java中使用正则表达式
使用apache的oro包
//匹配 'abc@jcc.inn' 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 = " 'abc@jcc.inn' 2011/06/03 9:50";
if (matcher.contains(line, pattern)) {
MatchResult result = matcher.getMatch();
String findStr = result.group(0);
}
