【spring cloud】Nacos 測試 config及discovery

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

       
        
            org.springframework.cloud
            spring-cloud-starter-alibaba-nacos-config
            0.9.0.RELEASE
        
        
        
            org.springframework.cloud
            spring-cloud-starter-alibaba-nacos-discovery
            0.9.0.RELEASE
        
        
            org.springframework.boot
            spring-boot-actuator
            2.1.6.RELEASE
        

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
