你可以试试regexstringcomparator

RegexStringComparator regexStringComparator = new RegexStringComparator("^[aA][bB][cC]$");//will match aBc or ABC or Abc any case in order of a followed by b followed by c.
SingleColumnValueFilter filter = new SingleColumnValueFilter(
    cf,
    column,
    CompareOp.EQUAL,
    regexStringComparator
    );
scan.setFilter(filter);
