SpringBoot整合 Apollo 入門

基礎概念

  1. 官方文件(官網介紹較為詳細,不再贅述)

https://www.apolloconfig.com/#/zh/design/apollo-introduction

SpringBoot整合

一.官網給予了基礎的Quick Start,可參考學習入門 ,(win平臺啟動可以使用git客戶端執行sh指令碼)

$ sh ./demo.sh start
Windows new JAVA_HOME is: /d/DevProgram/Java/jdk
==== starting service ====
Service logging file is ./service/apollo-service.log
Started [1121]
Waiting for config service startup...

看到Started [1121]即表示成功!
二.這裡給出在springboot工程中如何使用的簡單demo
1.首先參考Quick Start文件,搭建基礎環境,包括 Apollo config應用和資料庫等
2.新建springboot 工程,匯入web依賴和Apollo client依賴

         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">

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>
    <groupId>com.ggq</groupId>
    <artifactId>springboot-apollo</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <!-- web功能起步依賴-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- apollo 客戶端依賴-->
        <dependency>
            <groupId>com.ctrip.framework.apollo</groupId>
            <artifactId>apollo-client</artifactId>
            <version>1.3.0</version>
        </dependency>
    </dependencies>

</project>

2.主啟動類

package com.ggq;

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

import com.ctrip.framework.apollo.spring.annotation.EnableApolloConfig;

@SpringBootApplication
@EnableApolloConfig //此處開啟apollo配置
public class ApolloClientStart {
    public static void main(String[] args) {
        SpringApplication.run(ApolloClientStart.class,args);
    }
}

3.構建基礎配置檔案,指定apollo配置中心地址和應用本身id等

server:
  port: 8081

app:
  id: springboot-apollo
apollo:
  meta: http://127.0.0.1:8080
  bootstrap:
    enabled: true
    eagerLoad:
      enabled: true

4.測試類

package com.ggq.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @Value( "${name}" )
    private String name;

    @RequestMapping("/name")
    public String ReadName() {
        return "我的名字是:"+this.name;
    }

}

訪問http://localhost:8081/name,可以得到我的名字是:張三 ,重新在apollo中配置name值無需重啟,再次請求
http://localhost:8081/name,可得到我的名字是:李四
