For example, the following class defines a listener to print out some information every time a new entry is added to the cache:  @Listener public class PrintWhenAdded {   @CacheEntryCreated  public void print(CacheEntryCreatedEvent event) {    System.out.println("New entry " + event.getKey() + " created in the cache");  }  }  For more comprehensive examples, please see the Javadocs for @Listener.
