作为 jar 托管时，更新配置文件图像功能不起作用
您好，我是 Springboot 的新手，我正在尝试开发一个应用程序，其功能之一是上传配置文件图像。它在 STS 中工作正常，但是当我将其打包到 jar 中并将其托管在 AWS EC2 环境中时，我在处理该图像时遇到一些错误错误
：
个人资料图片处理程序：
@PostMapping("/process-contact")
public String processContact(@ModelAttribute Contact contact, @RequestParam("profileImage") MultipartFile file,
HttpSession session) {
try {
contact.setUser(user);
user.getContacts().add(contact);
// processing and uploading photo
if (file.isEmpty()) {
System.out.println("File is empty");
contact.setImage("contact.png");
} else {
//Processing Image
InputStream inputStream = file.getInputStream();
Path paths = Paths.get(new ClassPathResource("/static/img").getFile().getPath()+"/" +file.getOriginalFilename());
Files.copy(inputStream, paths, StandardCopyOption.REPLACE_EXISTING);
contact.setImage(file.getOriginalFilename());
}
// Success Message
session.setAttribute("message", new Message("Your contact is added...", "success"));
this.userRepository.save(user);
System.out.println("Successfully Added");
} catch (Exception E) {
E.printStackTrace();
// Failed message
session.setAttribute("message", new Message("Something went wrong "+E.getMessage(), "danger"));
}
return "normal/add_contact_form";
}
它在 IDE 中工作正常后一些研究我发现在 jar 中写入数据的方式是不同的，请帮助我如何也为 jar 实现它。
谢谢

// Failed message
session.setAttribute("message", new Message("Something went wrong "+E.getMessage(), "danger"));
}
