断路器属性配置

您可以配置CircuitBreaker和TimeLimiter应用程序的配置文件属性文件中的配置或实例。 属性配置的优先级高于 JavaCustomizer配置。spring-doc.cadn.net.cn

优先级从上到下降序。spring-doc.cadn.net.cn

ReactiveResilience4JCircuitBreakerFactory.create(String id, String groupName)
Resilience4JCircuitBreakerFactory.create(String id, String groupName)

全局默认属性配置

resilience4j.circuitbreaker:
    configs:
        default:
            registerHealthIndicator: true
            slidingWindowSize: 50

resilience4j.timelimiter:
    configs:
        default:
            timeoutDuration: 5s
            cancelRunningFuture: true

         timeoutDuration: 2s
         cancelRunningFuture: true
     backendB:
         timeoutDuration: 1s
         cancelRunningFuture: false

禁用TimeLimiter

默认情况下，TimeLimiter启用，并且每次执行都有时间限制。此时间限制是显式定义的，也可以是默认时间限制（由io.github.resilience4j.timelimiter.TimeLimiterConfig#ofDefaults） 被使用。spring-doc.cadn.net.cn

这TimeLimiter可以通过设置属性spring.cloud.circuitbreaker.resilience4j.disable-time-limiter自true.spring-doc.cadn.net.cn

spring:
	cloud:
		circuitbreaker:
			resilience4j:
				disable-time-limiter: true

TimeLimiter也可以使用spring.cloud.circuitbreaker.resilience4j.disable-time-limiter-map如下：spring-doc.cadn.net.cn

spring:
	cloud:
		circuitbreaker:
			resilience4j:
				disable-time-limiter-map:
					group1: true
					instanceA: false
					instanceB: true

这些用于禁用的选项TimeLimit在spring-cloud-circuitbreaker并适用于基本和无功断路器实现。spring-doc.cadn.net.cn

禁用的优先级顺序为：instance > group > global.基于上述配置，instanceB和group1有TimeLimiterdisabled 但instanceA已启用。对于所有其他实例和组，它将回退到全局设置的值spring.cloud.circuitbreaker.resilience4j.disable-time-limiter如果spring.cloud.circuitbreaker.resilience4j.disable-time-limiter默认情况下，未设置TimeLimit为其余断路器实例和组启用。spring-doc.cadn.net.cn
