spring配置redis 哨兵模式

在Spring中配置Redis哨兵模式，需要使用JedisConnectionFactory，并设置相应的哨兵配置。具体步骤如下：

1. 引入相关依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.6.0</version>
</dependency>

2. 在application.properties中配置Redis哨兵模式相关信息：

spring.redis.sentinel.master=your-master-name
spring.redis.sentinel.nodes=host1:port1,host2:port2,host3:port3

3. 创建JedisConnectionFactory并设置哨兵配置：

@Configuration
public class RedisConfig {

    @Value("${spring.redis.sentinel.master}")
    private String masterName;

    @Value("${spring.redis.sentinel.nodes}")
    private String sentinelNodes;

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration()
                .master(masterName)
                .sentinel(sentinelsFromString(sentinelNodes));
        return new JedisConnectionFactory(sentinelConfig);
    }

    private Set<RedisNode> sentinelsFromString(String nodes) {
        Set<RedisNode> sentinelNodes = new HashSet<>();
        for (String node : nodes.split(",")) {
            String[] parts = node.split(":");
            sentinelNodes.add(new RedisNode(parts[0], Integer.parseInt(parts[1])));
        }
        return sentinelNodes;
    }
}
