今天使用springdboot操作Redis时，发现key值出现 \xac\xed\x00\x05t\x00\tb，但不影响程序读写，查询资料发现redisTemplate 默认的序列化方式为 jdkSerializeable, StringRedisTemplate的默认序列化方式为StringRedisSerializer

可以通过手动配置, 将redisTemplate的序列化方式进行更改。
添加javaBean

/**
     * redisTemplate 序列化使用的jdkSerializeable, 存储二进制字节码, 所以自定义序列化类
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 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.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
