基于redis(订阅发布)实现python和java进程间通信

主要结构为: python进程发布消息，java进程订阅消息。

依赖环境:

python:   pip install redis

java:  jedis

1. python端:

PubSub.py

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import redis   class 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

?

1 2 3 4 5 6 7 8 9

from PubSub import PubSub   obj = 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);
    }
}
