spring cloud 使用nacos配置中心

創建NACOS配置

• Data ID: 配置文件名，格式爲 <spring.cloud.nacos.config.prefix>[-spring.profiles.active].<spring.cloud.nacos.config.file-extension>
• Group: 分組，<spring.cloud.nacos.config.group>
  

依賴

<dependencies>
	<dependency>
	    <groupId>com.alibaba.cloud</groupId>
	    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
	</dependency>
</dependencies>
<dependencyManagement>

            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

配置

bootstrap.yml

spring:
  application:
    name: sample-nacos1
  profiles:
    active: dev
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        # 默認前綴爲${spring.application.name}
        prefix: ${spring.application.name}
        # 默認配置文件擴展名爲properties
        file-extension: yml
        # 默認名空間爲public
        namespace: public
        # 默認組爲DEFAULT_GROUP
        group: SAMPLE_NACOS

效果

日誌顯示找到了配置文件

b.c.PropertySourceBootstrapConfiguration : Located property source: [BootstrapPropertySource {name='bootstrapProperties-sample-nacos1-dev.yml,SAMPLE_NACOS'}, BootstrapPropertySource {name='bootstrapProperties-sample-nacos1.yml,SAMPLE_NACOS'}, BootstrapPropertySource {name='bootstrapProperties-sample-nacos1,SAMPLE_NACOS'}]

注意

• spring.cloud.nacos.config.namespace配置如果使用自定義命名空間，需要填入命名空間ID而非名稱
• 啓動報錯org.yaml.snakeyaml.error.YAMLException: java.nio.charset.MalformedInputException: Input length = 1
  可能出現在不同環境部署啓動報此錯誤情況，是JVM默認字符集問題導致，設置啓動JVM參數 -Dfile.encoding=UTF-8即可
