Question

在config-server到达Eureka的UP状态后不久，我就间歇地启动Zuul。 Zuul报告说没有可用的configserver应用程序。

在启动Zuul来查询eureka的config-server-1应用程序之前，我已经添加了curl。这证实了eureka肯定具有Zuul报告该应用程序不可用的应用程序。

Zuul配置：

spring:
  cloud:
    circuit:
      breaker:
        enabled: true

eureka:
  client:
    registerWithEureka: true

server:
  port: 8080

zuul:
  ignoredServices: '*'
  routes:
    # Platform Services
    eureka:
      path: /discovery/**
      serviceId: eureka-server-1
      stripPrefix: false
      retryable: true
    some-test:
      path: /some-test/**
      serviceId: some-test
      stripPrefix: true
      retryable: true
    config:
      path: /config/**
      serviceId: config-server-1
      stripPrefix: true
      retryable: true

Eureka查询config-server-1的响应：

  </instance>
</application>

在zuul服务器中记录输出：

[2019-06-27 14:19:21.957][ERROR][o.s.boot.SpringApplication              ] Application run failed
java.lang.IllegalStateException: No instances found of configserver (config-server-1)
        at org.springframework.cloud.config.client.ConfigServerInstanceProvider.getConfigServerInstances(ConfigServerInstanceProvider.java:25)
        at org.springframework.cloud.config.client.DiscoveryClientConfigServiceBootstrapConfiguration.refresh(DiscoveryClientConfigServiceBootstrapConfiguration.java:84)
        at org.springframework.cloud.config.client.DiscoveryClientConfigServiceBootstrapConfiguration.startup(DiscoveryClientConfigServiceBootstrapConfiguration.java:69)

如果config-server-1处于启动状态，则预计zuul服务器将始终成功启动。

我发现间歇性的zuul服务器报告config-server-1应用程序不可用。

Zuul core version: 1.3.1
Eureka core version: 1.9.2
Config server version: 2.0.0.RELEASE

Zuul报告config-server-1应用程序在eureka报告已启动的地方不可用
