Spring Cloud 入门程序，集成Eureka

Spring Cloud是一系列框架的有序集合。它利用Spring Boot的开发便利性巧妙地简化了分布式系统基础设施的开发，如服务发现注册、配置中心、消息总线、负载均衡、断路器、数据监控等，都可以用Spring Boot的开发风格做到一键启动和部署。Spring Cloud并没有重复制造轮子，它只是将目前各家公司开发的比较成熟、经得起实际考验的服务框架组合起来，通过Spring Boot风格进行再封装屏蔽掉了复杂的配置和实现原理，最终给开发者留出了一套简单易懂、易部署和易维护的分布式系统开发工具包。

配置application.yml：

server:

port: 8761



eureka:

instance:

hostname: localhost

client:

registerWithEureka: false

fetchRegistry: false

serviceUrl:

defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

加入@EnableEurekaServer注解启动Eureka

@SpringBootApplication

@EnableEurekaServer

public class EurekaserverApplication {



public static void main(String[] args) {

SpringApplication.run(EurekaserverApplication.class, args);

}

}

启动程序：访问http://localhost:8761/
