服务端

build.gradle配置

dependencies {	compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')	testCompile('org.springframework.boot:spring-boot-starter-test')}dependencyManagement {	imports {		mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"	}}

bootstrap.yml相关配置

server.port: 8761management.port: 8762eureka:  instance:    hostname: localhost  client:    registerWithEureka: false    fetchRegistry: false    serviceUrl:      defaultZone: http://localhost:8761/eureka/

启动代码

package lind.sprindemo.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;@EnableEurekaServer@EnableDiscoveryClient@SpringBootApplicationpublic class EurekaServerApplication {	public static void main(String[] args) {		SpringApplication.run(EurekaServerApplication.class, args);	}}

客户端

向我们配置中心的客户端同时也是eureka的一个客户端，例如一个订单服务，它的配置存储在配置中心，它如果希望公开自己，就需要是eureka的一个客户端。

例子

graph TD A[订单服务]-->B(注册) B-->C(eureka) A-->D(获取配置) D-->E(clientserver)
