//3.配置 文件

spring.application.name=spc-service-order
server.port=3001

eureka.client.service-url.defaultZone=http://localhost:1000/eureka/

eureka.instance.preferIpAddress=true
eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port}

//4.启动类

package com.spc.service.order.spc_service_order;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@EnableEurekaClient
@RestController
public class OrderApp {

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

    @Value("${server.port}")
    private String port;
    
    @RequestMapping("/queryOrderStatusById")
    public String queryOrderStatusById(@RequestParam String orderId) {
        return "订单:"+orderId+",OrderStatus:已支付,调用端口:" +port;
    }

}

//运行结果
