阿里云对象存储OSS批量上传，单个上传，批量删除，单个删除！

请自行替换秘钥：

#阿里云 OSS src/main/resources/application.properties
#不同的服务器，地址不同
aliyun.oss.file.endpoint=https://oss-cn-hangzhou.aliyuncs.com
aliyun.oss.file.accessKeyId=LTAI5t9wUqCoD42qPGRy8S
aliyun.oss.file.accessKeySecret=WV9W6erbdF2oqH4KIlo5BzNrwaP
#bucket可以在控制台创建，也可以使用java代码创建
aliyun.oss.file.bucketName=zhurenjin-workspace

多个文件批量上传，单个上传，工具类：

public Map<String, Object> Upload(MultipartFile file) throws IOException {
        InputStream inputStream = file.getInputStream();

        // 避免文件覆盖
        String originalFilename = file.getOriginalFilename();
        int iPoint = originalFilename.lastIndexOf(".");
        String fileTypePre = originalFilename.substring(0,iPoint);
        String fileType = originalFilename.substring(iPoint);
        String fileName = UUID.randomUUID().toString()+fileTypePre+fileType;

        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId,accessKeySecret);
        // PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, fileName, inputStream);
        // 创建PutObject请求。
       ossClient.putObject(bucketName,fileName,inputStream);
       // https://zhurenjin-workspace.oss-cn-hangzhou.aliyuncs.com/exampledir/exampleobject.jpg
       String imgUrl = endpoint.split("//")[0] + "//" + bucketName + "." + endpoint.split("//")[1] + "/"+fileName;
       ossClient.shutdown();

        Map<String ,Object> re = new HashMap<String ,Object>();
        Map<String ,Object> imgList = new HashMap<String ,Object>();
        imgList.put("imageUrl",imgUrl);
        re.put("code",200);
        re.put("msg","上传成功");
        re.put("data",imgList);

        return re;

    }

单个文件上传

@PostMapping("uploadAliyunOSSByUtils")
     public AjaxResult uploadAliyunOSSByUtils( @RequestParam("files") MultipartFile img) throws IOException {
        if (!(img.getOriginalFilename().endsWith(".png")) && !(img.getOriginalFilename().endsWith(".jpg")) && !(img.getOriginalFilename().endsWith(".PNG"))) {
            try {
                return AjaxResult.error("文件类型错误，只能为png或者jpg");
            } catch (Exception e) {
                  throw new RuntimeException(e);
            }
        }
        // 调用阿里云工具类进行文件上传
        AliOSSUtils aliOSSUtils = new AliOSSUtils();
        Map<String, Object> upload = aliOSSUtils.Upload(img);
        return AjaxResult.success(upload);
    }

多个文件上传

 // 阿里云存储（多张图片）
    @PostMapping("uploadAliyunOSSByUtilsArrayFils")
    public AjaxResult uploadAliyunOSSByUtilsArrayFils( MultipartFile[] imgList) throws IOException {
        Map<String, Object> objectObjectHashMap = new HashMap<>();
        // List<Object> objectsImages = new ArrayList<>();
        List<Map<String, Object>> objectsImages = new ArrayList<>();
        // 调用阿里云工具类进行文件上传
        for (MultipartFile img : imgList){
            Map<String, Object> uploadImd = aliOSSUtils.Upload(img);
            Map<String, Object> New_ = new HashMap<>();
            New_.put("strImg",uploadImd);
            objectsImages.add(New_);
            // objectsImages.add(uploadImd);
        }
        return AjaxResult.success(objectsImages);
    }

单个删除

 // 阿里云删除单张图片
    @PostMapping("deleteAliyunOSSByUtils")
    public AjaxResult deleteAliyunOSSByUtils(@RequestBody Map<String,String> img) throws IOException {
        // 创建OSSClient实例。

        System.out.println(img);
        boolean b = aliOSSUtils.deleteFile(img);
        return AjaxResult.success(b);
    }

多个删除

 @PostMapping("deleteAliyunOSSByUtilsArrayList")
    public AjaxResult deleteAliyunOSSByUtilsArrayList(@RequestBody List<String> imgList) throws IOException {
        // 创建OSSClient实例。

         boolean b = aliOSSUtils.deleteAllFile(imgList);
        return AjaxResult.success(b);
    }

工具类

 /*删除工具类《单个》*/
    public boolean deleteFile(Map<String,String> fileUrl){
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

        String img = fileUrl.get("img");
        int begin = (endpoint.split("//")[0] + "//" + bucketName + "." + endpoint.split("//")[1] + "/").length(); //找到文件路径的开始下标
        String deleteUrl = img.substring(begin);
        try {
            // 删除文件请求
            VoidResult voidResult = ossClient.deleteObject(bucketName, deleteUrl);
            System.out.println(voidResult+"删除chengg11111??222");
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
    /*删除工具类《多个》,主要就是要获取到相应的文件后缀，String deleteUrl = objImg.substring(begin);*/
    public boolean deleteAllFile(List<String> keys){
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
        List<String> keysBox= new ArrayList<>();
        int begin = (endpoint.split("//")[0] + "//" + bucketName + "." + endpoint.split("//")[1] + "/").length(); //找到文件路径的开始下标
        for(String objImg : keys) {
            String deleteUrl = objImg.substring(begin);
            keysBox.add(deleteUrl);
        }
        try {
            DeleteObjectsResult deleteObjectsResult = ossClient.deleteObjects(new DeleteObjectsRequest(bucketName).withKeys(keysBox).withEncodingType("url"));
            List<String> deletedObjects = deleteObjectsResult.getDeletedObjects();
            try {
                for(String obj : deletedObjects) {
                    String deleteObj =  URLDecoder.decode(obj, "UTF-8");
                    System.out.println(deleteObj);
                }
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
