本文主要是介绍aliyun图片存储OSS工具类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
pom.xml配置jar包
<!-- oss --><dependency><groupId>com.aliyun.oss</groupId><artifactId>aliyun-sdk-oss</artifactId><version>3.17.4</version></dependency>
yml配置相关key
#oss 配置
oss:#AKaccessKey: accessKey#SKsecretKey: secretKey# 访问域名：以华东1（杭州）为例，Endpoint填写为https://oss-cn-hangzhou.aliyuncs.comendpoint: https://oss-cn-hangzhou.aliyuncs.com# 存储空间：Bucket名称必须全局唯一bucketName: hsope-test#对象objectName: rental/

}
业务使用
存储
上传base64图片，获取到图片地址
OSSUtils.uploadBase64(f.getImage())
显示
根据存储的图片地址，获取到有时效的图片地址，给前端展示
OSSUtils.getUrlByExpiration(f.getImage()))
获取
根据存储的图片地址，获取base64图片
OSSUtils.getImgStr(OSSUtils.getUrlByExpiration(f.getImage()))
完结！
