"Redis" Jedis client implementation Redis message publishing subscriptions (real-time messaging middleware)

Publish

Import Java.io.BufferedReader;

Import Java.io.InputStreamReader;
Import Org.slf4j.Logger;

Import Org.slf4j.LoggerFactory;

Import Redis.clients.jedis.Jedis;

	public class Redispublisher {private static final Logger log = Loggerfactory.getlogger (Redispublisher.class);

	Private final string[] channel;

			try {bufferedreader br = new BufferedReader (new InputStreamReader (system.in));
				while (true) {String line = Br.readline (); if (!) Quit ". Equals (Line)} {for (int i = 0; i < Channellen i++) {if (Channel[i].matches (" ^chiwei.* ")) {L
							Og.debug ("Match ...");
						Pubjedis.publish (Channel[i], line + "haha");
					else {pubjedis.publish (channel[i], line);	} log.debug ("Publish to {}", channel[i]);
				} else {break;
		(Exception e) {log.error (IO fail while reading input, e);
 }
	}
}

The above published class, the published channel is an array, that is, the content published to multiple channels, you can judge according to the content, different content published to different channels.

 }

}

This class is the implementation of the subscription class, for the various operations of the subscription to achieve specific processing methods.

		Jedispool.returnresourceobject (Subjedis);
		Jedispool.returnresourceobject (Pubjedis);
	Jedispool.close ();
 }

}

Subjedis.psubscribe (Sub, "^chiwei.*"); Channel with regular matching subscriptions

Because the subscription class blocks execution of the current thread, a second thread in the main thread starts the subscription, and then launches the publishing thread to publish the content.
