import java.io.IOException; import java.net.InetAddress; import org.snmp4j.CommunityTarget; import org.snmp4j.PDU; import org.snmp4j.Snmp; import org.snmp4j.event.ResponseEvent; import org.snmp4j.mp.SnmpConstants; import org.snmp4j.smi.OID; import org.snmp4j.smi.OctetString; import org.snmp4j.smi.UdpAddress; import org.snmp4j.smi.VariableBinding; import org.snmp4j.transport.DefaultUdpTransportMapping; public class TestOp { public static void main(String[] args) { try { Snmp snmp = new Snmp(new DefaultUdpTransportMapping()); CommunityTarget target = new CommunityTarget();//agent对象 target.setCommunity(new OctetString("public"));//设置共同体名,没发现设置RWCommnity的方法,大概只能设一个. target.setVersion(SnmpConstants.version2c);//设置版本 target.setAddress(new UdpAddress("127.0.0.1/161"));//设置IP地址和端口号,这里竟然用'/'来分 //隔,当初确实没有料到,JDOC的说明等于没有. target.setRetries(1); //设置重试次数 target.setTimeout(5000); //设置超时 snmp.listen(); //监听 PDU request = new PDU(); //new request PDU包 //set pud type and set oid request.setType(PDU.GET); //设置PDU类型 request.add(new VariableBinding(new OID(".1.3.6.1.2.1.1.1.0"))); //OID添加 request.add(new VariableBinding(new OID(".1.3.6.1.2.1.1.2.0"))); System.out.println("request UDP:" + request);//请求包内内容输出, PDU response = null;//定义response包 ResponseEvent responseEvent = snmp.send(request, target); //发出request PDU //接收response PDU response = responseEvent.getResponse(); //response PDU包解析 if(response!=null){ if(response.getErrorIndex()==response.noError&&response.getErrorStatus()==response.noError){ System.out.println("no error."); String pause=responseEvent.getResponse().getVariableBindings().toString(); String getvalue=pause.substring( pause.indexOf("= ")+2,pause.indexOf(']')); String oid=pause.substring(pause.indexOf("VBS[")+2,pause.indexOf("=")-1); System.out.println(oid+"::"); System.out.println(response); }else{ System.out.println("get error:"+response.getErrorStatusText()); } }else{ System.out.println("get response error"); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

执行结果:
request UDP:GET[requestID=0, errorStatus=Success(0), errorIndex=0, VBS[1.3.6.1.2.1.1.1.0 = Null; 1.3.6.1.2.1.1.2.0 = Null]]
no error.
1.3.6.1.2.1.1.1.0::
RESPONSE[requestID=18464556, errorStatus=Success(0), errorIndex=0, VBS[1.3.6.1.2.1.1.1.0 = Hardware: x86 Family 6 Model 14 Stepping 8 AT/AT COMPATIBLE - Software: Windows 2000 Version 5.1 (Build 2600 Uniprocessor Free); 1.3.6.1.2.1.1.2.0 = 1.3.6.1.4.1.311.1.1.3.1.1]]

这里response.getVariableBindings()返回的是VaribleBinding数组,应该根据名个VaribleBinding对象解析得到OID值.所以上面的程序稍微有点问题.

上面的程序是一个GET的操作,GETNEXT,SET,GETBULK的操作也相似,
在snmp4j Jdoc中,

org.snmp4j.Snmp下面有较为详细的例子可以参考.
