java 正则表达式问题

网址为:

https://gongshang.mingluji.com/beijing/name/北京聚源润鼎文化有限公司

ResponseComs 是请求这个网址返回的内容string
下面的代码:

String PostPatter="<span class='field-label'>[u4e00-u9fa5].*?(d+)</span></span>";
Pattern r = Pattern.compile(PostPatter);
Matcher m = r.matcher(ResponseComs);
System.out.println("邮政编码:");
System.out.println(String.valueOf(m));**

打印情况为:
java.util.regex.Matcher[pattern=<span class='field-label'>[u4e00-u9fa5].*?(d+)</span></span> region=0,46452 lastmatch=]
