redis主从基于sentinel哨兵项目文件配置(基于springboot)

1. 两种方式: 一种是基于yml方式,一种是基于java config
2. 基于maven的pom依赖,哨兵模式在redisson版本>=3.12.5和<3.15.0有问题,项目启动的时候会报错Command execution timeout for command: (SENTINEL SENTINELS) :
   https://github.com/redisson/redisson/issues/3404
   like #3283
   through the test,:
   this not happen in 3.12.4
   this will happen in 3.12.5 or higher
   My current version is 3.15.0, and I use this configuration so that it doesn’t report errors:

            <dependency>
                <groupId>org.redisson</groupId>
                <artifactId>redisson-spring-boot-starter</artifactId>
                <version>3.12.4</version>
            </dependency>

3. yml的配置方式:

spring:
 redis:
   redisson:
     # 配置模式
     config: classpath:redisson-sentinel.yml
           
redisson-sentinel.yml中的内容:

sentinelServersConfig:
 idleConnectionTimeout: 10000
 connectTimeout: 5000
 timeout: 5000
 retryAttempts: 3
 retryInterval: 1000
 password: 1234
 subscriptionsPerConnection: 200
 clientName: null
 loadBalancer: ! {}
 slaveConnectionMinimumIdleSize: 5
 slaveConnectionPoolSize: 250
 masterConnectionMinimumIdleSize: 5
 masterConnectionPoolSize: 250
 readMode: "SLAVE"
 subscriptionMode: SLAVE
 # 26379 26380 26381是sentinel中的端口,不是redis的端口
 sentinelAddresses:
   - "redis://127.0.0.1:26379"
   - "redis://127.0.0.1:26380"
   - "redis://127.0.0.1:26381"
   - #masterName是sentinel中定义的sentinel monitor 
 masterName: "bidMaster"
 database: 0
threads: 0
codec: ! {}
eventLoopGroup: null 
     

4. 基于java config的方式:

配置文件:
 redisson:
   database: 0
   password: '1234'
   #2、哨兵模式
   master-name: bidMaster
   sentinel-addresses:   
     - "redis://127.0.0.1:26379"
     - "redis://127.0.0.1:26380"
     - "redis://127.0.0.1:26381"
   
 
java config类:
