redis集群之哨兵模式

redis集群之哨兵模式

1、集群部署

安装配置可参考一下地址：
https://www.cnblogs.com/zhoujinyi/p/5569462.html

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](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<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);
	}
}
