.

and add method init(). The bellow error has occurred. And not started Tomcat.

@PostConstruct
void init() {
        TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
    }

org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name 'securityConfiguration': Unsatisfied dependency expressed through field 
'userDetailsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:

I have solved. Because I forgot to add Application.class to @EntityScan.
When login perform error has occurred.

Can't cast String to UserPrincipal in the method generaterToken();
