查询字符串中是否包含某个字符

例如：查询字符串中是否包含i18n{}字样

public static final String I18N_REGEX = "i18n\{(.+?)\}";

/**
 * @param message
 * @throws
 * @description 查询字符串中是否包含i18n字样
 * @createTime 2023-12-07 22:22:45
 */

        return false;
    }

    Matcher matcher = pattern.matcher(message);
    return matcher.matches();
