Matcher在匹配后抛出IllegalStateException
我对Matches有一些奇怪的问题，希望有人可以解决一些问题。
根据Java文档：
public boolean matches（）...如果是
匹配成功然后更多信息
可以通过开始，结束，
和小组方法。
一些代码：
private static Hashtable<String,String> splitAddress(String address){
Hashtable<String,String> result = new Hashtable<String,String>();
Matcher m = addrLong.matcher(address);
if (m.matches()) {
result.put("number", m.group(1));
java.lang.IllegalStateException: No match found
java.util.regex.Matcher.group(Matcher.java:485)
splitAddress(WebServiceHelper.java:699)
private static final String numberRegex = "[0-9]*[a-zA-Z]?"; // 123a 123
private static final String compassRegex = "N|E|S|W|NORTH|EAST|SOUTH|WEST|NORD|EST|SUD|OUEST";
private static final String typeRegex = "STREET|ST|DRIVE|DR|AVENUE|AVE|AV|ROAD|RD|LOOP|LP|COURT|CT|CIRCLE|LANE|LN|BOULEVARD|BLVD|CRESCENT|CR";
addrLong = Pattern.compile("(" + numberRegex + ")\s(.*)\s(" + typeRegex + ")\s?(" + compassRegex + ")?");
Pattern p = Pattern.compile("(" + numberRegex + ")\s(.*)");
Matcher m = p.matcher(address);
if (m.matches()) {
result.put("number", m.group(1));
没有找到相关结果
