正则常见用法(例子来源：hutool文档)：
String content = "ZZZaaabbbccc中文1234";
Pattern pattern = Pattern.compile(regex, Pattern.DOTALL);
Matcher matcher = pattern.matcher(content);
if (matcher.find()) {
String result= matcher.group();
}
hutool中的写法：
String content = "ZZZaaabbbccc中文1234";
boolean isMatch = ReUtil.isMatch("\w+[\u4E00-\u9FFF]+\d+", content);
Assert.assertTrue(isMatch);
