nacos服务注册与发现
注意:
本文基于springboot2.6.3v,springcloud2021.0.1v,springcloudalibaba2021.0.1.0v,nacos1.4.3v
各版本选择关系如下:
1.nacos下载与启动
nacos下载地址
https://github.com/alibaba/nacos/releases/tag/1.4.3
- 解压安装包
nacos-server-1.4.3.zip, 进入bin目录,
-
startup用于启动服务
-
shutdown关闭服务
启动时:startup.cmd -m standalone用于单机启动(非集群)启动服务后浏览器url地址栏输入http://192.168.72.1:8848/nacos/index.html进入nacos图形管理界面,用户名和密码都是
nacos
出现上图说明nacos服务启动成功
项目结构:
2. 创建服务方和消费方
1. 创建服务方和消费方之前先创建一个父工程，用于统一管理依赖
2. 父工程pom结构:

4.2 yml文件

discovery:
server-addr: localhost:8848
management:
endpoints:

4.3 主启动
package com.biienu;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableDiscoveryClient
public class ConsumerNacosMain83 {
public static void main(String[] args) {
SpringApplication.run(ConsumerNacosMain83.class, args);
}
}
4.4 业务类
配置类:
package com.biienu.conf;
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 BeanConf {
@Bean
@LoadBalanced
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
controller:
package com.biienu.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.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class ConsumerController {
@Autowired
private RestTemplate restTemplate;
@Value("${service.service-url}")
private String serviceUrl;
@GetMapping("/consumer/payment/nacos/{id}")
public String consumerOrder(@PathVariable(value = "id") Integer id){
return restTemplate.getForObject(serviceUrl + id, String.class);
}
}
3. 测试
1. 启动nacos服务
2. 启动服务提供者服务(9001, 9002)
3. 启动消费者服务(83)
4. 浏览器地址栏输入http://localhost:83/consumer/payment/nacos/1 进行多次刷新测试。
4. 注意点
1. 由于spring-cloud-starter-alibaba-nacos-discovery 2021.0.1.0版本, 没有集成ribbon 所以要自己加上负载均衡依赖spring-cloud-starter-loadbalancer
如果没有加上这个依赖就会报这样的错误:
