parseRequest(RequestContext)还是parseRequest(HttpServletRequest)

parseRequest(RequestContext)还是parseRequest(HttpServletRequest)?

今天写jsp文件下载时发现

List<FileItem> fileItems = servletFileUpload.parseRequest(request);

报了一个类型不兼容的错，具体提示如下：

The method parseRequest(RequestContext) in the type FileUploadBase is
not applicable for the arguments (HttpServletRequest) 

在网上查过后发现包错了，默认使用的是tomcat的lib文件夹下的类是：

import org.apache.tomcat.util.http.fileupload.FileItem; 
import org.apache.tomcat.util.http.fileupload.FileUploadException; 
import org.apache.tomcat.util.http.fileupload.disk.DiskFileItemFactory; 
import org.apache.tomcat.util.http.fileupload.servlet.ServletFileUpload;
...

而应该要导的是：

import org.apache.commons.fileupload.FileItem; 
import org.apache.commons.fileupload.FileUploadException; 
import org.apache.commons.fileupload.disk.DiskFileItemFactory; 
import org.apache.commons.fileupload.servlet.ServletFileUpload; 
...

commons-fileupload.jar包地址
