我们部门有一套k8s服务、然后grpc服务下线的时候不是用的jvm hook来通知注册中心嘛。就会造成下线不稳定、有时候不能主动下线成功。

做个ApplicationListener, 手动反注册,然后sleep阻塞一段时间,实现延迟下线,
k8s要配置terminationGracePeriodSeconds
PolarisAutoServiceRegistration polarisAutoServiceRegistration = SpringContextHolder.getApplicationContext().getBean(PolarisAutoServiceRegistration.class);
polarisAutoServiceRegistration.stop();
Thread.sleep(10000);

后续会在 polaris-java 提供标准的无损上下线 API 设计，暂时先移到 grpc-java-polaris
