对于json数组，将List<Object>转换为List<HashMap<String、Double>>

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonArrayConverter {
    public static List<HashMap<String, Double>> convert(List<Object> list) {
        List<HashMap<String, Double>> result = new ArrayList<>();

        ObjectMapper objectMapper = new ObjectMapper();

        for (Object obj : list) {
            String json = objectMapper.writeValueAsString(obj);
            Map<String, Object> map = objectMapper.readValue(json, new TypeReference<Map<String, Object>>() {});

            HashMap<String, Double> hashMap = new HashMap<>();

            for (Map.Entry<String, Object> entry : map.entrySet()) {
                String key = entry.getKey();
                Double value = Double.parseDouble(entry.getValue().toString());
                hashMap.put(key, value);
            }

            result.add(hashMap);
        }

        return result;
    }
}
