Specific Bulkhead Configuration

与提供默认 Bulkhead 或 ThreadPoolBulkhead 配置类似，您可以创建一个 Customizer Bean，该 Bean 传递给 Resilience4jBulkheadProvider。

@Bean
public Customizer<Resilience4jBulkheadProvider> slowBulkheadProviderCustomizer() {
    return provider -> provider.configure(builder -> builder
        .bulkheadConfig(BulkheadConfig.custom().maxConcurrentCalls(1).build())
        .threadPoolBulkheadConfig(ThreadPoolBulkheadConfig.ofDefaults()), "slowBulkhead");
}

除了配置创建的 Bulkhead 之外，您还可以自定义 Bulkhead 和线程池 Bulkhead 在创建后且返回给调用者之前。为此，您可以使用 addBulkheadCustomizer 和 addThreadPoolBulkheadCustomizer 方法。

Bulkhead Example

@Bean
public Customizer<Resilience4jBulkheadProvider> customizer() {
    return provider -> provider.addBulkheadCustomizer(bulkhead -> bulkhead.getEventPublisher()
        .onCallRejected(slowRejectedConsumer)
        .onCallFinished(slowFinishedConsumer), "slowBulkhead");
}

Thread Pool Bulkhead Example

@Bean
public Customizer<Resilience4jBulkheadProvider> slowThreadPoolBulkheadCustomizer() {
    return provider -> provider.addThreadPoolBulkheadCustomizer(threadPoolBulkhead -> threadPoolBulkhead.getEventPublisher()
        .onCallRejected(slowThreadPoolRejectedConsumer)
        .onCallFinished(slowThreadPoolFinishedConsumer), "slowThreadPoolBulkhead");
}
