最近發現Plan這個微服務經常會無響應，後來發現是task微服務會呼叫plan的某個介面，經常報錯如下異常，然後time out後又30秒再次發起重試而這個業務處理時間1分鐘-2小時都有可能
所以把plan微服務執行緒池佔滿導致無響應

解決方法：
網上查了很多，試瞭如下配置都無效
feign:
client:
config:
default:
connectTimeout: 60000
readTimeout: 60000
#hystrix的超時時間
hystrix:
command:
default:
execution:
timeout:
enabled: true
isolation:
thread:
timeoutInMilliseconds: 30000
feign.hystrix.enabled: true
hystrix 熔斷機制
hystrix:
shareSecurityContext: true
command:
default:
circuitBreaker:
sleepWindowInMilliseconds: 100000
forceClosed: true
execution:
isolation:
thread:
timeoutInMilliseconds: 600000
#ribbon的超時時間
ribbon:
ReadTimeout: 30000
ConnectTimeout: 30000
後來發現因為我們升級到了最新的springboot
然後使用了最新的openfeign
Spring Cloud OpenFeign 中文文件 (springdoc.cn)
所以應該如下配置：
spring:
cloud:
openfeign:
client:
config:
default:
connectTimeout: 20000000
readTimeout: 20000000
loggerLevel: basic
