优化代码： private static MapString Object parseJSON2MapString jsonStr MapString Object map = new HashMapString Object; 最外层解析 JSONObject json = JSONObjectfromObjectjsonStr

改进后的代码：

private static Map<String, Object> parseJSON2Map(String jsonStr) { Map<String, Object> map = new HashMap<>();

JSONObject json = JSONObject.fromObject(jsonStr);
for (String key : json.keySet()) {
    Object value = json.get(key);
    if (value instanceof JSONArray) {
        List<Map<String, Object>> list = new ArrayList<>();
        for (Object obj : (JSONArray) value) {
            list.add(parseJSON2Map(obj.toString()));
        }
        map.put(key, list);
    } else if (value instanceof JSONObject) {
        map.put(key, parseJSON2Map(value.toString()));
    } else {
        map.put(key, value);
    }
}
return map;

}
