本文档详细介绍了如何在eclipse环境中启动两个不同的EurekaClient实例。首先，创建并配置EurekaServer，然后创建一个新的Spring Boot项目，添加@EnableEurekaClient注解。在application.yml和application-two.yml中分别设置不同的端口和服务ID，确保每个实例的独特性。通过依次运行EurekaServer和两个EurekaClient的不同配置，成功实现了在eclipse中运行两个EurekaClient实例。

1、创建EurekaService

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class App {

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

application.yml

server:
port: 8761

eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

spring:
application:
name: eurka-server

2、新建spring boot项目添加@EnableEurekaClient

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class App {

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

}

application.yml

server:
port: 8762

spring:
application:
name: spring-cloud-front
eureka:
instance:
instance-id: spring-cloud-front1 #id一定要与 application-two.yml 中id不同，不然2个实例会被覆盖
appname: ${spring.application.name}
client:
service-url:
defaultZone: http://localhost:8761/eureka/

application-two.yml

server:
port: 8765

spring:
application:
name: spring-cloud-front
eureka:
instance:
instance-id: spring-cloud-front2
appname: ${spring.application.name}
client:
service-url:
defaultZone: http://127.0.0.1:8761/eureka/
