redis集群之哨兵模式
1、集群部署 
2、与springboot集成 这里哨兵模式暂时只提供了故障自动转移等，暂时不提供负载均衡功能，自动提供了故障转移和主从复制功能
配置
spring.redis.database=0spring.redis.password=123456# pool settings ...池配置 spring.redis.pool.max-idle=8 spring.redis.pool.min-idle=0 spring.redis.pool.max-active=8 spring.redis.pool.max-wait=-1 #哨兵监听redis server名称spring.redis.sentinel.master=mymaster#哨兵的配置列表spring.redis.sentinel.nodes=192.168.12.194:26379,192.168.12.194:36379,192.168.12.194:4637
调用封装
[@Component](https://my.oschina.net/u/3907912)public class RedisComponent { @Autowired //操作字符串的template，StringRedisTemplate是RedisTemplate的一个子集 private StringRedisTemplate stringRedisTemplate; @Autowired // RedisTemplate，可以进行所有的操作 private RedisTemplate redisTemplate; public void set(String key, String value){ ValueOperations ops = this.stringRedisTemplate.opsForValue(); boolean bExistent = this.stringRedisTemplate.hasKey(key); if (bExistent) { System.out.println("this key is bExistent!"); }else{ ops.set(key, value); } } public String get(String key){ return this.stringRedisTemplate.opsForValue().get(key); } public void del(String key){ this.stringRedisTemplate.delete(key); } public void sentinelSet(User user){ String key = null; try { key = new String(user.getId().getBytes("gbk"),"utf-8"); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(key); redisTemplate.opsForValue().set(key, user.toString()); } public String sentinelGet(String key){ return stringRedisTemplate.opsForValue().get(key); }}
