SpringCloud Alibaba Nacos服务注册中心与服务提供者
最近由于Netfix公司停止维护SpringCloud中相关的组件，造成了一些讨论，但是此时正好阿里发布了阿里维护的一些列SpringCloud的组件，比如说我本篇要讲的Nacos,此处先提供nacos中文官网的地址
安装Nacos
可以使用Maven或者手动下载安装启动的方式。此处不做过多赘述，详细请看
https://nacos.io/zh-cn/docs/quick-start.html
构建SpringCloud Alibaba项目
首先我们先构建一个文件夹，并新建一个统一依赖的项目。
项目的pom文件
4.0.0
org.springframework.boot
spring-boot-starter-parent
2.0.6.RELEASE
com.funtl
hello-spring-cloud-alibaba-dependencies

然后就构建一个服务提供者的项目。项目的pom如下
4.0.0
com.funtl
hello-spring-cloud-alibaba-dependencies
1.0.0-SNAPSHOT
../hello-spring-cloud-alibaba-dependencies/pom.xml
hello-spring-cloud-alibaba-nacos-provider
jar
hello-spring-cloud-alibaba-nacos-provider

org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-actuator
org.springframework.boot
spring-boot-starter-test
test
org.springframework.cloud
spring-cloud-starter-alibaba-nacos-discovery
org.springframework.boot
spring-boot-maven-plugin
com.funtl.hello.spring.cloud.alibaba.nacos.provider.NacosProviderApplication
紧接着我们在application.yml中配置相关信息
spring:
application:
name: nacos-provider
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
server:
port: 8081
management:
endpoints:
web:
exposure:
include: "*"
添加与原生SpringCloud一样的服务提供者注解
package com.funtl.hello.spring.cloud.alibaba.nacos.provider;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@EnableDiscoveryClient
public class NacosProviderApplication {
public static void main(String[] args) {
SpringApplication.run(NacosProviderApplication.class, args);
}
@RestController
public class EchoController {
@GetMapping(value = "/echo/{message}")
public String echo(@PathVariable String message) {
return "Hello Nacos Discovery " + message;
}
}
}
启动服务提供者项目之前启动nacos
然后启动服务提供者项目
观察到服务提供者已经被注册到nacos
使用http://localhost:8848/nacos登录nacos项目的后台。使用用户名/密码：nacos/nacos登录。在服务列表中可以看到我们注册的服务
