JAVA 获取 Tomcat 端口

public class RunTimeUtil {
	
	//获取 tomcat 运行端口
	public static int getTomcatPort(){
    	
    	int port = 0 ;

	MBeanServer mBeanServer = null;
	ArrayList mBeanServers = MBeanServerFactory.findMBeanServer(null);
	if (mBeanServers.size() > 0) {
	
	mBeanServer = mBeanServers.get(0);
	
	}

	if (mBeanServer == null) {
		throw new IllegalStateException("没有发现JVM中关联的MBeanServer.");
	}
	
	Set objectNames = null;
	try {
		objectNames = mBeanServer.queryNames(new ObjectName("Catalina:type=Connector,*"), null);
	} 
	catch (MalformedObjectNameException e) {
		e.printStackTrace();
	} 
	catch (NullPointerException e) {
		e.printStackTrace();
	}
	
	if (objectNames == null || objectNames.size() <= 0) {
		throw new IllegalStateException("没有发现JVM中关联的MBeanServer : "+ mBeanServer.getDefaultDomain() + " 中的对象名称.");
	}
	
	try {
		for (ObjectName objectName : objectNames) {
			String protocol = (String) mBeanServer.getAttribute(objectName, "protocol");
			if (protocol.equals("HTTP/1.1")) {
			port = (Integer) mBeanServer.getAttribute(objectName, "port");
		}
	}
	} catch (AttributeNotFoundException e) {
		e.printStackTrace();
	} catch (InstanceNotFoundException e) {
		e.printStackTrace();
	} catch (MBeanException e) {
		e.printStackTrace();
	} catch (ReflectionException e) {
		e.printStackTrace();
	}
	
	return port;

    }
	

}

调用：

String tomcatPort = String.valueOf(RunTimeUtil.getTomcatPort());
