我对关闭的端点进行调用,但是 hystrix 不执行回退方法,并抛出异常:
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);
}
}
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<>();
}
要启用
@HystrixCommand(fallbackMethod = "getCardListCircuitBreaker")
,您必须从另一个 bean 调用您的方法。然后注释就可以正常工作了。
如果有人解决了这个问题,请分享,应该如何调用。
