Implementation of Python and Java interprocess communication based on Redis (subscription release)

The main structure is: The Python process publishes messages, and the Java process subscribes to messages.

Dependent environment:

Python:pip Install Redis

Java:jedis

1. Python side:

pubsub.py

Import Redisclass PubSub (object):    def __init__ (self, host, port, db):        self.__conn = Redis. Redis (host, port, DB)    def publish (self, Channel, msg):        self.__conn.publish (channel, msg)        return True    def subscribe (self, channel):        pub = Self.__conn.pubsub ()        pub.subscribe (channel)        Pub.parse_response ()        return Pub

sub.py

From PubSub Import pubsubobj = PubSub (' localhost ', 6379, 1) redis_sub = obj.subscribe (' cord ') while True:    msg = REDIS_SU B.parse_response ()    msg = Msg[2].decode ()    print (msg)

2. Java side

Redispub.java

Import redis.clients.jedis.jedis;import java.util.date;public class redispub {    private static Jedis Jedis = new Jedis ("localhost", 6379);    Private static final String channel = "cord";    public static void main (string[] args) {String message = new Date (). toString (); Jedis.publish (channel, message) ; }}
