Configure the resource folder in the Spring-Boot project

---

Preface

Under what circumstances need to configure resource folders?
When the project needs to read files other than the static folder, it needs to be configured as a resource folder so that it can be accessed by users.
Application scenario: background management upload resources, when the foreground needs to view, for example: upload a video in the background, the user in the foreground needs to watch the video. Two projects need to be on the same server. At this time, the video file can be placed anywhere on the server in the background, and the front desk configures this location as a resource folder for users to access, then the user can read the video.
