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。

To provide a default configuration for all of your circuit breakers create a Customizer bean that is passed a Resilience4JCircuitBreakerFactory or ReactiveResilience4JCircuitBreakerFactory. The configureDefault method can be used to provide a default configuration.

@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。

If you would like to configure the ExecutorService which executes the circuit breaker you can do so using the Resilience4JCircuitBreakerFactory.

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

For example if you would like to use a context aware ExecutorService you could do the following.

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