如何从 Java 应用程序发送 snmpv2 陷阱。我试图在 snmp4j 上做例子，但它没有用。

我花了一些时间，但我终于想出了如何使用 SNMP4J 发送陷阱：希望有帮助..
public static void main(String[] args) throws Exception {
// Create PDU
PDU trap = new PDU();
trap.setType(PDU.TRAP);
OID oid = new OID("1.2.3.4.5");
trap.add(new VariableBinding(SnmpConstants.snmpTrapOID, oid));
trap.add(new VariableBinding(SnmpConstants.sysUpTime, new TimeTicks(5000))); // put your uptime here
trap.add(new VariableBinding(SnmpConstants.sysDescr, new OctetString("System Description")));
//Add Payload
Variable var = new OctetString("some string");
trap.add(new VariableBinding(oid, var));
// Specify receiver
Address targetaddress = new UdpAddress("10.101.21.32/162");
CommunityTarget target = new CommunityTarget();
target.setCommunity(new OctetString("public"));
target.setVersion(SnmpConstants.version2c);
target.setAddress(targetaddress);
// Send
Snmp snmp = new Snmp(new DefaultUdpTransportMapping());
snmp.send(trap, target, null, null);
}

我为此使用SNMP4J。
这个javadoc 可能会帮助您编写代码。您可以使用Snmp.trap()方法
编辑：
好吧，我现在没有自己的代码，但你可以参考这个。您必须使用 Snmp.notify() 发送 V2 陷阱而不是 Snmp.trap() 因为 trap() 仅支持发送 V1 陷阱。

发送陷阱 V1 和通知 V2 的一个很好的示例。我只需要将端口修改为 162 以及为版本 V1 和 V2 设置 sysUpTime 的方式。
用 snmp4j-1.10.1 和 snmp4j-2.1.0 测试。

我会去 snmp4j 库http://www.snmp4j.org/。
import org.snmp4j.*;
import org.snmp4j.event.*;
...
CommunityTarget target = new CommunityTarget();
target.setCommunity(new OctetString("public"));
target.setAddress(targetAddress);
target.setVersion(SnmpConstants.version2c);
PDU request = new PDU();
request.setType(PDU.V2TRAP);
request.setGenericTrap(PDUv2.COLDSTART);
Snmp snmp = new Snmp(new DefaultUdpTransportMapping());
snmp.listen();
snmp.sendPDU(request, target, null, listener);
