1.OSS云存储配置

登录阿里云后，找到OSS云存储，地址为：

阿里云登录 - 欢迎登录阿里云，安全稳定的云计算服务平台

 

2.获取accessKeyId和accessKeySecret

3.编写SpringBoot代码

3.1pom.xml文件引入sdk

		<dependency>
			<groupId>com.aliyun.oss</groupId>
			<artifactId>aliyun-sdk-oss</artifactId>
			<version>3.10.2</version>
		</dependency>

完整pom.xml文件如下

</project>

3.2编写代码

package com.iot.util;

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import java.io.*;


public class AliOSSUtil 
    // Endpoint外网访问域名，以上海为例。
   private static String endpoint = "oss-cn-shanghai.aliyuncs.com";
    // accessKeyId 和 accessKeySecret 是先前创建用户生成的
    private static  String accessKeyId = "您的accessKeyId";
    private static String accessKeySecret = "您的accessKeySecret";
    private static String bucketName="您的Bucket 名称";
    public static void uploadFile(String fileName,String saveFileName) throws FileNotFoundException 
        // 创建OSSClient实例。
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
        // 上传文件流。
        InputStream inputStream = new FileInputStream(fileName);
        ossClient.putObject(bucketName, saveFileName, inputStream);
        // 关闭OSSClient。
        ossClient.shutdown();
    
    public static void main(String[] args) throws FileNotFoundException 
        uploadFile("D:\\\\1\\\\Results.csv","app/Results.csv");

4.运行效果

 在云存储中看一下，文件是否上传成功，例如上传成功的文件
