Examples of org.springframework.messaging.simp.user.DefaultUserDestinationResolver

org.springframework.messaging.simp.user.DefaultUserDestinationResolver
A default implementation of {@link UserDestinationResolver} that relieson the {@link org.springframework.messaging.simp.user.UserSessionRegistry}provided to the constructor to find the sessionIds associated with a user and then uses the sessionId to make the target destination unique.
When a user attempts to subscribe to "/user/queue/position-updates", the "/user" prefix is removed and a unique suffix added, resulting in something like "/queue/position-updates-useri9oqdfzo" where the suffix is based on the user's session and ensures it does not collide with any other users attempting to subscribe to "/user/queue/position-updates".
When a message is sent to a user with a destination such as "/user/{username}/queue/position-updates", the "/user/{username}" prefix is removed and the suffix added, resulting in something like "/queue/position-updates-useri9oqdfzo". @author Rossen Stoyanchev @since 4.0
