Java -从JsonObject中删除匹配正则表达式的键

JsonObject jsonObject = new JsonObject();
// 假设jsonObject是已经存在的JsonObject对象

// 将JsonObject转换为Map对象
Map<String, Object> map = new Gson().fromJson(jsonObject.toString(), new TypeToken<Map<String, Object>>() {}.getType());

String regex = "your_regex_pattern";
Pattern pattern = Pattern.compile(regex);

Iterator<Map.Entry<String, Object>> iterator = map.entrySet().iterator();
while (iterator.hasNext()) {
    Map.Entry<String, Object> entry = iterator.next();
    String key = entry.getKey();

    // 使用正则表达式匹配键
    Matcher matcher = pattern.matcher(key);
    if (matcher.find()) {
        iterator.remove(); // 删除匹配的键
    }
}

JsonObject updatedJsonObject = new Gson().toJsonTree(map).getAsJsonObject();
