此版本仍在开发中，尚未被视为稳定版本。对于最新的稳定版本，请使用 Spring-Cloud-CircuitBreaker 3.1.3！spring-doc.cadn.net.cn

默认配置

要为所有断路器提供默认配置，请创建一个Customizerbean 的 bean 传递一个Resilience4JCircuitBreakerFactory或ReactiveResilience4JCircuitBreakerFactory. 这configureDefaultmethod 可用于提供默认配置。spring-doc.cadn.net.cn

@Bean
public Customizer<Resilience4JCircuitBreakerFactory> defaultCustomizer() {
	return factory -> factory.configureDefault(id -> new Resilience4JConfigBuilder(id)
			.timeLimiterConfig(TimeLimiterConfig.custom().timeoutDuration(Duration.ofSeconds(4)).build())
			.circuitBreakerConfig(CircuitBreakerConfig.ofDefaults())
			.build());
}

反应式示例

@Bean
public Customizer<ReactiveResilience4JCircuitBreakerFactory> defaultCustomizer() {
	return factory -> factory.configureDefault(id -> new Resilience4JConfigBuilder(id)
			.circuitBreakerConfig(CircuitBreakerConfig.ofDefaults())
			.timeLimiterConfig(TimeLimiterConfig.custom().timeoutDuration(Duration.ofSeconds(4)).build()).build());
}

自定义 ExecutorService

如果要配置ExecutorService它执行断路器，您可以使用Resilience4JCircuitBreakerFactory.spring-doc.cadn.net.cn

例如，如果您想使用上下文感知ExecutorService您可以执行以下作。spring-doc.cadn.net.cn

@Bean
public Customizer<ReactiveResilience4JCircuitBreakerFactory> defaultCustomizer() {
	return factory -> {
		ContextAwareScheduledThreadPoolExecutor executor = ContextAwareScheduledThreadPoolExecutor.newScheduledThreadPool().corePoolSize(5)
			.build();
		factory.configureExecutorService(executor);
	};
}
