Springboot中redisTemplate亂碼或json轉換問題

問題1

用RedisTemplate存入map值的時候，用rdm可視化打開，看到的是轉碼之后的數據，如圖：

存入的方法為：

public boolean hmset(String key, Map<String, Object> map) {
    try {
        redisTemplate.opsForHash().putAll(key, map);
        return true;
    } catch (Exception e) {
        log.error(key, e);
        return false;
    }
}

問題2

存入的json字符串取出來后不能轉換錯誤

解決辦法

@Resource
private RedisConnectionFactory redisConnectionFactory;

@Bean
public RedisTemplate redisTemplate() {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    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);
    // 防止亂碼
    RedisSerializer stringSerializer = new StringRedisSerializer();
    redisTemplate.setKeySerializer(stringSerializer);
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer); //解決json轉換
    redisTemplate.setHashKeySerializer(stringSerializer);
    redisTemplate.setHashValueSerializer(stringSerializer);//解決哈唏值轉換
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}
