SpringCloud Alibaba使用Nacos配置中心

SpringCloud Alibaba使用 bootstrap 时需要事先配置 SpringCloud 中的 bootstrap 依赖，这里直接引入 SpringCloud 作为统一版本控制，以下同时引入SpringCloud 和 SpringCloud Alibaba

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${springcloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${springcloud.alibaba.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

配置版本号

    <properties>
        <springcloud.version>2021.0.2</springcloud.version>
        <springcloud.alibaba.version>2021.0.1.0</springcloud.alibaba.version>
    </properties>

最后引入依赖，版本更新后需要引入 bootstrap 依赖才能正常使用

    <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
        </dependency>
    </dependencies>

这里的 bootstrap 配置文件以yml格式为例

spring:
  application:
    name: GULIMALL-COUPON
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        namespace: c16c6635-0e44-4ba4-a2ce-4d3776d84e2c
        prefix: gulimall-coupon
        file-extension: yml
        group: dev
        extension-configs:
          - data-id: datasource.yml
            group: dev
            refresh: true
          - data-id: mybatis.yml
            group: dev
            refresh: true
          - data-id: other.yml
            group: dev
            refresh: true
