服務發現：Eureka服務器

如何包括Eureka服務器

要在項目中包含Eureka服務器，請使用組org.springframework.cloud和工件id spring-cloud-starter-eureka-server的啟動器。有關 使用當前的Spring Cloud發布列表設置構建系統的詳細信息，請參閱Spring Cloud項目頁面。

如何運行Eureka服務器

示例eureka服務器;

@SpringBootApplication
@EnableEurekaServer
public class Application {

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

}
 


創建springboot項目 搭建eureka
在。yml配置文件中

server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: false
server:
wait-time-in-ms-when-sync-empty: 5

server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: false
server:
wait-time-in-ms-when-sync-empty: 5
