spring-redis-publisher-demo

A minimal Spring Boot demo of a Redis PubSub publisher implementation

See https://github.com/gewure/spring-redis-subscriber-demo for the subscriber

Run

start REDIS on localhost:

redis.cli

get into SYNC Mode to monitor if everything works:

SYNC

start both applications, go to PublisherService API, localhost:8080/msg and submit a message like:

http://localhost:8080/msg?msg=test&sender=test

if everything works you should see this in the Subscriber:

Message received: SomeMessageClass(id=33f82f42-5d94-4a35-afcf-be2d2bd507ec, sender=test, message=test, timestamp=1607357572787)

and something like this in Redis:

127.0.0.1:6379> SYNC
Entering replica output mode...  (press Ctrl-C to quit)
SYNC with master, discarding 178 bytes of bulk transfer...
SYNC done. Logging commands from master.
