Default Configuration
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
If you would like to configure the ExecutorService
which executes the circuit breaker you can do so using the Resilience4JCircuitBreakerFactory
.
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);
};
}
