利⽤springcloudeureka监控服务，宕机发邮件提醒，以及解决邮件重复发送实例  先给eureka客户端配置：
#注册中⼼地址
eureka.client.service-url.defaultZone=localhost:9999/eureka/
#服务过期时间配置，超过这个时间没有接收到⼼跳，服务端就会将这个实例剔除
eureka.instance.lease-expiration-duration-in-seconds=90
#服务刷新时间配置，每隔这个时间会主动⼼跳⼀次
eureka.instance.lease-renewal-interval-in-seconds=30
  再给服务端配置：
#本机端⼝
server.port=9999
spring.application.name=order_moniter
spring.profiles.active=dev
#是否向注册中⼼注册⾃⼰
ister-with-eureka=false
#是否从注册中⼼查询服务
eureka.client.fetch-registry=false
#关闭⾃我保护
able-self-preservation=false
#服务端每隔1分钟刷新服务列表，将⽆效服务剔除
eureka.server.eviction-interval-timer-in-ms=60000
#邮件
spring.mail.host=smtp.163
spring.mail.username=tangseng2019@163
spring.mail.password=wlf123456
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.quired=true
spring.mail.properties.able=true
spring.mail.default-encoding=UTF-8
mail.from=${spring.mail.username}
<=sunwukong2019@126;zhubajie2019@126
  接着给eureka服务端加上服务下线监听：
import der_monitor.service.MailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloudflix.eureka.server.event.EurekaInstanceCanceledEvent;
import t.event.EventListener;
import org.springframework.stereotype.Component;
SimpleDateFormat;
@Component
public class EurekaListener {
private final static SimpleDateFormat SF = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
@Autowired
MailService mailService;
@EventListener
public void listen(EurekaInstanceCanceledEvent event) {
StringBuilder sb = new StringBuilder();
sb.append("服务ID=");
sb.ServerId());
sb.Property("line.seperator", "\n"));
sb.append("应⽤名=");
sb.AppName());
sb.Property("line.seperator", "\n"));
sb.append("时间=");
sb.append(SF.Timestamp()));
mailService.sendSimpleMail("⽕烧眉⽑你的服务挂了，快来救⽕~~~", sb.toString());
}
}
  MailService类详见。
  好了，现在分别启动eureka服务端和客户端，然后把客户端停掉，观察服务端是否发送邮件：

  客户端⽇志太多，删掉了⼀些，按eureka客户端的配置，客户端每30秒发送⼀次⼼跳，在续租时间90秒过了之后仍未收到⼼跳则认为服务实例下线，服务端每隔⼀分钟刷新
服务实例，发现实例被移除则发送邮件通知相关⼈。
  但现在有个问题：邮件会重复发送。我们不希望被垃圾邮件骚扰，重构下监听类：
@Slf4j
@Component
public class EurekaListener {
private final static SimpleDateFormat SF = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
private final static Set<String> services = new HashSet<>();
@Autowired
MailService mailService;
@EventListener
public void listen(EurekaInstanceCanceledEvent event) throws InterruptedException {
String serviceId = ServerId();
String appName = AppName();
// 已经下线的服务，我们不需要重复发送邮件，外层拦截
if (ains(serviceId + appName)) {
log.warn("[Out] This serviceId has canceled, serviceId : {}, appName : {}", serviceId, appName);
return;
}
synchronized (this) {
// 已经下线的服务，我们不需要重复发送邮件，内层拦截
if (ains(serviceId + appName)) {
log.warn("[In] This serviceId has canceled, serviceId : {}, appName : {}", serviceId, appName);
return;
}
// ⾸次下线，添加发送邮件标志
services.add(serviceId + appName);
// ⽣成邮件内容邮件
StringBuilder sb = new StringBuilder();
sb.append("服务ID=");
sb.append(serviceId);
sb.Property("line.seperator", "\n"));
sb.append("应⽤名=");
sb.append(appName);
sb.Property("line.seperator", "\n"));
sb.append("时间=");
sb.append(SF.Timestamp()));
mailService.sendSimpleMail("⽕烧眉⽑你的服务挂了，快来救⽕~~~", sb.toString());
}
}
@EventListener
public void listen(EurekaInstanceRegisteredEvent event) {
String serviceId = InstanceInfo().getInstanceId();
String appName = InstanceInfo().getAppName();
// 服务重启恢复后，删掉发送邮件标志
if (InstanceInfo().getStatus().equals(InstanceInfo.InstanceStatus.UP) &&
log.warn("register service again, services'size : {}, delete serviceKey : {}",
services.size(), serviceId + appName);
}
}
}
  重新测试，启动服务端和客户端后，杀死客户端，再启动客户端再杀死，看看服务端的⽇志：
