java - 将照片上传到 OpenShift。 Spring MVC

Question

我已在 OpenShift 服务器上部署了 Spring MVC 应用程序的 .war 文件。每个用户都可以在那里更改照片。它在我的本地主机上工作，但我需要在 OpenShift 服务器上上传照片并将每张照片的路径放入数据库。这是我上传文件的方法

@RequestMapping(value = "/user/updateinfo", method = RequestMethod.POST)
public String postAvatar(@RequestParam("file") MultipartFile file, Principal principal) {
    if (file.isEmpty()) {
        return "redirect:/user";
    }

    if (!file.isEmpty()) {
        try {
            String relativeWebPath = "/resources/avatars/";
            String absoluteFilePath = context.getRealPath(relativeWebPath);
            String name = file.getOriginalFilename();
            // String name=file.getOriginalFilename();
            System.out.println(absoluteFilePath);
            String path = absoluteFilePath + "/" + name;
            File convFile = new File(absoluteFilePath + "/" + name);
            this.usersService.addUserAvatar(principal.getName(), "/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/"+name);
            System.out.println(convFile.getAbsolutePath());
            file.transferTo(convFile);
            System.out.println("You have uploaded file");
            return "redirect:/user";
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("Failed to upload");
            return "redirect:/user";
        }
    }
    return " redirect:/user";
}

但是这条路行不通。日志文件向我显示了这个异常

    /var/lib/openshift/56ae274f0c1e664bf3000158/jbossews/null/vr833vqI_wc.jpg
java.io.FileNotFoundException: null/vr833vqI_wc.jpg (No such file or directory)

请帮忙!

解决了这个问题，添加 <Context docBase="/var/lib/openshift/PROJECT_ID/app-root/data" path="/data" />到 .openshift/config/server.xml 到 <HOST>标签。之后我可以通过 https://appname-domain.rhcloud.com/data/photo.jpg 获取我的照片
