SpringBoot absolute path clarification-CodePudding

I'm new to SpringBoot web dev. I need to save an image to a directory in the current project. I have given path as "String uploaddir = "./src/main/imageuploads/" savedadvert.getId();" but the image not save to the "./src/main/imageuploads/" directory in eclipse project.

@RequestMapping(value="/upload", method = RequestMethod.POST)
public String FileUpload(@RequestParam("file1Url") MultipartFile multipartfile, Model model) throws IOException {
    
    model.addAttribute("advertsim",new advertsummary());
    
    advertsummary advert = new advertsummary();
      
    String file1Urlname= StringUtils.cleanPath(multipartfile.getOriginalFilename());
    advert.setFile1Url(file1Urlname);
                                               
    advertsummary savedadvert = AdvertService.addadvert(advert);
    
    String uploaddir = "./src/main/imageuploads/"  savedadvert.getId(); 

    FileUploadUtil.saveFile(multipartfile, file1Urlname, uploaddir);    
    
    return "uploadview";
}

This is the saveFile method for ref.

public static void saveFile(MultipartFile multipartFile, String fileName, String uploadDir) throws IOException {
     Path uploadPath = Paths.get(uploadDir);
     
        if (!Files.exists(uploadPath)) {
            Files.createDirectories(uploadPath);
        }
          
        try (InputStream inputStream = multipartFile.getInputStream()) {
            Path filePath = uploadPath.resolve(fileName);
            System.out.println(filePath.toFile().getAbsolutePath());
            Files.copy(inputStream, filePath, StandardCopyOption.REPLACE_EXISTING);
        } catch (IOException ioe) {       
            throw new IOException("Could not save image file: "   fileName, ioe);
        }
    
}

I need to upload the image to this directory,

when I get the absolute path, it shows like this "/Users/chathura/eclipse/jee-2021-03/Eclipse.app/Contents/MacOS/./src/main/imageuploads/24/new file.jpg". There is no way to go to this directory but I can access that directory using the terminal.

Please tell me what is the mistake here?

Note : I'm using macos

Thanks in advance

CodePudding user response：

Could you try 'src/main/resources/imagesuploads' (without .)
Just a reminder: This directory will disappear when you package your application (production mode)
This directory should be configurable from an external file (application. properties for example)

CodePudding user response：

Thank you Ali, your response gave a lead to the solution. My project sits on MacOS partition therefore, I couldn't write a file without permission. I simply changed the location to another partition and it worked.

    @RequestMapping(value="/upload", method = RequestMethod.POST)
public String FileUpload(@RequestParam("file1Url") MultipartFile multipartfile, Model model) throws IOException {
    
    model.addAttribute("advertsim",new advertsummary());
    
    advertsummary advert = new advertsummary();
      
    String file1Urlname= StringUtils.cleanPath(multipartfile.getOriginalFilename());
    advert.setFile1Url(file1Urlname);
                                               
    advertsummary savedadvert = AdvertService.addadvert(advert);
    
    String uploaddir = "/Volumes/My Data/Fileupload"  savedadvert.getId();  

    FileUploadUtil.saveFile(multipartfile, file1Urlname, uploaddir);    
    
    return "uploadview";
}

Thank you
