图片上传后端逻辑代码

逻辑：前端上传图片调后端接口，后端上传成功后返回一个路径，再把这个路径放在标签里，最后一起保存入数据库。其中生成的UUID是为了上传照片解决重名的问题


   /**
     * 图片上传
     * @param file
     * @param request
     * @param response
     * @return
     */
    @RequestMapping(value = "/uploadPhoto",method = RequestMethod.POST)
    @ResponseBody
    public Object uploadPhoto(@RequestParam(value = "file",required = false)MultipartFile file, HttpServletRequest request, HttpServletResponse response){
        String prefix="";
        String dateStr="";
        String originalName="";
        //生成UUID
        String uuid=UUID.randomUUID().toString().replace("-","");
        //保存上传
        OutputStream out = null;
        InputStream fileInput=null;
        try{
            if(file!=null){
//                originalName = file.getOriginalFilename();
                originalName = uuid+file.getOriginalFilename();
                String filepath = "E:\\benke\\lx\\travel\\src\\main\\resources\\static\\images\\strategy\\" + originalName;
                //E:\benke\lx\travel\src\main\resources\static\images\hotel\captcha.jpg
                filepath = filepath.replace("\\", "/");
                File files=new File(filepath);
                //打印查看上传路径
                System.out.println(filepath);
                if(!files.getParentFile().exists()){
                    files.getParentFile().mkdirs();
                }
                file.transferTo(files);
            }
        }catch (Exception e){
        }finally{
            try {
                if(out!=null){
                    out.flush();
                    out.close();
                }
                if(fileInput!=null){
                    fileInput.close();
                }
            } catch (IOException e) {
            }
        }
        Map map2=new HashMap<>();
        Map map=new HashMap<>();
        map.put("code",0);
        map.put("msg","");
        map.put("data",map2);
        map2.put("src","/static/images/strategy/"+originalName);
        return map;
