RetryableException: Read timed out executing导致服务假死无响应

最近发现Plan这个微服务经常会无响应，后来发现是task微服务会调用plan的某个接口，经常报错如下异常，然后time out后又30秒再次发起重试而这个业务处理时间1分钟-2小时都有可能

所以把plan微服务线程池占满导致无响应

解决方法：

网上查了很多，试了如下配置都无效

feign:
client:
config:
default:
connectTimeout: 60000
readTimeout: 60000


#hystrix的超时时间
hystrix:
command:
default:
execution:
timeout:
enabled: true
isolation:
thread:
timeoutInMilliseconds: 30000


feign.hystrix.enabled: true
hystrix 熔断机制
hystrix:
shareSecurityContext: true
command:
default:
circuitBreaker:
sleepWindowInMilliseconds: 100000
forceClosed: true
execution:
isolation:
thread:
timeoutInMilliseconds: 600000

#ribbon的超时时间
ribbon:
ReadTimeout: 30000
ConnectTimeout: 30000

 

 

 

 

后来发现因为我们升级到了最新的springboot

然后使用了最新的openfeign

Spring Cloud OpenFeign 中文文档 (springdoc.cn)

所以应该如下配置：

spring:
  cloud:
    openfeign:
      client:
        config:
          default:
            connectTimeout: 20000000
            readTimeout: 20000000
            loggerLevel: basic
