【springcloudalibaba】——聊一聊，微服务是如何嗨皮的注入到consul中的（zcw-demo）【十七】

前言

本篇博客主要是演示，我们的微服务（服务提供者）是如何注入到我们consul中的，通过demo的练习，除了提高自己的技术水平之外，也希望能帮助需要帮助的人，(✪ω✪)

服务提供者

• 创建项目
  
  
  
  
• 修改POM文件

</project>

• 创建YML文件

# consul服务端口号
server:
  port: 8006

spring:
  application:
    name: consul-provider-payment

# consul注册中心地址
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
        #hostname
        sevice-name: ${spring.application.name}

• 创建启动类

package com.zcw.springclou;

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

/**
 * @ClassName : PayMentApplication8006
 * @Description :
 * @Author : Zhaocunwei
 * @Date: 2020-05-14 14:57
 */
@SpringBootApplication
@EnableDiscoveryClient
public class PayMentApplication8006 {
    public static void main(String[] args) {
        SpringApplication.run(PayMentApplication8006.class,args);
    }
}

• 创建controller层

package com.zcw.springclou.controller;

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.UUID;

/**
 * @ClassName : PaymentController
 * @Description :
 * @Author : Zhaocunwei
 * @Date: 2020-05-14 15:00
 */
@RestController
@Slf4j
public class PaymentController {
    @Value("${server.port}")
    private String serverPort;

    @RequestMapping(value = "/payment/consul")
    public String paymentConsul(){
        return "springcloud with consul"+serverPort+"\t"+ UUID.randomUUID().toString();
    }
}

• 验证测试
