如何在Java EE中以编程方式获取绑定的服务器地址和端口？ [英] How to get bound server address and port programmatically in Java EE?

问题描述

在启动时，我们需要获取正在运行的应用程序的服务器地址和http端口。到目前为止，我们这样做：

At startup we need to get the server address and the http port of the running application. Until now we made it like this:

MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
ObjectName socketBindingMBean = new ObjectName("jboss.as:socket-binding-group=standard-sockets,socket-binding=http");

String  host = (String)  mBeanServer.getAttribute(socketBindingMBean, "boundAddress"),
Integer port = (Integer) mBeanServer.getAttribute(socketBindingMBean, "boundPort"));

一切都很好但是从jBoss 7.1.1.Final迁移到7.1.3.Final我们得到了在服务器启动时未定义MBean的问题。这意味着如果我在已经运行的 jboss服务器上部署应用程序，一切都很好，但是如果我启动服务器并且在服务器启动期间加载了应用程序MBean不在那里。

Everything was fine but after migration from jBoss 7.1.1.Final to 7.1.3.Final we got the problem that the MBean isn't defined at server startup. That means everything is fine if I deploy the application on an already running jboss server, but if I start the server and the application is loaded up during server start MBeans are not there.

我不知道为什么，但我感觉jBoss确保在大多数MBean之前启动/加载应用程序。我看了一眼，发现我们申请后加载了Mbeans：

I don't know why but I have the feeling that jBoss makes sure, that out application is started/loaded before most of the MBeans. I had a small look and found out that following Mbeans are loaded after our application:

• jboss.as:interface = ..


• jboss.as:socket-binding-group = ..


• jboss.as:subsystem = ..


• jboss.as:core-service=management ..（some）

• jboss.as:interface=..
• jboss.as:socket-binding-group=..
• jboss.as:subsystem=..
• jboss.as:core-service=management.. (some)

所以，

• 如何在我的应用程序之前强制jBoss加载MBean？


• 还有另一种方式/ mbean我可以获取我的信息吗？

推荐答案

我在JBOSS Wildfly 8.1中遇到了同样的问题。我用下面的代码解决了这个问题，这个代码对我有用，可以获得服务器地址和http端口：

I got the same issue in JBOSS Wildfly 8.1 . I solved the problem with the code below that worked for me to get server address and http port:

//http port
ManagementFactory.getPlatformMBeanServer().getAttribute(new ObjectName("jboss.as:socket-binding-group=standard-sockets,socket-binding=http"), "port");

//http adress
ManagementFactory.getPlatformMBeanServer().getAttribute(new ObjectName("jboss.as:interface=public"), "inet-address");
