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:

3. 创建服务提供者

3.2. yml配置文件

server:
  port: 9002
spring:
  application:
    name: nacos-payment-provider
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848 #配置nacos服务地址
# 暴露端点

3.3 主启动

package biienu;

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


@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain9002 {


    public static void main(String[] args) {

        SpringApplication.run(PaymentMain9002.class,args);
    }
}

3.4. 业务类

package biienu.controller;

import lombok.extern.slf4j.Slf4j;
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;

@RestController
@Slf4j
public class PaymentController {

    @Value("${server.port}")
    private String serverPort;

    @GetMapping(value = "/payment/nacos/{id}")
    public String getPayment(@PathVariable(value = "id") Integer id){
        return "nacos registry, serverPort : " + serverPort +"t id" + id;
    }
}

4. 创建服务消费者

4.2 yml文件

server:
  port: 83
spring:
  application:
    name: cloud-consumer-nacos
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
management:
  endpoints:
    web:
      exposure:
        include: '*'

#服务提供者地址
service:
  service-url:  "http://nacos-payment-provider/payment/nacos/"

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:
