java - 如何确定MINA中的服务器端口

在我的应用程序中，我有一台监听多个udp端口的服务器。我在此应用程序中使用了MINA。

// code looks like this.
NioDatagramAcceptor acceptor = new NioDatagramAcceptor();
...
...
acceptor.bind(new InetSocketAddress(9911));
acceptor.bind(new InetSocketAddress(9912));

现在在处理程序中，当我收到数据时，我有以下代码。

@Override
public void messageReceived(IoSession session, Object message)
        throws Exception {
    if (message instanceof IoBuffer) {
        String msg = "data received in port "+ <NEED TO GET THE PORT NO>;
        System.out.println(msg);
    }
}

在代码中，我不知道如何获取接收数据的端口号（在这种情况下为9911或9912）。

提前致谢。

最佳答案

参考：http://mina.apache.org/report/trunk/apidocs/org/apache/mina/core/session/IoSession.html

@Override
public void messageReceived(IoSession session, Object message)
    throws Exception {
if (message instanceof IoBuffer) {
    InetSocketAddress inetSocketAddress = (InetSocketAddress) session.getServiceAddress();
    int portNumber = inetSocketAddress.getPortNumber();
    String msg = "data received in port "+ portNumber;
    System.out.println(msg);
}
