redisson 哨兵模式配置

背景：项目redis由集群改为哨兵模式，漏洞扫描未授权访问漏洞（CNVD-2019-21763），要求对redis哨兵也设置密码，redisson依赖版本为3.11.5   spring-boot版本为2.1.13。

redisson依赖升级

        <dependency><groupId>org.redisson</groupId><artifactId>redisson-spring-boot-starter</artifactId><version>3.15.6</version><exclusions><exclusion><groupId>org.redisson</groupId><artifactId>redisson-spring-data-24</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.redisson</groupId><artifactId>redisson-spring-data-21</artifactId><version>3.15.6</version></dependency>

        说明：3.11.5版本不支持设置哨兵密码，也就是SentinelPassword，需要升级redisson版本，为什么排除redisson-spring-data-24，高版本redisson会排除jedis以及lettuce，如果不排除并重新引入的话启动会报错，报错如下：java.lang.NoClassDefFoundError:org/springframework/data/redis/connection/RedisStreamCommands

2.1.X版本支持的是redisson-spring-data-21，所以排除springboot2.3的支持，引入2.1的支持。

配置：

spring.redis.database=0
spring.redis.password=HcicloudRedis2000
spring.redis.sentinel.master=mymaster
spring.redis.sentinel.nodes=ip:portspring.redis.jedis.pool.max-idle=200
spring.redis.jedis.pool.min-idle=10
spring.redis.jedis.pool.max-active=200
spring.redis.jedis.pool.max-wait=10000ms
spring.redis.jedis.pool.ping-rate=30000
spring.redis.jedis.pool.timeout=10000

config:
