默认配置

要为所有断路器提供默认配置，请创建一个传递或的 bean。该方法可用于提供默认配置。CustomizerResilience4JCircuitBreakerFactoryReactiveResilience4JCircuitBreakerFactoryconfigureDefaultspring-doc.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

如果要配置执行断路器的，可以使用来实现。ExecutorServiceResilience4JCircuitBreakerFactoryspring-doc.cn

例如，如果您想使用上下文感知，您可以执行以下操作。ExecutorServicespring-doc.cn

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