附：Nacos 文档

附：【github】nacos下载地址

ps:直接从github上下载nacos安装包会特别慢，网上的改host办法使用过，没有什么效果，建议使用VPN，或者使用别人已经下载好的；

附：【csdn】nacos-server-1.1.0.tar.gz

tar -zxvf nacos-server-1.1.0.tar.gz  解压
cd nacos
cd bin
sh startup.sh -m standalone 启动

出现下图，表示启动成功。

登录http://192.168.101.16:8848/nacos /index.html，并输入账号密码;均为nacos。出现如下界面；

注：版本对应：

项目结构：

1.模块：alibaba-nacos-discovery-server:

控制层：

package com.lucifer.demo.controller;


import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
/**

@Slf4j
@RestController
public class TestController {

    @GetMapping("/hello/{name}")
    public String hello(@PathVariable(name = "name") String name) {
        log.info("invoked name = " + name);
        return "hello " + name;
    }


}

springboot 启动类：（ps:`@EnableDiscoveryClient` 开启服务注册发现功能）

package com.lucifer.demo;

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

/**
 * @author Lucifer
 */
@EnableDiscoveryClient
@SpringBootApplication
public class AlibabaNacosDiscoveryServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(AlibabaNacosDiscoveryServerApplication.class, args);
    }

}

springboot 配置文件：

spring:
  application:
    name: service-provider
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.101.16:8848

server:
  port: 8001

pom.xml：（主要jar包）

    </dependencies>

启动：

2.模块：alibaba-nacos-discovery-client

1》springboot启动类：同alibaba-nacos-discovery-server 启动类，加上@EnableDiscoveryClient；

2》配置文件：

spring:
  application:
    name: service-consumer
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.101.16:8848

server:
  port: 8080

3》pom.xml同上

控制层：

package com.lucifer.alibabanacosdiscoveryclient.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
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;

/**
 * @author: lucifer
 * @date: 2019/8/6
 * @description:
 */
@EnableDiscoveryClient
@RestController
public class TestController {

    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @Autowired
    private RestTemplate restTemplate;


    @GetMapping(value = "/hello/{str}")
    public String echo(@PathVariable(name = "str") String str) {
        return restTemplate.getForObject("http://service-provider/hello/" + str, String.class);
    }


}
