把这个shipNotWorkSpacesMap全部拿出来entries

// 从 Redis 中获取 shipNotWorkSpacesMap
Map<String, List<Point2D.Double>> redisMap = (Map<String, List<Point2D.Double>>) redisTemplate.boundHashOps("shipNotWorkSpacesMap").entries();

// 输出获取的 map
System.out.println(redisMap);

取某一个key对应的值
 

List<Point2D.Double>  dhShipSpacesList = (List<Point2D.Double>) redisTemplate.boundHashOps("h34PointMap").get("23340");
