java - spring中如何获取项目目录的路径？

Question

我正在尝试使用我的 jsp 表单上传图像文件。我能够成功上传它，但不在我想要的目录中。

@Controller
public class ProductController {
  private Path path;
  
  @Autowired
  private ProductService productService;
  
  @RequestMapping(value="/admin/addProduct")
  public String addProduct() {
    return "addProduct";
  }
  
  @RequestMapping(value="/admin/addProduct", method= RequestMethod.POST)
  public String addNewProduct(@ModelAttribute("product") Product products,
  BindingResult result,HttpServletRequest request,@RequestParam("prodImage") 
  MultipartFile file) {
    System.out.println("adding product");
        System.out.println(path);
        if(result.hasErrors()) {
      return "addProduct";
    }
    productService.saveProduct(products);
    
    MultipartFile productImage = file;
    String rootDir = request.getSession().getServletContext().getRealPath("/");
    System.out.println(rootDir);
    path = Paths.get(rootDir+"//WEB-INF//resources//images//"+products.getId()+
    ".jpg");
    System.out.println("path :"+path);
    if(productImage != null && !productImage.isEmpty()) {
      System.out.println("inside not null product image");
      try {
        productImage.transferTo(new File(path.toString()));
                System.out.println("after saving image");

      }catch (Exception ex) {
        ex.printStackTrace();
        throw new RuntimeException("product image saving failed",ex);
      }
    }
        
    return "redirect:/admin/productInventory";
  }
  
  @RequestMapping("/admin/productInventory")
  public String productInventory() {
    return "productInventory";
    
  }

}

这是正在打印的当前目录位置:-

/mnt/7A46BE1454633621/eclipseworkspace/ecommerce/target/ecommerce/

  path :/mnt/7A46BE1454633621/eclipseworkspace/ecommerce/target/ecommerce/ 
WEB-INF/resources/images/5.jpg

我想将我的图像上传到 WEB-INF/resources/images 中。我该怎么做？

您需要检查类路径是否设置，然后您可以使用classpath:/WEB-INF/resources/images/路径来上传和下载图像。
