如何保持SNMP代理的活动状态

Question

我使用snmp4j库成功创建了SNMP代理，这是引用代码。

我的问题是如何让这个代理始终运行以监听来自经理的所有传入OID。？？

public synchronized void listen() throws IOException
      {
         TransportIpAddress address2=  new UdpAddress(2069);
        AbstractTransportMapping transport;
        if (address2 instanceof TcpAddress)
        {
          transport = new DefaultTcpTransportMapping((TcpAddress) address2);
        }
        else
        {
         //  transport = new DefaultUdpTransportMapping( (UdpAddress) address2);
               transport = new DefaultUdpTransportMapping();
        }

        ThreadPool threadPool = ThreadPool.create("DispatcherPool", 10);
        MessageDispatcher mtDispatcher = new MultiThreadedMessageDispatcher(threadPool, new MessageDispatcherImpl());

        // add message processing models
        mtDispatcher.addMessageProcessingModel(new MPv1());
        mtDispatcher.addMessageProcessingModel(new MPv2c());

        // add all security protocols
        SecurityProtocols.getInstance().addDefaultProtocols();
        SecurityProtocols.getInstance().addPrivacyProtocol(new Priv3DES());

        //Create Target
        CommunityTarget target = new CommunityTarget();
        target.setCommunity( new OctetString("password"));

        Snmp snmp = new Snmp(mtDispatcher, transport);
        snmp.addCommandResponder(this);

        transport.listen();
        System.out.println("Listening on " + address);

        try
        {
          this.wait();
        }
        catch (InterruptedException ex)
        {
          Thread.currentThread().interrupt();
        }
      }
