anchor.diff:  In order to register a listener you have to implement an interface `org.springframework.cloud.zookeeper.discovery.watcher.DependencyWatcherListener` and register it as a bean.
   The interface gives you one method:
   
  -----
  -    void stateChanged(String dependencyName, DependencyState newState);
  +[source,java,indent=0]
  +----
  +void stateChanged(String dependencyName, DependencyState newState);

   If you want to register a listener for a particular dependency then the `dependencyName` would be the discriminator for your concrete implementation. `newState` will provide you with information

  Let's take a closer look at an example of dependencies representation:

  Zookeeper Config may be customized using the following properties:
