最近在用spring boot开发项目时，需要上传头像。但是每次在上传成功后，需要显示的时候，img标签链接总是带本地地址localhost，而上传的图片又不在项目目录下，从而导致每次都无法显示。最后通过src访问后台的方式显示头像。

图片上传代码如下：

@RequestMapping("save")public String save(@RequestParam(value = "file") MultipartFile file, userInfo uf, RedirectAttributes attributes, HttpServletRequest request) {    if (uf != null) {        if (!file.isEmpty()) {            String fileName = UUID.randomUUID().toString().replaceAll("-", "") + file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf("."));            String filePath ="/Users/thomas-wu/upload/" + fileName;            System.out.println(filePath);            try {                file.transferTo(new File(filePath));            } catch (IOException e) {                e.printStackTrace();            }            uf.setHead_href("getimgs?address="+filePath);        }    }    String result = userService.saveUser(uf);    JSONObject jb = JSONObject.fromObject(result);    if (jb.getInt("status") == 1 && "信息保存成功".equals(jb.getString("msg"))) {        attributes.addFlashAttribute("error", "信息保存成功");        return "redirect:/user";    }    attributes.addFlashAttribute("error", "信息保存失败");    return "redirect:/edit";}

头像显示代码如下：

@RequestMapping("/getimgs")public void getimg(String address, HttpServletRequest request, HttpServletResponse response) throws IOException{    try {        FileInputStream hFile=new FileInputStream(address);        int i=hFile.available();        byte data[]=new byte[i];        hFile.read(data);        hFile.close();        response.setContentType("image/*");        OutputStream toClient=response.getOutputStream();        toClient.write(data);        toClient.close();    }catch (IOException e){        PrintWriter toClient=response.getWriter();        response.setContentType("text/html;charset=gb2312");        toClient.write("无法打开图片");        toClient.close();    }}
