Default Configuration

若要为所有断路器提供默认配置，请创建一个 Customizer Bean，该 Bean 传递给 Resilience4JCircuitBreakerFactory 或 ReactiveResilience4JCircuitBreakerFactory。configureDefault 方法可用于提供默认配置。

@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());
}

Reactive Example

@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());
}

Customizing The ExecutorService

如果您想配置执行断路器的 ExecutorService，可以使用 Resilience4JCircuitBreakerFactory 来配置。

例如，如果您想使用上下文化感知的 ExecutorService，可以执行以下操作。

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