Come on, show! The whole process of SpringBoot OSS integration has not been seen in more detail than this

Preface

Alibaba Cloud Object Storage Service (OSS) is a massive, secure, low-cost, and highly reliable cloud storage service provided by Alibaba Cloud. The data design durability is not less than 99.9999999999% (12 9s), and the service design availability (or business continuity) is not less than 99.995%.

OSS has a platform-independent RESTful API interface. You can store and access any type of data in any application, any time, and any place.

You can use the API, SDK interface, or OSS migration tool provided by Alibaba Cloud to easily move massive amounts of data into or out of Alibaba Cloud OSS. After the data is stored in Alibaba Cloud OSS, you can choose Standard storage as the main storage method for mobile applications, large websites, image sharing, or hot audio and video. You can also choose low-frequency access storage with lower cost and longer storage period ( Infrequent Access) and archive storage (Archive) as storage methods for infrequent access data.

Log in to Alibaba Cloud and enter the console

Click OK and it's built.
