Retry zuul request with new Auth header for 401 status code

[pdondapa]

I need to catch '401' Un-Authorized status code of the zuul requests and retry using a new Access token

I am using spring-cloud-starter-zuul for routing the requests, I am adding the Access token in PreRequestFilter from Spring Session.. I need to catch the '401' Un-Authorized status code for the expired tokens and retry the same request using a new access token created using the existing token..

Here is my zuul configuration
zuul.routes.service1-api.url=http://service1:8080/api/v1/ zuul.routes.service2-api.url=http://service2:8080/api/v1/ zuul.routes.service3-api.url=http://service3:8080/api/v1/ zuul.host.connect-timeout-millis=60000 zuul.host.socket-timeout-millis=60000 zuul.add-proxy-headers=false ribbon.eureka.enabled=false

In my PreRequestFilter

@Override public Object run() { this.setHeadersToContext(ctx); return null; }
