Zuul服务器运行应用程序

Question

系统提示出现无法启动服务器时无法连接的错误。我想知道为什么它试图寻找192.168.100.16而不是使用localhost。

我试着运行应用程序使用-Djava.net.preferIPv4Stack = true，但这也没有工作。

application.yml

server: 
    port: 9090 

# remove that settings in production 
management.security.enabled: false 

eureka: 
    client: 
    serviceUrl: 
     defaultZone: http://127.0.0.1:8761/eureka/ 

zuul: 
    #Service will be mapped under the /api URI 
    prefix: /api 
# Uncomment to disable auto-registering all services read from Eureka 
# ignoredServices: '*' 
    routes: 
    test: 
     path: /redirect/** 
     url: http://google.com 
    customer-by-address: 
     path: /customer-by-address/** 
     url: http://localhost:9098 
    customer-by-service: 
     path: /customer-by-service/** 
     serviceId: CUSTOMER-SERVICE 
    static: 
     path: /static/** 

spring: 
    application: 
    name: zuul-server

我有这样的错误

2017-09-05 10:49:35.310 WARN 3671 --- [nfoReplicator-0] c.n.d.s.t.d.RetryableEurekaHttpClient : Request execution failed with message: java.net.ConnectException: Connection refused (Connection refused)

Answer 1

Zuul试图与尤里卡沟通，获取列表的在路由请求时使用的服务。但是，netstat输出不会显示任何在端口8761上侦听的进程，这是您的配置表明Eureka应该在的端口。

Answer 2

正如Faron所说，您的Zuul实例正尝试连接到一台尤里卡服务器。 您可以从您的application.yml删除此

eureka: 
    client: 
    serviceUrl: 
     defaultZone: http://127.0.0.1:8761/eureka/ 

或启动尤里卡（特别是因为你有一个serviceId部分航线）
