从OpenShift服务器获取图像路径. Spring MVC. JSP [英] Get image path from OpenShift server. Spring MVC. JSP

问题描述

从OpenShift服务器获取照片路径时遇到麻烦. 我有一个已经部署在OpenShift服务器上的Spring MVC应用程序. 在那里，每个用户都可以在此处下载个人资料照片.我是这样的.

I have got a trouble while getting photo path from OpenShift server. I have got a Spring MVC app that have deployed at OpenShift server. There, every user could download there profile pics. I do it this way.

@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 = "";
            String absoluteFilePath = "/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/";
            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";
}

我将文件放置在OpenShift服务器上的此路径

I'm putting my files to this path at OpenShift server

/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/

然后，我将需要到达用户页面的该图像的路径放入数据库中

And after that i'm putting to database a path to this image that needed to get at user's page

this.usersService.addUserAvatar(principal.getName(),"/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/"+name);

当我打开用户页面时，它向我显示GET https://appName-domain.rhcloud.com/haine/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/vr833vqI_wc.jpg

When i'm opening user's page it shows me 404 error that GET https://appName-domain.rhcloud.com/haine/var/lib/openshift/56ae274f0c1e664bf3000158/app-root/data/vr833vqI_wc.jpg
