springCloud-netflix-Eureka的注册与发现(服务提供者)

构建服务提供者

创建服务提供者的前提你要有服务的注册中心,详情参考Eureka注册中心

打开IDEA —>File---->New---->Project

点击下一步

然后再点击下一步，再点击finsh就行了.

创建后的pom文件如下:

注意将eureka服务jar改为

修改程序启动类

@SpringBootApplication
@EnableEurekaClient //开启eureka客户端注解
@RestController
public class EurekaProvider1Application {

    public static void main(String[] args) {
        SpringApplication.run(EurekaProvider1Application.class, args);
    }

    @Value("${server.port}")
    private String port;
    @GetMapping(value = "/hi")
    public String home(@RequestParam("name") String name){
        return "hi"+name+",i am from port:"+port;
    }
}

修改application.yaml全局配置文件

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8888/eureka/
server:
  port: 8889

spring:
  application:
    name: service-hi

启动项目后,在访问http://localhost:8888/ 发现服务以及注册eureka的注册中心中，端口为8889
