多个文件批量上传,单个上传,工具类:
java
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
java
@PostMapping("uploadAliyunOSSByUtils")
public AjaxResult uploadAliyunOSSByUtils( @RequestParam("files") MultipartFile img) throws IOException {
if (!(img.getOriginalFilename().endsWith(".png")) && !(img.getOriginalFilename().endsWith(".jpg")) && !(img.getOriginalFilename().endsWith(".PNG"))) {

} 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
java
// 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

Map<String, Object> New_ = new HashMap<>();
New_.put("strImg",uploadImd);
objectsImages.add(New_);
// objectsImages.add(uploadImd);
}
return AjaxResult.success(objectsImages);
}
单个删除
java
// 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
java
@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);
}
