我的部分配置檔案:

#設定熔斷是為6秒
ribbon:
    ConnectTimeout: 60000
    ReadTimeout: 60000
    eureka:
        enabled: true
#關閉超時時間
hystrix:
    command:
        default:
            execution:
                timeout:
                    enabled: false

百度搜索,他們說需要配置的,我這裡都早已經配置好了,發現以上並沒有解決我的問題:

類似這種,我用路由去訪問請求:http://localhost:9999/service-a/

xx/xx

zuul:
  routes:
    api-a:
      path: /service-a/**
      serviceId: service-a

結果仍然是上面的錯誤。

需要在微服務的應用服務層啟動類上開啟兩個註解。
