Spring Cloud - 服務發現、注冊、調用

• Spring Cloud - 服務發現、注冊、調用（一）(eureka server)
• Spring Cloud - 服務發現、注冊、調用（二）(eureka client(provider))
• Spring Cloud - 服務發現、注冊、調用（三）(eureka client(consumer))

eureka server

用于服務注冊、發現

建立springboot項目，增加spring-cloud-starter-eureka-server起步依賴：

啟動代碼中增加@EnableEurekaServer

@SpringBootApplication
@EnableEurekaServer
public class SpringbootDemoEurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootDemoEurekaServerApplication.class, args);
    }
}

application.properties(yml請注意縮進)

server.port=1111

eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka

然后樂呵的啟動就可以了：
