【spring cloud】Nacos 測試 config及di

使用了 https://nacos.io/zh-cn/docs/quick-start-docker.html
中的stondalon啟動nacos

docker-compose -f example/standalone-derby.yaml up

啟動完在瀏覽器上執行 http://127.0.0.1:8848/nacos/

Nacos Login
輸入帳號nacos/密碼nacos,後
Dashboard

Configuration增加一個服務的設定

Data ID: test-provider.yaml
Group: DEFAULT_GROUP
Configuration Content:  server:
                            port: 8888

Add Config

在spring boot的pom.xml設定以下depenency, 版號不可乎略

       <!--nacos-config-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>0.9.0.RELEASE</version><!--必需設定版本號-->
        </dependency>
        <!--nacos-discovery-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>0.9.0.RELEASE</version><!--必需設定版本號-->
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-actuator</artifactId>
            <version>2.1.6.RELEASE</version><!--必需設定版本號-->
        </dependency>

在spring boot的resource增加bootstrap.yml,

spring:
  application:
    name: test-provider
  cloud:  
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      config: # 以下只能增加在bootstrap.yml中
        server-addr: 127.0.0.1:8848
        file-extension: yaml
        prefix: test-provider

在啟動入口增加@EnableDiscoveryClient

package com.leon456.testprovider;

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

@SpringBootApplication
@EnableDiscoveryClient
public class TestProviderApplication {

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

}

啟動後在console上看到port為nacos上設定的8888,非預設的8080
