12.3. 初始化监听器

Redisson Node提供了在启动完成后，执行RedissonNodeInitializer指定的初始化监听器的机制。这个机制可以用在启动完成时执行注册在类路径（classpath）中分布式远程服务的实现，或其他必要业务逻辑。比如，通知其他订阅者关于一个新节点上线的通知：

public class MyRedissonNodeInitializer implements RedissonNodeInitializer {
    @Override
    public void onStartup(RedissonNode redissonNode) {
        RMap<String, Integer> map = redissonNode.getRedisson().getMap("myMap");
        // ...
        // 或
        redisson.getRemoteService("myRemoteService").register(MyRemoteService.class, new MyRemoteServiceImpl(...));
        // 或
        reidsson.getTopic("myNotificationTopic").publish("New node has joined. id:" + redissonNode.getId() + " remote-server:" + redissonNode.getRemoteAddress());
    }
}
