Netflix eureka 客户端微服务未向 eureka 服务器注册

Question

我正在尝试向 eureka 服务器注册我的微服务。但它显示浏览器中没有可用的实例。我在控制台中没有收到任何错误。请帮我解决这个问题。

我已经通过搜索 google 尝试了多个选项。尽管如此，我还是无法解决问题。

微服务application.properties

  spring.application.name=jecreations-core
  eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
  eureka.client.register-with-eureka=true

客户端主class

 @EnableEurekaClient
 @SpringBootApplication
 @EnableConfigurationProperties(ImageProperties.class)
 public class JecreationsApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
    SpringApplication.run(JecreationsApplication.class, args);
}
 }

尤里卡服务器application.properties

   eureka.client.register-with-eureka=false
   eureka.client.fetch-registry=false
   server.port=8761
   spring.application.name=DiscoveryServer

尤里卡服务器主class。

 @SpringBootApplication
 @EnableEurekaServer
 public class JeeurekaApplication extends SpringBootServletInitializer{

public static void main(String[] args) {
    SpringApplication.run(JeeurekaApplication.class, args);
}

}

Answer 1

您需要用

注释 eureka 服务器 main class

@SpringBootApplication
@EnableEurekaServer
@EnableDiscoveryClient

public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

此外，您需要在客户的主要 class 中添加注释：

@SpringBootApplication
@EnableDiscoveryClient
public class MicroApplication {

    public static void main(String[] args) {
        SpringApplication.run(MicroApplication.class, args);
    }
}

你需要在eureka客户端的application.yml中进行如下配置：

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

在 Eureka Server application.yml 文件中我有这样的配置：

info:
  component: Eureka Server

server: 
  port: 8761


eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
  server:
    enable-self-preservation: false
    waitTimeInMsWhenSyncEmpty: 0
  instance:
    hostname: localhost
    lease-expiration-duration-in-seconds: 15
    lease-renewal-interval-in-seconds: 5

Answer 2

这样试试

尤里卡服务器配置

eureka.client.registerWithEureka= false
eureka.client.serviceUrl.defaultZone= ${EUREKA_URI:http://localhost:8761/eureka}

eureka 客户端配置

eureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka
eureka.instance.preferIpAddress= true

问题依旧，请关注我的repo https://github.com/vimaleshJeyavelmani/spring-boot-micros

谢谢，

Answer 3

问题出在 eureka 客户端的依赖性上。我给了这个依赖

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-netflix-eureka-client</artifactId>
    </dependency>

而不是

  <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>

感谢您的回复。
