在 Zuul 中使用 Hystrix Stream 和 Eureka First 查找 Config 服务器

Question

我正在使用 spring cloud Brixton.M4 和 spring boot 1.3.1

我有

的 zuul 服务器

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-netflix-hystrix-stream</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
    </dependency>

我首先使用 Eureka 来查找配置服务器，因此 bootstrap 看起来像

spring:
 profiles: dev 
 cloud:
   config:
     fail-fast: true
     discovery:
       enabled: true
       serviceId: config-server

zuul 注册了两次，首先是 UP 状态，然后是 STARTING

2016-01-18 14:47:27.209  INFO 2808 --- [           main] c.w.i.edgeserver.EdgeServerApplication   : Started EdgeServerApplication in 21.651 seconds (JVM running for 22.232)

2016-01-18 14:48:06.230  INFO 2808 --- [nfoReplicator-0] com.netflix.discovery.DiscoveryClient    : DiscoveryClient_EDGE-SERVER/192.168.17.178:edge-server:8003: registering service...
2016-01-18 14:48:06.238  INFO 2808 --- [nfoReplicator-0] com.netflix.discovery.DiscoveryClient    : DiscoveryClient_EDGE-SERVER/192.168.17.178:edge-server:8003 - registration status: 204

如果我通过设置

移除对配置服务器的依赖

spring:
 profiles: dev 
 cloud:
   config:
     fail-fast: false
     discovery:
       enabled: false
       serviceId: config-server

一切正常。

Answer 1

我认为这很正常（bootstrap阶段必须注册以获取配置服务器位置，然后注销才能让主应用程序再次注册）。您可能会发现在应用程序完全启动后它会恢复到 UP。
