特定艙壁配置

與提供預設“Bulkhead”或“ThreadPoolBulkhead”配置類似，您可以建立一個 Customizer bean，該 bean 會傳遞一個 Resilience4jBulkheadProvider。

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

除了配置要建立的艙壁外，您還可以在艙壁和執行緒池艙壁建立後但在返回給呼叫者之前對其進行自定義。為此，您可以使用 addBulkheadCustomizer 和 addThreadPoolBulkheadCustomizer 方法。

艙壁示例

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

執行緒池艙壁示例

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