7.2. Listener Example

The following example defines a listener in JBoss Data Grid that prints some information each 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");
  }
}
