Question

springboot1.5.9采用lettuce方式连接redis集群，redis为集群模式，无法自动刷新拓扑结构而导致当master宕机主从切换期间Lettuce连接Redis报错的问题。

springboot1.5.9集成的spring-data-redis的版本是1.8.9，我没有找到配置自动刷新的接口；网上的文章基本都是springboot2.0以上的，对应的spring-data-redis版本也是2.0以上的，有配置的自动刷新的接口；所以请各位帮忙分析分析，springboot1.5.9采用lettuce的方式如何配置redis集群模式下拓扑自动刷新的问题！

这是我的配置代码

public class RedisConfig {

    @Autowired
    private RedisProperties redisProperties;

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        RedisConnectionFactory connectionFactory = null;
        if (redisProperties.getClusterMode().equals("true")) {
            //jedis
            //connectionFactory = new JedisConnectionFactory(redisClusterConfiguration(), jedisPoolConfig());
            //lettuce
            connectionFactory = new LettuceConnectionFactory(redisClusterConfiguration());
            ((LettuceConnectionFactory) connectionFactory).setTimeout(redisProperties.getTimeout());
            if(StringUtils.isNotEmpty(redisProperties.getPassword().trim())){
                ((LettuceConnectionFactory) connectionFactory).setPassword(redisProperties.getPassword());
            }
        } else {
            connectionFactory = redisStandaloneConfiguration();
            ((JedisConnectionFactory) connectionFactory).setTimeout(redisProperties.getTimeout());
            if(StringUtils.isNotEmpty(redisProperties.getPassword().trim())) {
                ((JedisConnectionFactory) connectionFactory).setPassword(redisProperties.getPassword());
            }
        }
        return connectionFactory;
    }

    private JedisConnectionFactory redisStandaloneConfiguration() {
        JedisConnectionFactory redisStandaloneConfiguration = new JedisConnectionFactory();
        redisStandaloneConfiguration.setHostName(redisProperties.getHosts());
        redisStandaloneConfiguration.setPort(redisProperties.getPort());
        redisStandaloneConfiguration.setPoolConfig(jedisPoolConfig());
        redisStandaloneConfiguration.setUsePool(true);
        return redisStandaloneConfiguration;
    }

    private RedisClusterConfiguration redisClusterConfiguration() {
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(
                Arrays.asList(StringUtils.split(redisProperties.getHosts(), ",")));
        redisClusterConfiguration.setMaxRedirects(redisProperties.getMaxRedirects());
        return redisClusterConfiguration;
    }

    private JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxWaitMillis(redisProperties.getMaxWait());
        jedisPoolConfig.setMaxIdle(redisProperties.getMaxIdle());
        jedisPoolConfig.setMinIdle(redisProperties.getMinIdle());
        jedisPoolConfig.setMaxTotal(redisProperties.getMaxTotal());
        jedisPoolConfig.setTestOnBorrow("true".equals(redisProperties.getTestOnBorrow()));
        return jedisPoolConfig;
    }

    @Bean
    public RedisTemplate<?, ?> getRedisTemplate() {
        @SuppressWarnings("rawtypes")
        RedisTemplate<?, ?> redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        // string序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        // 使用Jackson2JsonRedisSerialize 替换默认序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(stringRedisSerializer);
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

我自己看了spring-data-redis 1.8的源码，没有找到配置的地方；请各位大拿帮忙分析分析，springboot1.5.9采用lettuce的方式如何配置redis集群模式下拓扑自动刷新的问题！
