spring:
    resources:
      static-locations: classpath:static/**spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,file:${filePath}

upload.java

    @PostMapping("/uploadImgToLocal")
    public String uploadImg(MultipartFile uploadFile, HttpServletRequest req){
        //获取文件名
        String fileName = uploadFile.getOriginalFilename();
        //获取文件后缀名
        String suffixName = fileName.substring(fileName.lastIndexOf("."));
        //重新生成文件名
        fileName = UUID.randomUUID()+suffixName;
        //添加日期目录
        String format = sd.format(new Date());
        //指定本地文件夹存储图片
        String filePath = "D:/Desktop/mow/upload/"+format+"/";
        File file = new File(filePath,fileName);
        if (!file.getParentFile().exists()){
            file.getParentFile().mkdirs();
        }
        try {
            //将图片保存到static文件夹里
            file.createNewFile();
            uploadFile.transferTo(new File(filePath+fileName));
            return  "http://"+req.getRemoteHost()+":"+req.getServerPort()+"/"+format+"/"+fileName;
        } catch (Exception e) {
            e.printStackTrace();
            return "false";
        }
    }
