java代码上传本地图片返回地址

有时候我也很迷这个到底是怎么上传的，写这篇为了给自己看的，大家可参照

 @Value("${constantvalue.uploadPath}")
    private String uploadPath;
    @Value("${constantvalue.hostname}")
    private String hostname;
    /**
     * 上传图片
     */
    @PostMapping( "/uploadKD/地址")
    public Map<String, Object>  uploadKD(MultipartFile[] imgFile) throws Exception {
        Map<String,Object> map=new HashMap<>();
        //上传文件
        for (int i = 0; i < imgFile.length; i++) {

        String filename = imgFile[i].getOriginalFilename();
        String suffix = filename.substring(filename.lastIndexOf(".") + 1);
        filename= UUIDUtils.getOrderId()+"."+suffix;
            String imgURL="/upload/地址/"+filename;
            File dest=new File(uploadPath+imgURL);
            if(!dest.getParentFile().exists()){
                dest.getParentFile().mkdirs();
            }
            imgFile[i].transferTo(dest);
            map.put("error", 0);
            map.put("url", hostname+imgURL);

        }
        return map;
    }
