如下图所示

@ApiOperation("文件上传")
    @PostMapping("/upload")
    public RespBean upload(@RequestPart MultipartFile multipartFile) throws IOException {
        
        String hostname = "域名"; // 域名
        String accessKey = "AccessID"; // 秘钥ID
        String secretKey = "AccessSecretKey"; // 秘钥值
        String bucketName = "桶名称"; // 桶名称
        String objectKey = "upload/"+multipartFile.getOriginalFilename(); // 设置指定路径
        // multipartFile.getOriginalFilename() 文件名
        // 创建 AmazonS3Client
        ClientConfiguration opts = new ClientConfiguration();
        opts.setSignerOverride("S3SignerType"); //单次上传
        AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
        AmazonS3Client client = new AmazonS3Client(credentials, opts);
        client.setEndpoint(hostname);
        // 上传文件（Object）
        byte[] content = multipartFile.getBytes();
        // 解决文件文件只能下载不能查看问题
        // ObjectMetadata objectMetadata = new ObjectMetadata();
      //objectMetadata.setContentType(getcontentType(multipartFile.getOriginalFilename().substring(multipartFile.getOriginalFilename().lastIndexOf("."))));
        // objectMetadata 设置为空默认为每次打开都会下载文件
        System.out.println(objectMetadata.getContentType());
        client.putObject(bucketName, objectKey,
                new ByteArrayInputStream(content), objectMetadata);
        client.setObjectAcl(bucketName,objectKey, CannedAccessControlList.PublicRead);
        // 关闭 client
        client.shutdown();
        // 访问路径 https://桶.域名/相对路径
        return RespBean.success("成功",client.getResourceUrl(bucketName,objectKey));
    }

// 预览图片格式设置（解决图片上传之后访问只能下载不能预览问题）
        public static String getcontentType(String FilenameExtension) {
        
            if (FilenameExtension.equalsIgnoreCase(".bmp")) {
        
                return "image/bmp";
            }
            if (FilenameExtension.equalsIgnoreCase(".gif")) {
        
                return "image/gif";
            }
            if (FilenameExtension.equalsIgnoreCase(".jpeg") ||
                    FilenameExtension.equalsIgnoreCase(".jpg") ||
                    FilenameExtension.equalsIgnoreCase(".png")) {
        
                return "image/jpg";
            }
            if (FilenameExtension.equalsIgnoreCase(".html")) {
        
                return "text/html";
            }
            if (FilenameExtension.equalsIgnoreCase(".txt")) {
        
                return "text/plain";
            }
            if (FilenameExtension.equalsIgnoreCase(".vsd")) {
        
                return "application/vnd.visio";
            }
            if (FilenameExtension.equalsIgnoreCase(".pptx") ||
                    FilenameExtension.equalsIgnoreCase(".ppt")) {
        
                return "application/vnd.ms-powerpoint";
            }
            if (FilenameExtension.equalsIgnoreCase(".docx") ||
                    FilenameExtension.equalsIgnoreCase(".doc")) {
        
                return "application/msword";
            }
            if (FilenameExtension.equalsIgnoreCase(".xml")) {
        
                return "text/xml";
            }
            return "image/jpg";
        }
