Spring Boot文件上传到本地

Controller类对应接口的写法：

    /**
     * 电影图片上传
     */
    @PostMapping("/movieImageUpload")
    public Result<String> movieImageUpload(@RequestParam("file") MultipartFile image) {
        return uploadService.movieImageUpload(image);
    }

实现类的写法：

    @Override
    public Result<String> movieImageUpload(MultipartFile image) {
        try {
            // 获取原始文件名称
            String originalFilename = image.getOriginalFilename();
            // 获取后缀
            String suffix = StrUtil.subAfter(originalFilename, ".", true);
            // 生成新文件名
            String fileName = UUID.randomUUID() + "." + suffix;
            // 保存文件
            image.transferTo(new File(SystemConstants.MOVIE_IMG_DIR, fileName));
            // 返回结果
            log.debug("文件上传成功，{}", fileName);
            return Result.ok(StaticResource.MOVIE_IMAGE_PATH + fileName);
        } catch (IOException e) {
            throw new RuntimeException("文件上传失败", e);
        }
    }
