How to send data to Redis in ElastiCache

I already connected with Redis in ElastiCache, and I have a hashmap which contains some key value pairs, how can I send those key value pair to redis in java?

config.useReplicatedServers()            .addNodeAddress("redis://config-001.7gvixh.0001.usw2.cache.amazonaws.com:6379")            .addNodeAddress("redis://config-002.7gvixh.0001.usw2.cache.amazonaws.com:6379")            .addNodeAddress("redis://config-003.7gvixh.0001.usw2.cache.amazonaws.com:6379")RedissonClient redissonClient = Redisson.create(config)
