1、解決問題

可以直接使用nacos來生成對(duì)應(yīng)的配置文件，進(jìn)行一些自定義的配置

2、創(chuàng)建項(xiàng)目

• pom.xml文件

<?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">

        </dependency>

            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <!--  web組件      -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>

    </dependencies>

</project>

• bootstrap.yml

## 服務(wù)端口
server:
  port: 8000
spring:
  application:
    name: nacos-config-client
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
      config:
        server-addr: localhost:8848
        file-extension: yaml
  profiles:
    active: test

• main 服務(wù)啟動(dòng)類

package com.wyh;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class NacosConfig {

    public static void main(String[] args) {
        SpringApplication.run(NacosConfig.class, args);
    }
    
}

• 讀取配置信息

package com.wyh.controller;

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 ConfigController {

    @Value("${info}")
    private String configInfo;

    /**
     * 需要在 nacos 上創(chuàng)建對(duì)應(yīng)的 info 信息
     *
     * @return 配置
     */
    @GetMapping("/config/version")
    public String getConfigInfo() {
        return configInfo;
    }

}

3、實(shí)踐

自定義配置.png

啟動(dòng)nacos-config項(xiàng)目，訪問"/config/version"接口，就可以獲取配置信息
