Spring Cloud Eureka Server例子程序

Spring-Cloud-Eureka-Server 及Client 例子程序

参考源代码:https://github.com/spring-cloud-samples/eureka

能够启动成功，可是不能打包，缘由也不太清楚。

启动后访问 http://localhost:8761/ 能够看到启动了哪些实例

实际看来 通常并不须要对 EurekaServer作不少的定制。
彻底能够使用官方已经打包好的EurekaServer。

例子程序中包含的内容也很是少。

对于maven项目
主要就包含
1.入口程序(包含main方法)
2.pom文件(jar包依赖 如今没这玩意真不行)
3.配置文件

注意实际上要添加以下依赖应用才能跑的起来，不然会抛ch.qos.logback相关的一些类找不到。这也是瞎碰碰上找到的。

<dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>1.1.3</version>
        </dependency>

启动后发现eureka页面上有一些红色提示(暂未找到解决办法)

EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.

Client例子程序

启动Client例子程序 就能够从Eureka的页面中看到对应的实例名称了 即注册成功

@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableEurekaClient
@RestController
public class Application {

    @RequestMapping("/")
    public String home() {
        return "Hello world";
    }

    public static void main(String[] args) {
        new SpringApplicationBuilder(Application.class).web(true).run(args);
    }

}

配置文件
application.yml

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

pom

重点注意: 与Server的区别主要是 spring-cloud-starter-eureka
