1.生产者注册

1.1 添加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- 添加了nacos服务和注册依赖 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

1.2 启动类

1.3 配置application.yml文件

1.4设置Controller层接收请求

1.5 页面效果

2.消费者调用

消费端调用提供端
nacos的关系

2.1添加依赖

2.2 配置application.yml文件

server:
  port: 8090
spring:
  application:
    name: sca-concumer
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

2.3 创建启动类

2.4 创建Controller层

package com.jt.concumer.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
/*定义服务消费端 在这层的方法中通过一个对象实现对远端服务sca-provider的调用*/
@RestController
public class ConcumerController {
    /*通过此对象调用远端服务*/
    @Autowired
    private RestTemplate restTemplate;
    /*读取配置文件中的属性值然后赋值给appName*/
    @Value("${spring.application.name}")
    private String appName;

    @GetMapping("/concumer/doRestEcho1")
    public String doRestEcho1(){
        //1.定义要调用的远端服务的url
        String url="http://localhost:8081/provider/echo/"+appName;
        //2.基于restTemplate的对象中的方法进行服务调用
        return restTemplate.getForObject(url, String.class);
    }

}
