依赖添加

在Maven的pom.xml文件中添加OSS的依赖：

1.  
   <!--阿里云OSS-->
2.  
   <dependency>
3.  
   <groupId>com.aliyun.oss</groupId>
4.  
   <artifactId>aliyun-sdk-oss</artifactId>
5.  
   <version>2.8.3</version>
6.  
   </dependency>

在application.yml中添加配置信息：

1.  
   #OSS配置
2.  
   oss:
3.  
   #带有地域节点的请求地址
4.  
   endpoint: oss-cn-beijing.aliyuncs.com

   secretKey: XXXXXXFBaNzv85rqiks804mGXXXXXX
9.  
   #阿里云存储空间名
10.  
    bucketname: home
11.  
    #阿里服务器的域名
12.  
    fileHost: http://home.oss-cn-beijing.aliyuncs.com/
13.  
    #上传文件路径
14.  
    filePath: upload
