请教正则表达式的问题

[digisdio]

如下所示的JDBC URL：
jdbc:sqlserver://haha.com:1433;DataBaSeNAME=xyz;a=b;b=3;c=2;

用如下的RegEx匹配后，仅能找到4个group，分别是“haha.com”、“1433”、“xyz”和“c=2”，不知为何“a=b”和“b=3”无法捕获，重点是红字粗体那部分，请高人赐教：

^jdbc:sqlserver://((?:(?:(?:(?:[\w&&[^_]])+(?:[\w|-])*(?:[\w]?[.]))*)(?:(?:[A-Z|a-z])+(?:[\w|-])*(?:[\w]?)))|(?:(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))|(?:(?:(?:(?:[0-9A-Fa-f]{1,4}:){7}(?:[0-9A-Fa-f]{1,4}|:))|(?:(?:[0-9A-Fa-f]{1,4}:){6}(?::[0-9A-Fa-f]{1,4}|(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(?:(?:[0-9A-Fa-f]{1,4}:){5}(?:(?:(?::[0-9A-Fa-f]{1,4}){1,2})|:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(?:(?:[0-9A-Fa-f]{1,4}:){4}(?:(?:(?::[0-9A-Fa-f]{1,4}){1,3})|(?:(?::[0-9A-Fa-f]{1,4})?:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(?:(?:[0-9A-Fa-f]{1,4}:){3}(?:(?:(?::[0-9A-Fa-f]{1,4}){1,4})|(?:(?::[0-9A-Fa-f]{1,4}){0,2}:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(?:(?:[0-9A-Fa-f]{1,4}:){2}(?:(?:(?::[0-9A-Fa-f]{1,4}){1,5})|(?:(?::[0-9A-Fa-f]{1,4}){0,3}:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(?:(?:[0-9A-Fa-f]{1,4}:){1}(?:(?:(?::[0-9A-Fa-f]{1,4}){1,6})|(?:(?::[0-9A-Fa-f]{1,4}){0,4}:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(?::(?:(?:(?::[0-9A-Fa-f]{1,4}){1,7})|(?:(?::[0-9A-Fa-f]{1,4}){0,5}:(?:(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:)))(?:%.+)?)):([0-9]{1,5});([a-zA-Z]\w*=\w+;)*(?i:DatabaseName)=([a-zA-Z]\w*);*(?:([a-zA-Z]\w*=\w+);)*([a-zA-Z]\w*=\w+)?;*$

lz你这是啥啊，看的我头大，你就说你想干啥吧。

[hahawaa1]

LZ 我绝对你应该重新输入一边 这种问题我碰到过 重新输入边就好了

[digisdio]

红字粗体部分剪短改成这样也是同样的结果：
([a-zA-Z]\w*=\w+;)*(?i:DatabaseName)=([a-zA-Z]\w*);*(?:([a-zA-Z]\w*=\w+);*)*$

[digisdio]

我就想提取host、port和dbname和其他的属性

[digisdio]

前面那一大堆不用细看，是匹配是否ipv4或者ipv6或者主机名的，都删掉都行，而且那是久经考验的，就是port之后取db属性这部分达不到效果。

[softroad]

不知道这个可以不

     String url = "jdbc:sqlserver://haha.com:1433;DataBaSeNAME=xyz;a=b;b=3;c=2;";
     Pattern p = Pattern.compile("[\\w\\d\\:.=]+;");
     Matcher m = p.matcher(url);


     while(m.find()) {
        System.err.println(m.group());
     }

     String[] s = url.split(";");
     System.err.println(java.util.Arrays.toString(s));

[softroad]

其实用；分割最简单了。
