使用discoveryClient.getInstances("caas-core-svc")得到如下结果；

[KubernetesServiceInstance{instanceId='9f120881-4176-48b4-bcfc-678ae8f4a64d', serviceId='caas-core-svc', host='100.64.196.216', port=8080, uri=http://100.64.196.216:8080, secure=false, namespace=caas-system, cluster=null, metadata={null=8080, adp.aliyuncs.com/component-version=1.5.3-0, adp.aliyuncs.com/component-app-version=1.5.3, adp.aliyuncs.com/application-name=quota-test, adp.aliyuncs.com/component-name=aecp, adp.aliyuncs.com/component-type=aecp, adp.aliyuncs.com/application-namespace=default, adp.aliyuncs.com/component-namespace=acs-system, adp.aliyuncs.com/component-provider=}}]

image 其中key是null，Jackson解析是会报错，是不是这个原因导致的？？

I don't think this is a client error. But more importantly this looks like it is running in a unit test?

We need much more detail on the environment and the stacktraces to see if there is a problem here in the client, but I suspect that there's a problem with your server.
