  简而言之,nacos与eureka的不同之处有三:后台老板、部署方式、功能。nacos是阿里的,eureka是奈飞的;nacos有自己的安装包,需要独立部署,eureka仅作为一个服务组件,引入jar包即可;nacos=eureka+config,它既是注册中心,也是配置中心。

  如何使用nacos?先下载安装包(下载地址https://github.com/alibaba/nacos/releases),打开下载页 -> 点击目前最新版本1.1.3跳到下载页 -> 点击压缩包 -> 下载到本地(E盘download目录)后解压 -> 通过命令行启动nacos:

C:\Users\wulf>e:
E:\
>cd download\nacos\bin
E:\download\nacos\bin
>startup.cmd -m standalone

  我们通过localhost:8848/nacos可以访问到它,默认用户名密码都是nacos:

  我们创建个项目来注册到这个nacos,三板斧又来了:

  1、pom引入spring boot、spring cloud、spring cloud alibaba和nacos:


org.springframework.boot
spring-boot-starter-parent
2.1.7.RELEASE



org.springframework.cloud
spring-cloud-dependencies
Greenwich.SR2
pom
import


org.springframework.cloud
spring-cloud-alibaba-dependencies
0.9.0.RELEASE
pom
import


org.springframework.cloud
spring-cloud-starter-alibaba-nacos-discovery



  2、application:

#端口
server.port
=8282
#应用名
spring.application.name
=lxytrans-provider
#注册中心
spring.cloud.nacos.discovery.server
-addr=localhost:8848

  3、启动类加注解:

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@EnableDiscoveryClient
@SpringBootApplication
public class TransProviderApplication {
public static void main(String[] args) {
SpringApplication.run(TransProviderApplication.
class, args);
}
@Slf4j
@RestController
static class TestController {
@GetMapping(
"/hello")
public String hello() {
return "hello";
}
@GetMapping(
"/hey")
public String hey() throws InterruptedException {
Thread.sleep(
2000);
return "hey";
}
}
}

  跑起来后我们看下nacos控制台实例:
