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/
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。
