基於redis(訂閱發布)實現python和java處理序間通訊

標籤：cal   python   res   while   private   logs   highlight   decode   div   

主要結構為: python進程發布訊息，java進程訂閱訊息。

依賴環境:

python:   pip install redis

java:  jedis

1. python端:

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_sub.parse_response()    msg = msg[2].decode()    print(msg)

2. java端

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);    }}
