Nacos Config的配置中心

本文主要是介绍Nacos Config的配置中心，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.创建一个新的文件

2.导入依赖

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.muke</groupId><artifactId>configdemo</artifactId><version>1.0-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.2.RELEASE</version></parent><dependencies><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>2.2.5.RELEASE</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>
</project>

3.创建启动类

package com.muke;import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RefreshScope
public class TestController {@Value("${testStr}")private String  testStr;@GetMapping("/test")public String test(){return testStr;}
}

4.在Nacos中新增配置

记得勾选yaml

5.调用配置

使用bootstrap.yaml

spring:application:name: configdemocloud:nacos:config:server-addr: localhost:8848file-extension: yaml

6.启动

7.测试

8.增加动态配置注解@RefreshScope

/*** @author ziya* @date 2021/3/2 12:19 上午*/
@RestController
@RefreshScope
public class TestController {@Value("${testStr}")private String  testStr;@GetMapping("/test")public String test(){return testStr;}
}

成功
