Question

这是我之前的问题的继续，在我的hystrix仪表板中，线程池部分继续加载： - Hystrix Dashboard with Turbine issue

为什么zuul迫使hystrix的隔离策略为SEMAPHORE。我尝试将配置添加到我的application.yml但仍忽略它并使用SEMAPHORE。有什么我在这里失踪的东西。或者我如何将其从SEMAPHORE更改为THREAD。

Answer 1

zuul.ribbonIsolationStrategy=THREAD

您可以使用上述命令强制ZUUL使用THREAD策略

Answer 2

为什么zuul迫使hystrix的隔离策略为SEMAPHORE

请参阅TTFB。

//我们希望默认为信号量隔离，因为它包装了
  // 2其他已经线程隔离的命令

Zuul违约hystrix隔离策略到SEMAPHORE
