SpringBoot动态域名解析的实现
前期准备
- 一个动态公网IPv4/v6地址（v4需要到宽带所属营业厅自行付费申请，v6则保证公网IP即可）
- 域名（腾讯云）
- 一个Springboot项目
Maven依赖引入
<!--lombok-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<scope>provided</scope>
</dependency>
<!-- hutool工具库 -->
<dependency>
<groupId>cn.hutool</groupId>

<dependency>

</dependency>本地公网IPv4获取
笔者电脑网卡比较多，一个个测试比较麻烦且可能出现BUG，所以偷了个懒直接调用别人写好的接口点击查询本地IPv4地址
静态工具类 IPUtils.java
public class IPUtils {
public static String ip(){
HttpResponse httpres = HttpUtil.createGet("https://api.vvhan.com/api/getIpInfo").execute();
HashMap hashmap = JSONUtil.toBean(httpres.body().toString(), HashMap.class);
return hashmap.get("ip").toString();
}
}pojo实体类与静态配置文件
TencentCloud.java
@Data
@Component
@ConfigurationProperties(prefix = "tencentcloud")
public class TencentCloud {
private String secretId;
private String secretKey;
}AnalysisInfo.java
@Data
@Component
@ConfigurationProperties(prefix = "analysisinfo")
public class AnalysisInfo {
private String domain;
private String subDomain;
private Long recordId;
private String recordLine;
private String recordLineId;
private String url;
}application.properties（请自行修改值）
#腾讯云api密钥信息（打开链接获取：https://console.cloud.tencent.com/cam/capi）
tencentcloud.secret-id=腾讯云secret-id
tencentcloud.secret-key=腾讯云secret-key
#DNS解析默认配置信息
analysisinfo.domain=“你的域名”
analysisinfo.sub-domain=“主机记录值”
analysisinfo.record-id="打开链接查询https://cloud.tencent.com/document/api/1427/56166"
analysisinfo.record-line=默认
analysisinfo.record-line-id=0
analysisinfo.url=dnspod.tencentcloudapi.comservice接口以及实现类
DnsService.java 接口类
public interface DnsService {
public String dnsAnalysis() throws TencentCloudSDKException;
}DnsServiceImpl.java 接口实现类
@Service("dnsService")
public class DnsServiceImpl implements DnsService {
@Autowired
private TencentCloud tencentCloud;
@Autowired
private AnalysisInfo analysisInfo;
public String dnsAnalysis() throws TencentCloudSDKException {
Credential cred = new Credential(tencentCloud.getSecretId(), tencentCloud.getSecretKey());
HttpProfile httpProfile = new HttpProfile();
httpProfile.setEndpoint(analysisInfo.getUrl());
ClientProfile clientProfile = new ClientProfile();
clientProfile.setHttpProfile(httpProfile);
DnspodClient client = new DnspodClient(cred, "", clientProfile);
// 实例化一个请求对象,每个接口都会对应一个request对象
ModifyDynamicDNSRequest req = new ModifyDynamicDNSRequest();
req.setDomain(analysisInfo.getDomain());
req.setSubDomain(analysisInfo.getSubDomain());
req.setRecordId(analysisInfo.getRecordId());
req.setRecordLine(analysisInfo.getRecordLine());
req.setRecordLineId(analysisInfo.getRecordLineId());
req.setValue(IPUtils.ip());
// req.setTtl(600L);
// 返回的resp是一个ModifyDynamicDNSResponse的实例，与请求对象对应
ModifyDynamicDNSResponse resp = client.ModifyDynamicDNS(req);
// return ModifyDynamicDNSResponse.toJsonString(resp);
return "修改解析记录值成功！";
}
}controller控制器
DnsController.java
@RestController
@RequestMapping("dnscontroller")
public class DnsController {
@Autowired
private DnsService dnsService;
@GetMapping("/dns")
public String dns() throws TencentCloudSDKException {
return dnsService.dnsAnalysis();
}
}定时器
笔者后续会放入cloud服务中写自己的Demo，所以采用api定时调用的形式。
DNSTimerConfig.java
@Configuration
@EnableScheduling
public class DNSTimerConfig {
@Scheduled(cron = "0 0 0/1 * * ? ") // 每一小时执行一次
public static void go() {
System.out.println("开始");
HttpResponse httpres = HttpUtil.createGet("http://127.0.0.1:8080/dnscontroller/dns").execute();
System.out.println(httpres.body().toString());
}

弹性公网 IP
弹性公网 IP（Elastic IP，EIP）是可以独立购买和持有，且在某个地域下固定不变的公网 IP 地址，可以与 CVM、NAT 网关、弹性网卡和高可用虚拟 IP 等云资源绑定，提供访问公网和被公网访问能力；还可与云资源的生命周期解耦合，单独进行操作；同时提供多种计费模式，您可以根据业务特点灵活选择，以降低公网成本。
