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();
    }


}
