SpringBoot整合TomCat本地图片服务器

 public static final String HEAD_IMG_DIR = "D:/upload/"; // 本地存放图片路径
    //图片上传
    @RequestMapping("/upload")
    @ResponseBody
    public String upload(MultipartFile file) {
        //文件真实上传名字
        String filename = file.getOriginalFilename();
        //文件大小
        Long size = file.getSize();
        String contentType = file.getContentType();
        //文件临时储存到本地
        String folder = HEAD_IMG_DIR;
        //生成保存的文件名字，这个名字要存到数据库中
        String uuid = UUID.randomUUID().toString();
        try {
            file.transferTo(new File(folder +  uuid));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return uuid;  // 返回给前台 uuid   需和信息一起存到数据库
    }
