problem description
the top-level service uses fegin to invoke the interface downloaded by the underlying service (which is quite time-consuming), resulting in a Hystrix timeout circuit breaker.

this is the picture captured last time. It can"t be run without the company now.
what result do you expect? What is the error message actually seen?
do you annotate the interface to generate a specific circuit breaker strategy to cancel the circuit breaker, or prolong the time to trigger the circuit breaker
