SpringCloud-Spring Cloud Alibaba Nacos服务注册之消费模块注册(Day11)

我们之前已经创建了cloudalibaba-provider-payment9001，我们仿照这个支付模块创建cloudalibaba-provider-payment9002。目的是为了创建多个提供微服务的实例。

创建消费模块cloudalibaba-consumer-nacos-order9083

更改消费模块的pom

更改消费模块的yml

server:
  port: 9083

spring:
  application:
    name: nacos-order-consumer
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

#消费者将要去访问的微服务名称(注册成功进nacos的微服务提供者)
service-url:
  nacos-user-service: http://nacos-payment-provider

更改消费模块的主启动

package com.gcl.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class OrderMain9083 {

    public static void main(String[] args) {
        SpringApplication.run( OrderMain9083.class , args );
    }

}

更改消费模块的业务代码

package com.gcl.springcloud.config;

import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class LoadBanceCOnfig {

    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }

}

package com.gcl.springcloud.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import javax.annotation.Resource;

@RestController
public class OrderController {

    @Value("${service-url.nacos-user-service}")
    private String baseUrl;

    @Resource
    private RestTemplate restTemplate;


    @GetMapping(value = "/consumer/payment/nacos/{id}")
    public String paymentInfo(@PathVariable("id") Long id)
    {
        return restTemplate.getForObject(baseUrl+"/payment/nacos/"+id,String.class);
    }

}

运行(轮询请求)
