检查实验 spring cloud nacos nacos-server-2.3.0

1.概要

1.1 目标

就是做一个简单服务发现

1.2 要点

1.2.1 引入spring cloud 和spring alibaba的坐标

		
			
				org.springframework.cloud
				spring-cloud-dependencies
				${spring-cloud.version}
				pom
				import
			
			
				com.alibaba.cloud
				spring-cloud-alibaba-dependencies
				2022.0.0.0-RC2
				pom
				import
			
		
	

 1.2.2 导入web 和服务发现的坐标，配置管理的可不导入，目前不关心

    
        org.springframework.boot
        spring-boot-starter-web
    
    
        com.alibaba.cloud
        spring-cloud-starter-alibaba-nacos-discovery
    
    
    
        com.alibaba.cloud
        spring-cloud-starter-alibaba-nacos-config
    

 1.2.3 配置服务名称，没服务名称无法管理服务

spring:
  application:
    name: server3
  cloud:
    nacos:
      config:
        import-check:
          enabled: false

1.2.4  启动spring boot

@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class);
        System.out.println("Hello world!");
    }
}

1.3 技术关键词

• spring-cloud-dependencies 依赖
• spring-cloud-alibaba-dependencies 依赖
• spring-boot-starter-web 依赖
• spring-cloud-starter-alibaba-nacos-discovery 服务注册和发现
• @SpringBootApplication 启动扫描配置
• SpringApplication.run(Main.class); 启动

spring:
  application:
    name: server3
  cloud:
    nacos:
      config:
        import-check:
          enabled: false

2.2.3 主函数

 

package com.xjc.springcloundtest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class);
        System.out.println("Hello world!");
    }
}
