String input = " Fa0/1     --- Cisco IP phone notconnected   20       a-full    auto    10/100BaseTX"
String DISABLED = "disabled";
String CONNECTED = "connected";
String NOTCONNECTED = "notconnected";    
String REGEXP_STATUS = "^(\\s*)(\\w+/\\d+|\\w+/\\d+/\\d+)(\\s+)(.*|\\*|-)(" + NOTCONNECTED + "|" + DISABLED + "|" + CONNECTED + ")(\\s+)(\\d+|trunk)(\\s+)(\\w+|a-\\w+)(\\s+)(\\w+|a-\\d+)(\\s+)(\\w+|/+).*";

matcher.group(5) 返回 CONNECTED 如果输入是 NOTCONNECTED 因为 有联系的 消息不在 有联系的

编辑:

我尝试:

String REGEXP_STATUS = "^(\\s*)(\\w+/\\d+|\\w+/\\d+/\\d+)(\\s+)(.*|\\*|-)(" + DISABLED + "|.*" + CONNECTED + ")(\\s+)(\\d+|trunk)(\\s+)(\\w+|a-\\w+)(\\s+)(\\w+|a-\\d+)(\\s+)(\\w+|/+).*";

返回和 matcher.group(4) 返回 --- Cisco IP phone not

将其更改为使用惰性量词 .*?
但是,这些交替部分(*? | \* | - ) 永远不会被触动。
