java 阿里云上传文件到OSS，并返回文件路径

pom.xml依赖：

        
            com.aliyun.oss
            aliyun-sdk-oss
            3.12.0
        

        
        
            com.aliyun
            oss-client
            3.0.2
        

上代码：

/**
     * 图片上传
     */
    @PostMapping("/imageUpload")
    @ApiOperation(value = "图片上传")
    @ApiImplicitParams({
        @ApiImplicitParam(name = "imageFile", value = "图片", required = true),
        @ApiImplicitParam(name = "directory", value = "根目录：业务文件夹", required = true),
        @ApiImplicitParam(name = "fileName", value = "文件名字：业务文件夹", required = true),
    })
    public AjaxResult driverPhoto(@RequestParam("imageFile") MultipartFile file, @RequestParam("directory") String directory
        , @RequestParam("fileName") String fileName) throws IOException {
        if (!file.isEmpty()) {
            OSSClientUtil ossClientUtil=new OSSClientUtil();
            String busDirectory=directory +"/"+new SimpleDateFormat("yyyy-MM-dd").format(DateUtils.getNowDate());
            String filename = fileName+System.currentTimeMillis()+ UUID.randomUUID().toString().replaceAll("-", "") + file.getOriginalFilename().substring(file.getOriginalFilename().toString().lastIndexOf((".")));
            String imgFilePath = ossClientUtil.uploadFile(filename, busDirectory,new ByteArrayInputStream(file.getBytes()) );
            return AjaxResult.success(imgFilePath);
        }
        return AjaxResult.error("上传图片异常");
    }
