默认

#系统默认连接池,这种方式 redisTemplate 可直接使用默认，在使用的地方直接注入即可
spring.redis.cluster.nodes=192.168.100.1:6379,192.168.100.1:6380,192.168.100.2:6379,192.168.100.2:6380,192.168.100.3:6379,192.168.100.3:6380

spring.redis.poll.max-idle=8
spring.redis.pool.max-wait=-1
spring.redis.pool.min-idle=0
spring.redis.timeout=6000

@Autowired
    private RedisTemplate<String, String> redisTemplate;

jedis

#使用jedis连接池,需要连接池注入配置信息,在使用的地方直接注入即可

        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new StringRedisSerializer());
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        return redisTemplate;
    }

}

@Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @RequestMapping("/hello")
    public Object hello() {

        Object result = redisTemplate.opsForValue().get("1");
        return result;
    }

#使用lettuce连接池,需要连接池注入配置信息,在使用的地方直接注入即可
spring.redis.cluster.nodes=192.168.100.1:6379,192.168.100.1:6380,192.168.100.2:6379,192.168.100.2:6380,192.168.100.3:6379,192.168.100.3:6380
