断路器特性配置

你可以配置断路器和时间限制器配置或实例，出现在你的应用配置属性文件里。属性配置的优先级高于 Java定制器配置。spring-doc.cadn.net.cn

优先级从上到下递减。spring-doc.cadn.net.cn

Method（id）配置 - 针对特定方法或作spring-doc.cadn.net.cn
服务（组）配置——针对特定应用服务或作spring-doc.cadn.net.cn
全局默认配置spring-doc.cadn.net.cn

ReactiveResilience4JCircuitBreakerFactory.create(String id, String groupName)

全局默认属性配置

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

    configs:
        default:
            timeoutDuration: 5s
            cancelRunningFuture: true

禁用时间限制器

默认情况下，时间限制器启用了，并且每次执行都有时间限制。该时间限制要么被明确定义，要么是默认时间限制（由io.github.resilience4j.timelimiter.TimeLimiterConfig#ofDefaults）被使用。spring-doc.cadn.net.cn

这时间限制器可以通过设置属性来全局禁用spring.cloud.circuitbreaker.resilience4j.disable-time-limiter自true.spring-doc.cadn.net.cn

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

时间限制器也可以在特定组或实例中禁用，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

这些禁用选项时间限制在春季-云断路器并适用于基础和无功断路器的实现。spring-doc.cadn.net.cn

禁用的优先顺序为：实例 > 群 > 全球.基于上述配置，实例B和第一组有时间限制器但被禁用实例A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，未被设置，时间限制为剩余的断路器实例和组启用。spring-doc.cadn.net.cn
