-Java 存儲與python共享數據時，應避免將String字符串當做對象進行序列化存儲，應直接以字符串的形式存 儲，如果需要共享對象，對象轉化為json串存儲。 @SuppressWarnings("resource")public static Map<String,String> getAllHashByKey(String key) {try {JedisPool pool = null;pool = new JedisPool(RedisUtil.REDIS_HOST,RedisUtil.REDIS_PORT);Jedis jedisClient = pool.getResource();jedisClient.auth(RedisUtil.REDIS_PASSWORD);Map<String, String> map = jedisClient.hgetAll(key);return map;} catch (Exception e) {e.printStackTrace();return null;}}
