在使用jspSmartUpload.jar上传图片时,可以通过以下步骤解决路径问题:
String rootPath = request.getServletContext().getRealPath("/");
String uploadPath = rootPath + "uploads/"; // 上传图片存储目录的相对路径
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); // 获取上传文件对象
String fileName = smartFile.getFileName(); // 获取上传文件名
String filePath = uploadPath + fileName; // 获取上传文件的完整路径
需要注意的是,在设置上传路径时,可以根据实际情况进行适当调整。另外,为了确保上传图片的目录被正确创建,需要在web.xml文件中添加以下内容:
<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>
这样,就可以使用jspSmartUpload.jar上传图片并解决路径问题了。
