springboot集成nacos最重要的是版本的对应。详细版本请参考版本说明
1.主要是引入相对应的版本和依赖包，pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>

2.添加启动注解@EnableDiscoveryClient
package com.menshaojing.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@EnableDiscoveryClient
@SpringBootApplication
public class TestServerApplication {
public static void main(String[] args) {
SpringApplication.run(PenServerApplication.class, args);
}
}
3.配置bootstrap.yml
spring:
application:
name: nacos-server
profiles:
active: dev
cloud:
nacos:
config:
file-extension: yaml
server-addr: 127.0.0.1:8848
extension-configs:
- data-id: application-dev.yml
group: DEFAULT_GROUP
refresh: true
discovery:
server-addr: 127.0.0.1:8848
4. resources排除了需要外置的文件,我们可以通过配置启动参数（vm options）进行引用外置文件进行启动
例如：
-Dspring.cloud.nacos.config.namespace=public
-Dspring.cloud.nacos.discovery.namespace=public
-Dspring.config.location=D:/work/nacos-server/src/main/resources/bootstrap.yml
-Dserver.port=9110
