与证明默认的 'Bulkhead' 或 'ThreadPoolBulkhead' 配置类似，您可以创建一个 bean 传递 .CustomizerResilience4jBulkheadProvider

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

除了配置创建的隔板外，您还可以自定义隔板和线程池隔板 已创建，但在返回给调用方之前。为此，您可以使用 and 方法。addBulkheadCustomizeraddThreadPoolBulkheadCustomizer

舱壁示例

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

线程池隔板示例

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