• 测试文件

try{
        //判断文件是否存在
        if (file == null){
            throw new RuntimeException("文件不存在");
        }
        //获取文件的完整名称
        String originalFilename = file.getOriginalFilename();
        if (StringUtils.isEmpty(originalFilename)){
            throw new RuntimeException("文件不存在");
        }

        //获取文件的扩展名称  abc.jpg   jpg
        String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);

        //获取文件内容
        byte[] content = file.getBytes();

        //创建文件上传的封装实体类
        FastDFSFile fastDFSFile = new FastDFSFile(originalFilename,content,extName);

        //基于工具类进行文件上传,并接受返回参数  String[]
        String[] uploadResult = FastDFSClient.upload(fastDFSFile);

        //封装返回结果
        String url = FastDFSClient.getTrackerUrl()+uploadResult[0]+"/"+uploadResult[1];
        return new Result(true,StatusCode.OK,"文件上传成功",url);
    }catch (Exception e){
        e.printStackTrace();
    }
    return new Result(false, StatusCode.ERROR,"文件上传失败");
