各位大侠，大家下午好。
最近在忙文件上传的东西，在网上找了几个案例，终于被我找到一个可以成功上传的例子。
这个例子能够将文件上传上去，但tomcat后台说文件拒绝访问，还有一大堆的exception......可文件确真的是传上去了......
贴上servlet处理代码：
- Java code
package com.test.servlet;import java.io.File;import java.io.IOException;import java.util.List;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.fileupload.FileItem;import org.apache.commons.fileupload.disk.DiskFileItemFactory;import org.apache.commons.fileupload.servlet.ServletFileUpload;public class UploadServlet extends HttpServlet { @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub // super.doPost(arg0, arg1); request.setCharacterEncoding("UTF-8"); DiskFileItemFactory factory = new DiskFileItemFactory(); String path = request.getSession().getServletContext().getRealPath( "/upload"); factory.setRepository(new File(path)); factory.setSizeThreshold(1024 * 1024); ServletFileUpload upload = new ServletFileUpload(factory); try { List<FileItem> list = upload.parseRequest(request); for (FileItem item : list) { if (item.isFormField()) { String name = item.getFieldName(); String value = item.getString("UTF-8"); request.setAttribute(name, value); } else { String name = item.getFieldName(); String value = item.getName(); int start = value.lastIndexOf("\\"); String fileName = value.substring(start + 1); request.setAttribute(name, fileName); item.write(new File(path, fileName)); } } } catch (Exception e) { e.printStackTrace(); } request.getRequestDispatcher("/result.jsp").forward(request, response); }}
