我想将用户上传的图像放在 WebContent 的“图像”文件夹中。

我试过了 ..

String filePath = request.getContextPath() + "/WebContent/Images/"
                    + userForm.getUploadedFile().getFileName();

但它给出了一个 FileNotFound 异常......

java.io.FileNotFoundException: \NewStrutsOBL\WebContent\Images\Penguins.jpg (The system cannot find the path specified)

WebContent 未部署在服务器上，因为它仅用于 Eclipse。所以从路径中删除 Webcontent 并尝试一下。

filePath 包含一个相对文件，您尝试使用需要绝对文件的方法加载 filePath。

尝试

filePath = servlet.getRealPath("Images/"
                + userForm.getUploadedFile().getFileName());
