2019-09-19 17:46:48.283 [http-nio-7777-exec-3] WARN o.s.c.n.z.f.route.support.AbstractRibbonCommand - The Hystrix timeout of 5000ms for the command SERVICE is set lower than the combination of the Ribbon read and connect timeout, 400000ms.
分析：code
Ribbon 總時間ribbonTimeout = (ribbonReadTimeout + ribbonConnectTimeout) * (maxAutoRetries + 1) * (maxAutoRetriesNextServer + 1);
筆者這裏的具體值爲：（5000+5000）*（1+1）*（1+1）=40000；
而Hystrix 時間爲：5000，具體辦法也好辦，在配置文件中修改超時爲：
hystrix: command: default: execution: isolation: thread: timeoutInMilliseconds: 40000
或者修改ribbon配置：blog
AUSERVICE: #這是ribion要請求的serviceID ribbon: ReadTimeout: 2000 ConnectTimeout: 2000 MaxAutoRetries: 0 MaxAutoRetriesNextServer: 0
即：(2000+2000)*(0+1)*(0+1)=4000<5000也可。io
