## redis集群之哨兵模式 ##

1、集群部署

安装配置可参考一下地址：

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=0
    spring.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
    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<Object,Object> redisTemplate;
    	
    	public void set(String key, String value){
    		ValueOperations<String, String> 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);
    	}
    }
