【Eureka&springCloud】java.net.UnknownHostException

Question

I registered two services under Eureka. Resttemplate calls the interface of another service through the service name of one service. The following error occurred. If I call directly through IP, there will be no error. enter image description here

I have annotated @ loadlanced under resttemplate to confirm that there is no error in the service name. Please ask us how to solve this bug
