SpringCloud进阶–Zuul与Ribbon的Timeout配置

SpringCloud进阶–Zuul与Ribbon的Timeout配置

  1. Springcloud第一次请求超时

    当通过zuul第一次请求微服务中的服务时,由于也是通过ribbon的http请求去请求原子服务,第一次请求需要加载一些路由基本信息,会报SocketTimeoutException: Read timed out超时错误。

,查看源码AbstractLoadBalancingClient发现可以通过

#ribbon超时设置
ribbon.ReadTimeout=30000
ribbon.ConnectTimeout=30000

,设置超时时间,其中ConnectTimeout代表建立stocket连接的超时时间,readtimeout为连接建立后,服务返回值的超时时间。

 

  1. Hystrix小于ribbon超时时间

我的hystrix的超时时间是设置60000,发现会提示

The Hystrix timeout of 60000ms for the command HJ-RiskRule-Edge is set lower than the combination of the Ribbon read and connect timeout, 180000ms.

#hystrix超时设置
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=60000
#单独服务的超时设置
#"hystrix.command." + commandKey + ".execution.isolation.thread.timeoutInMilliseconds"

通过源码发现,原来ribbon中的超时时间算法是,其中maxAutoRetries 是每台服务器最多重试次数,但是首次调用不包括在内,maxAutoRetriesNextServer是最多重试多少台服务器。

ribbonTimeout = (ribbonReadTimeout + ribbonConnectTimeout) * (maxAutoRetries + 1) * (maxAutoRetriesNextServer + 1);

protected static int getHystrixTimeout(IClientConfig config, String commandKey) { int ribbonTimeout = getRibbonTimeout(config, commandKey); DynamicPropertyFactory dynamicPropertyFactory = DynamicPropertyFactory.getInstance(); int defaultHystrixTimeout = dynamicPropertyFactory.getIntProperty("hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds", 0).get(); int commandHystrixTimeout = dynamicPropertyFactory.getIntProperty("hystrix.command." + commandKey + ".execution.isolation.thread.timeoutInMilliseconds", 0).get(); int hystrixTimeout; if(commandHystrixTimeout > 0) { hystrixTimeout = commandHystrixTimeout; } else if(defaultHystrixTimeout > 0) { hystrixTimeout = defaultHystrixTimeout; } else { hystrixTimeout = ribbonTimeout; } if(hystrixTimeout < ribbonTimeout) { LOGGER.warn("The Hystrix timeout of " + hystrixTimeout + "ms for the command " + commandKey + " is set lower than the combination of the Ribbon read and connect timeout, " + ribbonTimeout + "ms."); } return hystrixTimeout; }

通过以上设置,第一次请求时,已经不会再报超时错误。
