场景说明：本次测试是springboot项目，可以链接上ncaos，将对应命名空间下的配置信息读取出俩，然后可以在接口进行返回显示。

0.环境配置

1.代码结构

2.POM配置

<?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><version>2.2.2.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.itheima</groupId><artifactId>demonacostest</artifactId><version>0.0.1-SNAPSHOT</version><name>demonacostest</name><description>demonacostest</description><properties><java.version>8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.28</version></dependency>
<!--        <dependency>-->
<!--            <groupId>org.springframework.cloud</groupId>-->
<!--            <artifactId>spring-cloud-starter-bootstrap</artifactId>-->
<!--            <version>3.0.3</version>-->

3.bootstrap.yml如下，不需要application.yml

spring:application:name: nacos-testcloud:nacos:config:server-addr: 43.162.118.209:8848username: nacospassword: nacosnamespace: f90776be-d19e-41c4-b55f-4cdcae33fa57file-extension: yaml
# 本地配置示例
app:local-config: 这是本地配置

4.配置属性模型

ConfigProperties

package com.itheima.demonacostest.config;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.stereotype.Component;import java.io.Serializable;@Data
@Component
@RefreshScope
@ConfigurationProperties(prefix = "base.config")
public class ConfigProperties implements Serializable {private String appKey;private String appKey2;
}

5.接口如下

package com.itheima.demonacostest.controller;import com.itheima.demonacostest.config.ConfigProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/api/config")
public class ConfigController {@Autowiredprivate ConfigProperties nacosConfigProperties;@RequestMapping(value = "getConfig", method = RequestMethod.GET)public String getConfig() {return nacosConfigProperties.getAppKey();}@RequestMapping(value = "getConfig2", method = RequestMethod.GET)public String getConfig2() {return nacosConfigProperties.getAppKey2();}
}
