java中使用正则表达式

使用apache的oro包
//匹配  '[e-mail]'  2011/06/03 9:50

        String regrex = "'[a-z]([a-z0-9]*[-_]?[a-z0-9]+)*@([a-z0-9]*[-_]?[a-z0-9]+)+[\\.][a-z]{2,3}([\\.][a-z]{2})?'\\s+\\d{4}/\\d{2}/\\d{2}\\s+\\d{1,2}:\\d{2}";

        compiler = new Perl5Compiler();
        pattern = null;
        try {
            pattern = compiler.compile(regrex);
        } catch (MalformedPatternException e) {
            logger.error(e);
            return;
        }
        matcher = new Perl5Matcher();
        String line = "       '[e-mail]'  2011/06/03 9:50";
        if (matcher.contains(line, pattern)) {
            MatchResult result = matcher.getMatch();
            String findStr = result.group(0);
        }
