用springboot开发一个snmp采集程序，并最终生成拓扑图 (二）

其实不用springboot我们也可以开发snmp采集，只是为了后面的需要我们才要用上springboot, 一开始可以直接用java就够了

先后尝试了vscode, idea老版，最后使用idea社区版与通义灵码来做这个事，这事自己找个顺手的就好，只是我好久不弄，不得不先从搭开发环境开始

需要ctrl+shift+O 做下maven sync

Main.java

ini 复制代码

package org.example;

import org.snmp4j.*;
import org.snmp4j.event.ResponseEvent;
import org.snmp4j.mp.SnmpConstants;
import org.snmp4j.smi.*;
import org.snmp4j.transport.DefaultUdpTransportMapping;

//TIP To <b>Run</b> code, press <shortcut actionId="Run"/> or
// click the <icon src="AllIcons.Actions.Execute"/> icon in the gutter.
public class Main {
    public static void main(String[] args) {
        String address = "udp:192.168.10.252/161";
        String community = "public";
        String oid = "1.3.6.1.2.1.1.1.0";
        try{
            TransportMapping transport = new DefaultUdpTransportMapping();
            transport.listen();
            Snmp snmp = new Snmp(transport);

            PDU pdu = new PDU();
            pdu.add(new VariableBinding(new OID(oid)));
            pdu.setType(PDU.GET);

            Address targetAddress = GenericAddress.parse(address);
            Target target = new CommunityTarget(targetAddress, new OctetString(community));
            target.setRetries(2);
            target.setTimeout(1500);
            target.setVersion(SnmpConstants.version2c);

            ResponseEvent response = snmp.send(pdu, target);
            PDU responsePDU = response.getResponse();
            if (responsePDU!=null){
                System.out.println("Response: " + responsePDU.get(0).getVariable());

            }else {
                System.out.println("Timeout");
            }
            snmp.close();
        }catch(Exception e){
            e.printStackTrace();
        }

    }
}

OK shift+F10执行会得到结果
