Java Eureka同伴意识示例不起作用

我在运行Eureka服务器示例以了解对等感知概念时遇到了问题。 我有以下Eureka服务：

package com.micro.eurekaserver;

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

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaServer
public class EurekaServerMicroServiceApplication {

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

application.yml

  port: 8761

  instance:
    hostname: peer1

etc/hosts

当我运行此Eureka服务时，我不断遇到以下异常：

我能够使用单个实例成功运行Eureka服务。我只面临两个问题。github的以下演示示例：[

我在日志中还注意到，tomcat嵌入式服务器是在端口8080上启动的，而不是8761/8762，不知道为什么

请帮助！

尝试从您的Application.java中删除@EnableDiscoveryClient。我的如下所示：

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

@SpringBootApplication
@EnableEurekaServer
public class Application {

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

---

如果

Eureka

仍从8080开始，则很可能您没有通过激活的

Spring

配置文件

每个实例都需要按以下方式启动：

java -Dspring.profiles.active=peer1 target/<artifact>.jar

---

java-Dspring.profiles.active=peer1 target/其中我介绍了在
standalone
和
peerAware
模式下使用
Spring
配置文件运行
Eureka
。在
peerAware
配置文件中，我使用VM参数传递其他
Eureka
实例的位置，因此无需将代码更改为start新实例。它还包括使用
Feign
、
Ribbon
和
restemplate
的负载平衡请求，客户机使用
Jersey
1和
Spring
REST实现。
我也遇到过同样的问题，搜索了很多次，但运气不佳

最后，我只是将概要文件修改为概要文件，它出人意料地发挥了作用：

spring:
  profile: peer1

而不是：

spring:
   profiles: peer1
