Tomcat启动时获取访问地址和端口号

遇到一个单节点多实例部署的情况，且配置文件部署平台统一管理了，在这种情况下想到用端口号区分具体实例。搜了一圈发现都是一个版本且存在问题的源码，干脆自己搞了一个。废话不说了，直接上源码。

    List<String> getEndPoints() throws MalformedObjectNameException,
            NullPointerException, UnknownHostException, AttributeNotFoundException,
            InstanceNotFoundException, MBeanException, ReflectionException {
        MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
        Set<ObjectName> objs = mbs.queryNames(new ObjectName("*:type=Connector,*"),
                Query.match(Query.attr("protocol"), Query.value("HTTP/1.1")));
        String hostname = InetAddress.getLocalHost().getHostName();
        InetAddress[] addresses = InetAddress.getAllByName(hostname);
        ArrayList<String> endPoints = Lists.newArrayList();
        for (Iterator<ObjectName> i = objs.iterator(); i.hasNext(); ) {
            ObjectName obj = i.next();
            String scheme = mbs.getAttribute(obj, "scheme").toString();
            String port = obj.getKeyProperty("port");
            for (InetAddress addr : addresses) {
                String host = addr.getHostAddress();
                String ep = scheme + "://" + host + ":" + port;
                endPoints.add(ep);
            }
        }
        return endPoints;
    }
