我已将我的 zuul 代理配置为与我的微服务的多个实例一起使用。我唯一做的就是将ribbon.listOfServers 关键字添加到我的配置中。

它适用于循环策略。

但是，当我关闭其中一个微服务实例功能区时，仍然会向该实例发送请求并将错误返回给客户端。

如何在 ZuulProxy 中启用 healthCheck 功能？

我的zuul配置如下图：

shared.microservice.customer.service1.url=ip1:port1/shared/microservice/customer/

shared.microservice.customer.service2.url=ip2:port2/shared/microservice/customer/

ribbon.eureka.enabled = false

zuul.routes.customer-micro-service.path: /shared/microservice/customer/**

zuul.routes.customer-micro-service.serviceId: customers

customers.ribbon.listOfServers = ip1:port1/shared/microservice/customer/,ip2:port2/shared/microservice/customer/

我的 Main Spring 类具有以下注释：

@EnableZuulProxy
@SpringBootApplication
@ComponentScan(basePackages = { "com.my.gateway"})
public class ZuulProxyApplication

我得到以下异常：
