方式一

public String addAli(MultipartFile file){
        String endpoint = "oss-xxxxxxxxxxxxcs.com";

        String accessKeySecret = "L9bxxxxxxxxxxxxxxxxxLnq";

        String uploadUrl = null;
        try {
            // 创建OSSClient实例
            OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
            InputStream inputStream = file.getInputStream();
            String filename = file.getOriginalFilename();
            // 在文件名称中添加随机的唯一的值，防止名称一样时文件的覆盖
            String uuid = UUID.randomUUID().toString().replaceAll("-","");
            // 文件类型
            String fileType = filename.substring(filename.lastIndexOf("."));
            filename = uuid + fileType;

            // 把文件安装日期进行分类，会自动创建文件夹
            String datePath = new DateTime().toString("yyyy/MM/dd");
            filename = datePath + "/" + filename;

            ossClient.putObject(backetName, filename, inputStream);

            // 关闭OSSClient
            ossClient.shutdown();

            // 上传文件之后的路径，自己拼接
            uploadUrl = "https://"+backetName+"."+endpoint+"/"+filename;

        } catch (IOException e) {
            e.printStackTrace();

            OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
            ossClient.putObject(bucketName, objectName, inputStream);

            // 设置URL过期时间为6小时
            Date expiration = new Date(System.currentTimeMillis() + 3600 * 1000 * 6);
            // 生成以GET方法访问的签名URL，可以直接通过浏览器访问相关内容
            URL url = ossClient.generatePresignedUrl(bucketName, objectName, expiration);
            // 关闭OSSClient。
            ossClient.shutdown();
            uploadUrl = url.toString();
            System.out.println(uploadUrl);
        } catch (IOException e) {

        }
        return AjaxResult.success(uploadUrl);
