Causes and solutions:

It can be seen that the http request error timeout is reported. Feign calls are divided into two layers, ribbon calls and hystrix calls. The higher version of hystrix is ​​turned off by default, so you can set ribbon in the configuration file.

#Request processing timeout time
 : 120000
 #Timeout time for requesting connection
 : 30000

If hystrix is ​​enabled, the hystrix timeout error is reported as shown in the figure below:

FeignDemo#demo() timed-out and no fallback available. There is still a difference between the timeout error and the ribbon

: FeignDemo#demo() timed-out and no fallback available.

Solution:

: true
 hystrix circuit breaker mechanism
 hystrix:
   shareSecurityContext: true
   Command:
     default:
       circuitBreaker:
         sleepWindowInMilliseconds: 100000
         forceClosed: true
       execution:
         isolation:
           thread:
             timeoutInMilliseconds: 600000
