如果创建域的开始阶段没有为AdminServer指定绑定地址,那么weblogic遍历所在主机的所有IP地址。每一个IP地址创建一个ServerSocket,也就是我们在界面上看到channel,比如以下输出:

<2012-8-13 下午06时32分39秒 CST> listening on channe
l "Default[4]". The address fe80:0:0:0:0:0:0:1 might be incorrect or another process is using port 7001: java.net.BindEx
ception: Cannot assign requested address: JVM_Bind.>

<2012-8-13 下午06时32分39秒 CST> <Channel "Default[6]" is now listening on 127.0.0.1:7001

<2012-8-13 下午06时32分39秒 CST> <Channel "Default" is now listening on 192.168.1.62:7001
 for protocols iiop, t3, ldap, snmp, http.>
<2012-8-13 下午06时32分39秒 CST>  domain "base_domain" running in Development Mode>

从上面的输出可以看到,总共有7个channel,有的绑定成功,有的失败:

1. fe80:0:0:0:0:0:0:1 :                    Default[4]

2. fe80:0:0:0:224:1dff:fe2a:689a  Default[3]

3. fe80:0:0:0:0:ffff:ffff:fffd            Default[2]

4. fe80:0:0:0:0:5efe:c0a8:13e        Default[1]

5. 192.168.1.62                            Default/Default[0]

6. 127.0.0.1                                  Default[6]

7. 0:0:0:0:0:0:0:1                           Default[5]

我们罗列一下机器的IP地址:

public static void main(String[] args) throws IOException {
        Enumeration eni = NetworkInterface.getNetworkInterfaces();
        while(eni.hasMoreElements()){
            NetworkInterface ni = eni.nextElement();
            Enumeration eIa = ni.getInetAddresses();
            while(eIa.hasMoreElements()){
                System.out.println(eIa.nextElement().getHostName());
            }
        }
    }

127.0.0.1
