Redis disconnect how to reconnect? This problem may be often encountered in our daily work. This article mainly discusses the solution of redis disconnection and reconnection. There is a certain reference value, friends in need can refer to, hope to help you.

After the Redis is restarted, the network disconnects and returns to normal, the application must be able to recover itself. Take the jedis client in Java language as an example:

1. As a publisher

The Jedis object cannot be used as a singleton, and the Jedis object cannot recover itself after the network flash is broken. Each time a message is published, the Jedis object is fetched from the JedisPool and the set method is called.

2. As a subscriber

When the network flash breaks, the psubscribe () method no longer blocks and throws an exception, so you can use the while loop to handle the exception inside the loop, as follows:

While (true) {Jedis redis = this.jedisPool.getResource (); try {redis.psubscribe (this, channelArray);} catch (JedisConnectionException e) {logger.warn ("Exception:", e); logger.warn ("Exit redis psubscribe, retry after 1 second") } catch (Exception e) {logger.error ("Exception:", e);} try {Thread.sleep (1000);} catch (Exception unused) {} try {if (redis! = null) {redis.close () }} catch (Exception unused) {}}
