		<version>2.1.4.RELEASE</version>
	</parent>

	<dependencies>

		<!--  Alibaba cloud OSS -->
		<dependency>

New startup class , newly added controller

@Controller
public class OSSController {
    

	@RequestMapping("/getOSSClient")
	public @ResponseBody String getOSSClient() throws FileNotFoundException {
    
		// yourEndpoint Fill in Bucket The region corresponding to Endpoint. East China 1（ Hangzhou ） For example ,Endpoint Fill in for https://oss-cn-hangzhou.aliyuncs.com.
		String endpoint = "endpoint";
		//  Alicloud account AccessKey Have all the API Access rights of , The risk is high . It is highly recommended that you create and use it RAM The user carries out API Visit or daily operations , Please log in RAM Console creation RAM user .
		String accessKeyId = "accessKeyId";
		String accessKeySecret = "accessKeySecret";

		//  establish OSSClient example .
		OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

		//  Fill in the full path of the local file . If no local path is specified , By default, the file stream is uploaded from the local path corresponding to the project to which the sample program belongs .
		InputStream inputStream = new FileInputStream("D:\\VUE\\001.jpg");
		//  Fill in... In turn Bucket name （ for example examplebucket） and Object The full path （ for example exampledir/exampleobject.txt）.Object The full path cannot contain Bucket name .
		ossClient.putObject("Bucket name ", "001.jpg", inputStream);

		//  close OSSClient.
		ossClient.shutdown();
		System.out.println("============================");
		return " Upload successful ";
	}
}

Here we mainly get four parameters ：
1.endpoint
2.accessKeyId（ The application account number has been obtained ）
3.accessKeySecret（ The application account number has been obtained ）
4.Bucket name

endpoint obtain
1）、 Get into OSS home page 、 Click access path , Click Overview

2）、Bucket name
Get into OSS home page , Click on Bucket list

7. Start project

visit ：http://localhost:8080/getOSSClient
The browser prints and uploads successfully

Enter Alibaba cloud OSS, file management , You can see what I just uploaded 001.jpg The file

Because we don't have read permission , So we can directly access the uploaded files , At this point, we click Details , Copy url You can access the image directly .
