》》分析下面的数字对，中间用逗号隔开：
asf123，343asdf af1234 ，555asdf as5556， 88fsda 666 , 9999 dfd666ff,ffff9999fdd dfd666 ,ffff9999fdd
代码：
String dataText = "asf123，343asdf/r/n af1234 ，555asdf/r/n s5556， 88fsda/r/n 666 , 9999/r/n dfd666ff,ffff9999fdd/r/n dfd666 ,ffff9999fdd";
Pattern p = Pattern.compile("(\\d+)[ \t]*,[ \t]*(\\d+)");
Matcher m = p.matcher(dataText);
while (m.find()) {
System.out.println(StringUtil.toInt(m.group(1)) + "," + StringUtil.toInt(m.group(2)));
}
结果：
666,9999
>>替换Java代码中的aaa.toString()到StrUtil.toStr(aaa)
dayVo = new DayVo(dSales.toString(), dGm.toString(), dNgm .toString(), dOplgm.toString(), dTgm.toString()); wTDVo = new WTDVo(wSales.toString(), wGm.toString(), wNgm .toString(), wOplgm.toString(), wTgm.toString()); mTDVo = new MTDVo(mSales.toString(), aveMSales.toString(), mGm .toString(), mNgm.toString(), mOplgm.toString(), mTgm .toString());
查找aaa.toString()正则表达式
(\w+)\s*.toString\(
替换StrUtil.toStr(aaa)正则表达式
StrUtil.toStr\(\1
这里通过\1拿第一个捕获组，如果有多个，则使用\2,\3.....来取。
替换后的代码：
dayVo = new DayVo(StrUtil.toStr(dSales), StrUtil.toStr(dGm), StrUtil.toStr(dNgm), StrUtil.toStr(dOplgm), StrUtil.toStr(dTgm));
wTDVo = new WTDVo(StrUtil.toStr(wSales), StrUtil.toStr(wGm), StrUtil.toStr(wNgm), StrUtil.toStr(wOplgm), StrUtil.toStr(wTgm));
mTDVo = new MTDVo(StrUtil.toStr(mSales), StrUtil.toStr(aveMSales), StrUtil.toStr(mGm), StrUtil.toStr(mNgm), StrUtil.toStr(mOplgm), StrUtil.toStr(mTgm));
