Previous article We explain the basic preparation work, and how to integrate SpringBoot with Nacos as a registration center. Today we continue to play NACOS as a configuration center. This article is based on two articles. Subsequent, some pre-prepared work will not be more detailed, and the classmates who do not know can first view the following article content.
Java SpringCloud Series (6) - NACOS Single Edition / Cluster Edition and Precautions under Linux
Java SpringCloud Series (7) - SpringBoot2.1.x Integrated NACOS as a Register Correspondence Code Description

First, NACOS configuration center integration

Step 1: Add dependence

	// https://mvnrepository.com/artifact/com.alibaba.cloud/spring-cloud-starter-alibaba-nacos-config
	implementation group: 'com.alibaba.cloud', name: 'spring-cloud-starter-alibaba-nacos-config', version: '2.1.2.RELEASE'

Step 2: Add a corresponding configuration in the bootstrap.yml configuration file, the code meaning has a correspondence in the code, please read it yourself.

# ================================= Basic configuration ======================================================================================================================================================================================================= =================================================================================================================================================================================
server:
  port: 7165
spring:
  application:
    name: beyondli-nacos-demo
  # Can use this parameter to perform environmental distinguishing (file name rules for Spring.Application.name-profiles.active.file-extension)
  #profiles:
  #  active: dev
  cloud:
    nacos:
      discovery:
        server-addr: ip:Port
      config:
        server-addr: ip:Port
        file-extension: yaml
        # Default value for default_group Use this parameter to use this parameter to distinguish (file name rules for Spring.Application.name-profiles.active.file-extension)
        group: BEYONDLI_NACOS_DEV

Step 3: Enter NACOS to create a corresponding configuration file based on the code in the code

Step 4: Writing Getting Configuration Center Value Code

Second, dynamic modification configuration center content

Step 1: Add @refreshscope on the required class

Step 2: Modify the configuration center value for testing

Step 3: Refresh the interface, return value automatic changes

All right. The above is all of our articles.
