注册用户时，数据库将存储图像的url。

@RequestMapping("/addMembers")
    public String addMembers(@ModelAttribute(value = "member") Members member, @RequestParam("file") MultipartFile file, HttpServletRequest request,HttpSession session) {
        Integer flag = 0 ;
        try {
            if (!file.isEmpty()) {
                String fileName = file.getOriginalFilename();
                member.setMprofile("/upload/member/" + member.getMemacc() + "/" + fileName);
                String filePath = "C:/Users/jpg74/IdeaProjects/jason/src/main/resources/static/upload/member/"+member.getMemacc() + "/";
                File destination = new File(filePath + fileName);
                if(!destination.exists()){
                    destination.mkdirs();
                }
                try {
                    file.transferTo(destination);
                    logger.info("" +
                            "Upload Success!!!");
                } catch (IOException e) {
                    logger.error(e.toString(), e);
                }
            }
            flag = memberMapper.addMember(member);
        } catch (Exception e) {
            logger.error(e.toString(), e);
        }
        if(flag > 0)
            return "front-end/login/login";
        else
            return "404";
    }

然后用户希望在其个人资料中显示信息。但是即使图像的url是正确的，图像也不能正确读取。

<figure id='a_mprofile'>
       <img id='mprofile' class="pimg" th:src="${ member.getMprofile()}">
</figure>

我寻找解决方案，比如从https://dev.to/suin/spring-boot-developer-tools-how-to-enable-automatic-restart-in-intellij-idea-1c6i.
现在我必须按ctrl+f9刷新tomcat。我怎样才能解决这个问题。谢谢您！！！
