第三方服务整合-阿里云OSS上传文件-填坑

發(fā)布時間：2024/9/30 编程问答 23 豆豆

生活随笔收集整理的這篇文章主要介紹了第三方服务整合-阿里云OSS上传文件-填坑小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

如下，引入aliyun-oss失敗：

com.alibaba.cloud:aliyun-oss-spring-boot-starter:unknown

原因:

在2.2.0.RELEASE以后的版本中，OSS依賴被轉(zhuǎn)移到了alibaba/aliyun-spring-boot倉庫中。需引入阿里云服務 Spring Boot Starters 工程的依賴管理。

解決方法

接著再配置文件中添加以下配置，執(zhí)行程序后上傳成功。

spring:application:name: gulimall-third-partycloud:nacos:discovery:server-addr: 127.0.0.1:8848alicloud:access-key: "LTAI4GEBfPJnto1Ut5sWozWa"secret-key: "sJxQJEGBIdwjrbsIz1xdd7MjaAZq6f"oss:endpoint: "oss-cn-beijing.aliyuncs.com"# 本沒有這個屬性, 自己添加bucket: "codingce-product"logging:level:cn.com.codingce: debugserver:port: 30000
