java - Hystrix 后备方法不运行

Question

我对关闭的端点进行了调用，但是 hystrix 不执行回退方法，并引发异常：

java.util.concurrent.ExecutionException: org.springframework.web.client.ResourceAccessException: 
I/O error on GET request for "http://localhost:8080/wallet/customers/100/cards/": Conexão recusada (Connection refused); nested exception is java.net.ConnectException: Conexão recusada (Connection refused)

有人知道是否缺少任何配置吗？

我的主要

@EnableCircuitBreaker
@SpringBootApplication
public class WalletPaymentApplication {

    public static void main(String[] args) {
        SpringApplication.run(WalletPaymentApplication.class, args);
    }
}

和我的服务：

public PaymentMethodsData setUpPaymentMethods(String customerId) {
    return new PaymentMethodsData(getCardList(customerId));
}

@HystrixCommand(fallbackMethod = "getCardListCircuitBreaker")
public List<SummaryCardData> getCardList(String customerId) {
    return template.getForObject(configureUrl(cardUrl), CardRows.class, customerId).getRows();
}

public List<SummaryCardData> getCardListCircuitBreaker(String customerId){
    return new ArrayList<>();
}

Answer 1

要启用@HystrixCommand(fallbackMethod = "getCardListCircuitBreaker")，您必须从另一个 bean 调用您的方法。然后注释将正常工作。
