如何使用eureka的spring cloud网关

Question

我想使用带有eureka的spring cloud网关进行定位服务 我的路线配置：

spring:
  cloud:
    gateway:
      discovery.locator.enabled: true
      routes:
      - id: dicts
        uri: lb://neoflex-dict
        predicates:
           - Path=/dicts/**
      - id: oauth
        uri: lb://auth_server
        predicates:
           - Path=/oauth/**
      - id: catalog
        uri: lb://catalog
        predicates:
          - Path=/catalog/**
      - id: users
        uri: lb://auth_server
        predicates:
          - Path=/users/**
      - id: neoflex-dict-front
        uri: lb://neoflex-dict-front
        predicates:
          - Path=/dicts_front/**

我添加到主类

@Bean
    public DiscoveryClientRouteDefinitionLocator clientRouteDefinitionLocator(DiscoveryClient discoveryClient) {
        return new DiscoveryClientRouteDefinitionLocator(discoveryClient);
    }

我收到错误消息

org.springframework.cloud.gateway.support.NotFoundException: Unable to find instance for localhost
at org.springframework.cloud.gateway.filter.LoadBalancerClientFilter.filter(LoadBalancerClientFilter.java:72) ~[spring-cloud-gateway-core-2.0.0.M9.jar:2.0.0.M9]

中的问题

final ServiceInstance instance = loadBalancer.choose(url.getHost()); 

我无法理解为什么url = http://localhost:8600/oauth/token
