阿里云OSS简单上传

1. 引入依赖

    <dependencies>
        <!--阿里云OSS云存储依赖-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alicloud-oss</artifactId>
            <version>2.2.0.RELEASE</version>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2.2.6.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2. 配置信息

spring:
  # 服务名称
  application:
    name: MapleDemoApplication
  # OSS配置
  cloud:
    alicloud:
      oss:
        endpoint: oss-cn-shenzhen.aliyuncs.com
        bucket: lianxi-maple
      access-key: 
      secret-key: 

3. 简单上传控制类
