The version number of the project is in the form of x.x.x, where x is a number, starting from 0, and is not limited to the range 0~9. When the project is in the incubator phase, the first version number is fixed to 0, that is, the version number is 0.x.x.
If your applications are Spring Cloud applications and you need to use Alibaba Cloud's OSS service for file storage (for example, storing commodity image for your e-commerce business), you can use OSS starter. This topic provides an example to illustrate how to use OSS starter to implement object storage for Spring Cloud applications.

Before we start the demo, let's learn how to connect OSS to a Spring Cloud application.
**Note: This section is to show you how to connect to oss. The actual configurations have been completed in the following example, and you only need to specify your accessKeyId, secretAccessKey and region.**
1. Add dependency spring-cloud-starter-alibaba-storage in the pom.xml file in your Spring Cloud project.
