在使用jspSmartUpload.jar上傳圖片時,可以通過以下步驟解決路徑問題:
String rootPath = request.getServletContext().getRealPath("/");
String uploadPath = rootPath + "uploads/"; // 上傳圖片存儲目錄的相對路徑
File uploadDir = new File(uploadPath);
if (!uploadDir.exists()) {
uploadDir.mkdir();
}
SmartUpload smartUpload = new SmartUpload();
smartUpload.initialize(getServletConfig(), request, response);
smartUpload.setUploadPath(uploadPath);
smartUpload.upload();
File smartFile = smartUpload.getFiles().getFile(0); // 獲取上傳文件對象
String fileName = smartFile.getFileName(); // 獲取上傳文件名
String filePath = uploadPath + fileName; // 獲取上傳文件的完整路徑
需要注意的是,在設置上傳路徑時,可以根據實際情況進行適當調整。另外,為了確保上傳圖片的目錄被正確創建,需要在web.xml文件中添加以下內容:
<servlet>
<servlet-name>SmartUpload</servlet-name>
<servlet-class>com.jspsmart.upload.SmartUpload</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>SmartUpload</servlet-name>
<url-pattern>/jspsmartupload/*</url-pattern>
</servlet-mapping>
這樣,就可以使用jspSmartUpload.jar上傳圖片并解決路徑問題了。
