application.yml

server:  
  port: ${PORT:8761}
    
eureka:  
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
  server:
    enableSelfPreservation: true
    renewalPercentThreshold: 0.1

注: 可以使用application.properties, 其格式为

server.port=8761

eureka.instance.hostname=localhost

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

eureka.server.enableSelfPreservation=true
eureka.server.renewalPercentThreshold=0.1

EurekaserverApplication.java

package com.rockbb.springcloud.demo.eurekaserver;

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

@EnableEurekaServer
@SpringBootApplication
public class EurekaserverApplication {

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

建立运行配置: Run/Debug Configurationst添加Application, 使用main class:  com.rockbb.springcloud.demo.eurekaserver.EurekaserverApplication 即可.

Update: pom可以不使用spring boot作为parent, 这时候需要改动的有两处

1. 在 dependencyManagement>dependencies添加dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.0.2.RELEASE</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

2. 在build>plugins下添加plugin (如果build时报错target版本不对, 则添加这个, 如果没报错可以不添加)

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <encoding>${project.build.sourceEncoding}</encoding>
    </configuration>
</plugin>
