### 场景 ###

*  springboot集成redis集群 检查key时发现key是二进制格式的 \\xac\\xed\\x00\\x05t\\x00\\x0eHAOKE\_HOT\_WORD

### 分析 ###

RedisTemplate<K, V>模板类在操作redis时默认使用JdkSerializationRedisSerializer来进行序列化

### 解决 ###

1.  序列化方式切换成StringRedisSerializer
2.  通过配置bean的方式配置

## RedisClusterConfig.java
    @Configuration
    public class RedisClusterConfig { 
        @Autowired
        private ClusterConfigurationProperties clusterConfigurationProperties;
    
        @Bean
        public RedisConnectionFactory redisConnectionFactory(){ 
            RedisClusterConfiguration clusterConfiguration = new RedisClusterConfiguration(clusterConfigurationProperties.getNodes());
            clusterConfiguration.setMaxRedirects(clusterConfigurationProperties.getMaxRedirects());
            return new JedisConnectionFactory(clusterConfiguration);
        }
    
        @Bean
        public RedisTemplate<String,String> redisTemplate(RedisConnectionFactory redisConnectionFactory){ 
            RedisTemplate<String,String> redisTemplate = new RedisTemplate<>();
            redisTemplate.setConnectionFactory(redisConnectionFactory);
            redisTemplate.setKeySerializer(new StringRedisSerializer());
            redisTemplate.setValueSerializer(new StringRedisSerializer());
            redisTemplate.afterPropertiesSet();
    
            return redisTemplate;
        }
    }
    
    ### ClusterConfigurationProperties.java
    @Configuration
    @ConfigurationProperties(prefix = "spring.redis.cluster")
    @Data
    public class ClusterConfigurationProperties { 
        private List<String> nodes;
    
        private Integer maxRedirects;
    }
