SpringBoot絕對路徑說明-有解無憂

我是 SpringBoot Web 開發人員的新手。我需要將影像保存到當前專案中的目錄中。我已將路徑指定為“String uploaddir = "./src/main/imageuploads/" savedadvert.getId();” 但是影像沒有保存到eclipse專案中的“./src/main/imageuploads/”目錄。

@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";
}

這是 ref 的 saveFile 方法。

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);
        }
    
}

我需要把圖片上傳到這個目錄， SpringBoot 絕對路徑說明

當我獲得絕對路徑時，它顯示為“/Users/chathura/eclipse/jee-2021-03/Eclipse.app/Contents/MacOS/./src/main/imageuploads/24/new file.jpg”。無法進入該目錄，但我可以使用終端訪問該目錄。

請告訴我這里的錯誤是什么？

注意：我正在使用 macos

提前致謝

uj5u.com熱心網友回復：

你能試試 'src/main/resources/imagesuploads'（沒有 .）
提醒一下：當您打包應用程式（生產模式）時，此目錄將消失
此目錄應該可以從外部檔案（例如 application.properties）配置

uj5u.com熱心網友回復：

謝謝阿里，您的回復為解決方案提供了線索。因此，我的專案位于 MacOS 磁區上，未經許可我無法寫入檔案。我只是將位置更改為另一個磁區并且它起作用了。

    @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";
}

謝謝
