GroupBy 和 Stream Filter 基于每个日期 java 列表中特定记录的最大字段

我有一个list分，看起来像下面这样

[
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-27 05:22:46",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 1,
    "currentSpeed": 67,
    "passengersNo": 80
  },
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-27 07:12:10",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 2,
    "currentSpeed": 56,
    "passengersNo": 11
  },
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-26 03:12:10",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 3,
    "currentSpeed": 31,
    "passengersNo": 15
  },
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-26 03:12:10",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 3,
    "currentSpeed": 78,
    "passengersNo": 15
  },
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-26 04:34:10",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 7,
    "currentSpeed": 49,
    "passengersNo": 57
  }
]

我想要实现的是过滤，例如，分别在日期2022-08-27和日期2022-08-26，我只返回一个最大值为currentSpeed的记录，这样我的最终列表如下所示

[
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-27 05:22:46",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 1,
    "currentSpeed": 67,
    "passengersNo": 80
  },
  {
    "busId": "4-3323309834",
    "dataDateTime": "2022-08-26 03:12:10",
    "busName": "27Tr Solaris Single Deck",
    "speedLimit": 80,
    "id": 3,
    "currentSpeed": 78,
    "passengersNo": 15
  }
]

下面是我的代码外观以及我填充列表的方式

public static void main(String[] args) {

        List<HashMap<String, Object>> myList = new ArrayList<>();

        myList.add(new HashMap<>(Map.of("id", 1,
                "busId","4-3323309834",
                "busName","27Tr Solaris Single Deck",
                "currentSpeed",67,
                "passengersNo",80,
                "speedLimit",80,
                "dataDateTime","2022-08-27 05:22:46")));

        myList.add(new HashMap<>(Map.of("id",2,
                "busId","4-3323309834",
                "busName","27Tr Solaris Single Deck",
                "currentSpeed",56,
                "passengersNo",11,
                "speedLimit",80,
                "dataDateTime","2022-08-27 07:12:10")));

        myList.add(new HashMap<>(Map.of(
                "id",3,
                "busId","4-3323309834",
                "busName","27Tr Solaris Single Deck",
                "currentSpeed",31,
                "passengersNo",15,
                "speedLimit",80,
                "dataDateTime","2022-08-26 03:12:10")));

        myList.add(new HashMap<>(Map.of(
                "id",3,
                "busId","4-3323309834",
                "busName","27Tr Solaris Single Deck",
                "currentSpeed",78,
                "passengersNo",15,
                "speedLimit",80,
                "dataDateTime","2022-08-26 03:12:10")));

        myList.add(new HashMap<>(Map.of(
                "id",7,
                "busId","4-3323309834",
                "busName","27Tr Solaris Single Deck",
                "currentSpeed",49,
                "passengersNo",57,
                "speedLimit",80,
                "dataDateTime","2022-08-26 04:34:10")));

    }

下面是我试图使用的过滤器，但我在下面的过滤器代码中得到了Not a statement

        List<HashMap<String, Object>> myList2 = myList.stream()
                .collect(Collectors.groupingBy(hashmap ->
                                List.of(hashmap.get("busId"),
                                        hashmap.get("currentSpeed"),
                        Collectors.maxBy(Comparator.comparing(HashMap::get("dataDateTime")))));




        System.out.println(Config.ANSI_CYAN + "MyListToJsonPrint: " +
                new GsonBuilder().setPrettyPrinting().create().toJson(myList2));

有没有一种有效的方法可以用来过滤
