java - Redis Hash结构存储Long取出为Integer原因及解决方案？

Question

Redis库使用的是spring-boot-data-redis,Redis的Hash结构存储Long数字类型，但取出来的是Integer，不用Hash直接存，取的就是Long，这是为什么？有办法Hash取的也是Long吗

直接存：

存到hash中：

存储hash的代码：

    private void setArticleActiveHash(Long articleId) {        String key = "article_active:"+ articleId;        Map<String, Long> articleActiveMap = new HashMap<>();        articleActiveMap.put("love", 0L);        articleActiveMap.put("commentCount", 0L);        articleActiveMap.put("watch", 0L);        articleActiveMap.put("collectionCount", 0L);        articleActiveMap.put("articleId",articleId);        redisCache.setCacheMap(key,articleActiveMap);    }

RedisConfig

@Configurationpublic class RedisConfig {    @Resource(type = RedisConnectionFactory.class)    private RedisConnectionFactory redisConnectionFactory;    @Primary    @Bean    public RedisTemplate<String, Object> redisTemplate() {        RedisTemplate<String, Object> template = new RedisTemplate<>();        template.setConnectionFactory(redisConnectionFactory);        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);        ObjectMapper objectMapper = new ObjectMapper();        // 解决反序列化 LocalDateTime 的错误        objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);        // 解决 LocalDateTime 序列化失败的问题        objectMapper.registerModule(new JavaTimeModule());        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);        objectMapper.activateDefaultTyping(                LaissezFaireSubTypeValidator.instance,                ObjectMapper.DefaultTyping.NON_FINAL,                JsonTypeInfo.As.WRAPPER_ARRAY);        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();        // key 采用 String 的序列化方式        template.setKeySerializer(stringRedisSerializer);        // value 序列化方式采用 jackson        template.setValueSerializer(jackson2JsonRedisSerializer);        // hash 的 key 也采用 String 的序列化方式        template.setHashKeySerializer(stringRedisSerializer);        // hash 的 value 序列化方式采用 jackson        template.setHashValueSerializer(jackson2JsonRedisSerializer);        template.afterPropertiesSet();        return template;    }}

虽然可以拿到后转Long，但每次都转好麻烦

序列化器的问题，配置类改为的序列化器改为GenericFastJsonRedisSerializer就好了
