同一应用程序中的配置服务器和eureka服务器:尝试连接到localhost:8761

Question

我有一个spring-boot应用程序,我用它来设置spring cloud config server和eureka server开发和测试环境.奇怪的是,应用程序总是尝试连接localhost:8761,即使我已eureka.client.registerWithEureka设置为false.

我该如何停用此功能？

错误:

我唯一的课程看起来像这样:

@EnableEurekaServer
@EnableConfigServer
@SpringBootApplication
public class MyApplication {
  public static void main(String[] args) {
    SpringApplication.run(MyApplication.class, args);
  }
}

的application.yml:

server:
  port: 8888

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
  server:
    waitTimeInMsWhenSyncEmpty: 0
    renewal-percent-threshold: 0.49

security:
  basic:
    enabled: true
  user:
    password: mypassword


spring:
  jmx:
    default-domain: ${spring.application.name}
  cloud:
    config:
      server:
        git:
          uri: https://example.com/myrepo.git
          username: username
          password: password
          clone-on-start: true
          search-paths: '{application},{application}/{profile}'

endpoints:
  jmx:
    domain: ${spring.application.name}
    unique-names: true

在bootstrap.yml我只有应用程序名称集.

版本:

spring-cloud-netflix-eureka : 1.1.6, spring-cloud-config-server:1.1.3

Answer 1

您可以尝试更改您的配置,如下所示

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    service-url:
      defaultZone: http://localhost:8888/eureka

你指定server.port: 8888.所以你的eureka运行在8888端口上.但是您没有为eureka指定任何se​​rvice-url.所以我认为您的eureka服务器正在尝试复制到localhost:8761,因为它是默认的,并且您没有为eureka指定service-url.

Answer 2

请为您的 Eureka 服务器使用 8761 端口，如下所示。

server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

这里我们配置了一个应用程序端口——8761 是 Eureka 服务器的默认端口。我们告诉内置的 Eureka 客户端不要注册“自身”，因为我们的应用程序应该充当服务器。

对我来说，以下属性对我有用。

eureka.client.registerWithEureka= false
eureka.client.fetchRegistry= false
eureka.server.maxThreadsForPeerReplication=0
