java日常-com.alibaba.fastjson快速处理json字符串转成list类型

public static List<Map<String, String>> jsonToList(String json) {
        JSONReader reader = new JSONReader(new StringReader(json));// 已流的方式处理，这里很快
        reader.startArray();
        List<Map<String, String>> rsList = new ArrayList<Map<String, String>>();
        Map<String, String> map = null;
        int i = 0;
        while (reader.hasNext()) {
            i++;
            reader.startObject();// 这边反序列化也是极速
            map = new HashMap<String, String>();
            while (reader.hasNext()) {
                String arrayListItemKey = reader.readString();
                String arrayListItemValue = reader.readObject().toString();
                map.put(arrayListItemKey, arrayListItemValue);
            }
            rsList.add(map);
            reader.endObject();
        }
        reader.endArray();
        return rsList;
    }
