spring-cloud - Zuul 将 hystrix 隔离策略默认为 SEMAPHORE

Question

这是我之前问题的延续，在我的 hystrix 仪表板中，线程池部分不断加载:- Hystrix Dashboard with Turbine issue

为什么zuul强制hystrix的隔离策略是SEMAPHORE。我尝试将配置添加到我的 application.yml 但它仍然忽略它并使用 SEMAPHORE。我在这里缺少什么吗？或者我如何将它从 SEMAPHORE 更改为 THREAD。

Answer 1

zuul.ribbonIsolationStrategy=线程

可以使用上面的命令强制ZUUL使用THREAD策略
