To Reproduce
Steps to reproduce the behavior.

webflux

1. The authorization service is started first, and then the gateway is started

3. The authorization service is stopped based on the above, and an exception is called. Restart the authorization service. You keep getting an error no matter how you call it

webmvc

1. webmvc can't parse directly, no matter how you operate it.And start to report an error, can not start directly
