１.在完好的struts2中再倒入如下两个包 commons-fileupload-1.2.1.jar commons-io-1.4.jar

２.Action类

package com.sterning; import java.io.File;

import javax.servlet.ServletContext;

import org.apache.commons.io.FileUtils;

import org.apache.struts2.util.ServletContextAware; import com.opensymphony.xwork2.ActionSupport;

public class StrutsFileUpload extends ActionSupport implements ServletContextAware {

private File upload;// 实际上传文件

private String uploadContentType; // 文件的内容类型 private String uploadFileName; // 上传文件名 private String fileCaption;// 上传文件时的备注 private ServletContext context;

public String execute() throws Exception {

try {

String targetDirectory = context.getRealPath(\"/upload\"); String targetFileName = uploadFileName;

File target = new File(targetDirectory, targetFileName); FileUtils.copyFile(upload, target);

setUploadFileName(target.getPath());//保存文件的存放路径

} catch (Exception e) {

addActionError(e.getMessage()); return INPUT; }

return SUCCESS; }

public String getFileCaption() { return fileCaption; }

public void setFileCaption(String fileCaption) { this.fileCaption = fileCaption; }

public File getUpload() { return upload; }

public void setUpload(File upload) { this.upload = upload; }

public String getUploadContentType() { return uploadContentType; }

public void setUploadContentType(String uploadContentType) { this.uploadContentType = uploadContentType; }

public String getUploadFileName() { return uploadFileName; }

public void setUploadFileName(String uploadFileName) { this.uploadFileName = uploadFileName; }

public void setServletContext(ServletContext context) { this.context = context;

} } ３.页面

上传页面：upload.jsp

<%@ page language=\"java\" contentType=\"text/html; charset=GB2312\"%> <%@ taglib prefix=\"s\" uri=\"/struts-tags\" %>

\" rel=\"stylesheet\" type=\"text/css\" />

文件上传示例

上传成功页面：upload_success.jsp

<%@ page language=\"java\" contentType=\"text/html; charset=GB2312\"%> <%@ taglib prefix=\"s\" uri=\"/struts-tags\"%>

\" rel=\"stylesheet\" type=\"text/css\" />
