MINA与JMX集成（翻译）

JMX（Java Management Extensions）用来管理和监视java应用程序。

增加JMX支持

为使MINA应用程序支持JMX，需要做以下工作：

创建/获取MBean服务器

// create a JMX MBean Server server instanceMBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer(); 

实例化要求的MBeans（IoAcceptor, IoFilter）

// create a JMX-aware bean that wraps a MINA IoService object. In this case, a NioSocketAcceptor. 
IoServiceMBean acceptorMBean = new IoServiceMBean( acceptor );

在MBean服务器上注册MBeans

// create a JMX ObjectName. This has to be in a specific format.
 ObjectName acceptorName = new ObjectName( acceptor.getClass().getPackage().getName() + ":type=acceptor,name=" 
+ acceptor.getClass().getSimpleName()); 
// register the bean on the MBeanServer. Without this line, no JMX will happen for this acceptor. 
mBeanServer.registerMBean( acceptorMBean, acceptorName );

启动Imagine Server

org.apache.mina.example.imagine.step3.server.ImageServer

开启Jconsole

开启Jconsole使用如下命令：

/bin/jconsole

We can see the different attributes and operations that are exposed by the MBeans
