Using threadlocal to bind instance of a class to a thread

Question

I have some difficulty in understanding the use of ThreadLocal in the below declaration. Does it mean, even though the instance is declared as static each thread will have it's own instance of DomainEventPublisher class

private static final ThreadLocal<DomainEventPublisher> instance = new ThreadLocal<DomainEventPublisher>() {
        protected DomainEventPublisher initialValue() {
            return new DomainEventPublisher();
        }
};

Provided you call `instance.get()` in each thread, yes. – Andy Turner Oct 07 '15 at 14:13 — Andy Turner, Oct 07 '15 at 14:13

Yes, that is exactly what ThreadLocal is for.

In your example, each thread will have a different instance of DomainEventPublisher
