@Configuration
    public class RedisConfig { 
    
        @Bean
        @SuppressWarnings("all")
        public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory)
                throws UnknownHostException { 
            RedisTemplate<String, Object> template = new RedisTemplate<>();
            template.setConnectionFactory(factory);
            // Json序列化配置
            Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
            ObjectMapper om = new ObjectMapper();
            // 指定要序列化的域，field,get和set,以及修饰符范围，ANY是都有,包括private和public
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            // 指定序列化输入的类型，类必须是非final修饰的，final修饰的类，比如String,Integer等会抛出异常
            //om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); //@Deprecated 已过时
            om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
            jackson2JsonRedisSerializer.setObjectMapper(om);
    
            //配置具体的序列化方式
            StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
    
            //key采用String的序列化方式
            template.setKeySerializer(stringRedisSerializer);
    
            //hash的key也采用String的序列化方式
            template.setHashKeySerializer(stringRedisSerializer);
    
            //value序列化采用jackson
            template.setValueSerializer(jackson2JsonRedisSerializer);
            template.setHashValueSerializer(jackson2JsonRedisSerializer);
            template.afterPropertiesSet();
    
            return template;
        }
    }
