无法连接 elasticache 未知主机

Question

我的项目有下一期。

我想连接我的 AWS-elasticache，但这是不可能的

这是我的配置。

@Configuration
@ComponentScan
@EnableJpaRepositories
@EnableRedisRepositories
public class RedisConfig {

    @Bean// to use in my local machine
    @ConditionalOnProperty(prefix = "redis", name = "cluster", havingValue = "not")
    public LettuceConnectionFactory redisConnectionFactory(@Value("${redis.host}") String host,
                                                       @Value("${redis.port}") Integer port,
                                                       @Value("${redis.password}") String password) {
        RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration(host, port);
        configuration.setPassword(password);
        return new LettuceConnectionFactory(configuration);
    }

    @Bean// configure to elasticaceh
    @ConditionalOnProperty(prefix = "redis", name = "cluster", havingValue = "yes", matchIfMissing = true)
    public LettuceConnectionFactory redisClusterConnectionFactory(@Value("${redis.host}") String host,
                                                              @Value("${redis.port}") Integer port) {
        RedisClusterConfiguration clusterConfiguration = new RedisClusterConfiguration();
        clusterConfiguration.clusterNode(host, port);
        return new LettuceConnectionFactory(clusterConfiguration);
}

    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory connectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setDefaultSerializer(new GenericJackson2JsonRedisSerializer());
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setConnectionFactory(connectionFactory);
        return template;
    }

    @Bean
    @Qualifier("cacheManageMaster")
    public CacheManager cacheManager(LettuceConnectionFactory connectionFactory) {
        Duration expiration = Duration.ofHours(24);
        RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory).cacheDefaults(
                RedisCacheConfiguration.defaultCacheConfig()
                        .disableCachingNullValues()
                        .serializeValuesWith(
                                RedisSerializationContext.SerializationPair.fromSerializer(
                                        new GenericJackson2JsonRedisSerializer()
                                )
                        ).entryTtl(expiration)
        ).build();
        redisCacheManager.setTransactionAware(false);
        return redisCacheManager;
    }
}

但是我得到了一个例外，这里 stackTrace

spring boot 3.0.0版本

我尝试连接 RedisInsight 并且有效

我检查了一些看起来非常相似的问题，但对我没有任何帮助 https://github.com/redisson/redisson/issues/1625 https://github.com/sixthpoint/spring-boot-elasticache-redis-tutorial/blob/master/src/main/java/com/sixthpoint/spring/boot/elasticcache/redis/config/RedisConfig.java https://levelup.gitconnected.com/how-to-connect-to-aws-elasticache-redis-in-spring-boot-app-9dd2e0908467 https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/#cluster https://github.com/netty/netty/issues/8261

你知道有谁能解决这个问题吗？
