摘　　要：微服务架构中各个服务之间互相依赖互相调用,其依赖链通常比较复杂,若某个调用失败的服务未得到隔离或者有效控制,必将影响整个系统的稳定性和健壮性。因此,提高微服务架构的服务容错能力显得至关重要。Hystrix是处理和控制远程系统、服务和第三方库节点的框架,该框架具备了服务降级、服务熔断、线程隔离以及服务监控等强大功能,是提升微服务架构容错保护能力的首选。断路器是Hystirx框架的核心组件,它的决策熔断在服务容错中起到了举足轻重的作用。文章分析Hystirx的熔断原理和工作流程,并采用Turbine来汇集Security服务监控消息,实现了断路器、线程隔离等一系列的服务保护功能。In the micro-service architecture, each service is mutually dependent on each other. The dependency chain is usually more complicated. If a service fails to be isolated or effectively controlled, it will affect the stability and robustness of the entire system. Therefore, improving the service fault tolerance of the microservices architecture is crucial. Hystrix is the framework for processing and controlling remote systems, services, and third-party library nodes. It has powerful features such as service downgrade, service buck, thread isolation, and service monitoring. It is the first choice to improve the fault tolerance of microservices architecture. The circuit breaker is the core component of the Hystirx framework, and its decision-making fuse plays a pivotal role in service fault tolerance. The article analyzes the melting principle and workflow of Hystirx, and uses Turbine to collect security service monitoring messages, and implements a series of service protection functions such as circuit breaker and thread isolation.
