[stereo720712]

Dear Sir:
I am trying to practice spring cloud and oauth2 by your code.
And I found a problem :
When token is expired and go to refresh token, it failed.
After trace code, i found the final http request is still htttp://service-name:port?parameter.
So it's get faild at :
OAuth2TokenRelayFilter.getAccessToken().
Can you help me to find the reason why the service name not change to real http address to
execute
Very thank you and appreciate.

i found the problem is because the LoadBalancerInterceptor not work when a refresh token request invoke, interceptor become null, why ?
