code: public static FieldMatcher make(String actived, String locked, boolean ignoreNull) {
          FieldMatcher fm = new FieldMatcher();
          fm.ignoreNull = ignoreNull;
          if (!Strings.isBlank(actived))
              fm.actived = Regex.getPattern(actived);
          if (!Strings.isBlank(locked))
              fm.locked = Regex.getPattern(locked);
          return fm;
      }

  @param actived 需要保留的字段,必须是合法的正则表达式,可以为null
  @param locked  需要忽略的字段,必须是合法的正则表达式,可以为null
