snmp4j初学代码

代码说明：

简单的连接snmp agent 然后get数据 在main函数中 Address targetAddress=GenericAddress.parse("udp:192.168.5.151/161");   TransportMapping transport=new DefaultUdpTransportMapping();   Snmp snmp=new Snmp(transport);   transport.listen();   CommunityTarget target=new CommunityTarget();   target.setCommunity(new OctetString("WinSpread"));   target.setAddress(targetAddress);   target.setRetries(3);   target.setTimeout(5000);   target.setVersion(1);   PDU request=new PDU();   request.setType(PDU.SET); //  request.add(new VariableBinding(new OID("IP-FORWARD-MIB::inetCidrRouteMetric4.ipv4"))); //  request.add(new VariableBinding(new OID("IP-MIB::ipAdEntAddr"))); //  request.add(new VariableBinding(new OID(".1.3.6.1.2.1.1.3.0"))); //
