搭建Eureka服务发现中心

项目源码：https://gitee.com/lwydyby/springcloud-adplatform

maven搭建有两种方式：

（1）使用idea直接搭建spring-io的springcloud项目

（2）直接创建普通maven项目，自己配置pom.xml （该文章使用这种方式）

pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    		</dependency>
    	</dependencies>
    
    	<build>
    		<plugins>
    			<plugin>

    				<executions>
    					<execution>
    						<phase>package</phase>
    						<goals>
    							<goal>build</goal>
    						</goals>
    					</execution>
    				</executions>
    				<configuration>
    					<imageName>gameley/eureka</imageName>
    					<dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
    					<resources>
    						<resource>
    							<targetPath>/</targetPath>
    							<directory>${project.build.directory}</directory>
    							<include>${project.build.finalName}.jar</include>
    						</resource>
    					</resources>
    				</configuration>
    			</plugin>
    		</plugins>
    
    	</build>
    
    
    </project>

本项目使用了jetty替代tomcat，docker-maven-plugin为后边搭建docker镜像使用（暂时可以忽略），spring-boot-starter-actuator为更详细的监控引入

创建EurekaServerApplication启动类：

package com.gameley;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class EurekaServerApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(EurekaServerApplication.class, args);
    	}
    }
    
    
     
    配置文件 application.yml：
     
     
     server:
      port: 8761
    
    eureka:
      instance:
        hostname: localhost
      client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
