springcloud~Eureka实例搭建

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: 8761
management.port: 8762

eureka:
  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
@SpringBootApplication
public 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)
