webwork下uplodify的使用步骤：
1.修改web.xml文件中的拦截器配置，如下：

 

webwork
com.opensymphony.webwork.dispatcher.FilterDispatcher

webwork
*.action

 

2.在类路径下的webwork.properties中修改有关上传功能的配置，如下：

 

### multipart setting
webwork.tag.altSyntax = true
webwork.multipart.saveDir=javax.servlet.context.tempdir
webwork.multipart.maxSize=2097152
webwork.multipart.parser=jakarta

 

3.新建以xwork_upload.xml配置文件，文件内容如下：

 

 
  
   
    10000000
   
   
    
    
   
  
  
  
  doImageUpload">
   
   
   
    
 

 

4.将刚刚新建的xwork_upload.xml配置文件引入到xwork.xml配置文件中

 

 

5.根据配置文件新建net.survey.admin.UploadAction，内容如下：

 

public class UploadAction extends ActionSupport implements ServletRequestAware, ServletResponseAware{
    private HttpServletRequest request;
    private HttpServletResponse response;
 
    private File images;    //和在JS中指定的fileObjName的值相同
    private String imagesFileName;    //[fileName]FileName    获得上传文件的名称
    private String imagesContentType;//[fileName]ContentType  获得上传文件的类型
 
 public String doImageUpload() throws Exception {
  upload("img", imagesFileName, images);
  return null;
 }
 
 public void upload(String dir, String name, File file) throws Exception{
  request.setCharacterEncoding("utf-8");
  response.setContentType("text/html; charset=utf-8");
  String savePath = new String(request.getServletContext().getRealPath("/") + "\\upload\\" + dir);
  if(!new File(savePath).exists())new File(savePath).mkdirs();
  String file_name = new SimpleDateFormat("yyyy-MM-dd HH.mm.ss").format(new Date()) + "_" + new String(name.getBytes("gbk"), "UTF-8"); // 唯一且不重复的文件名
  //文件名形如：ID.文件后缀
  FileOutputStream fos = new FileOutputStream(savePath + "\\" + file_name);
  FileInputStream fis = new FileInputStream(file);
  Streams.copy(fis, fos, true);
  /*byte[] buffer = new byte[1024];
  int len = 0;
  while ((len = fis.read(buffer)) > 0) {
   fos.write(buffer, 0, len);
  }
  fos.close();
  fis.close();*/
  PrintWriter out = response.getWriter();
  //这个地方不能少，否则前台得不到上传的结果
  out.write("1");
  out.close();
 }
 
 @Override
 public void setServletResponse(HttpServletResponse response) {
  this.response = response;
 }

 @Override
 public void setServletRequest(HttpServletRequest request) {
  this.request = request;
 }

 public File getImages() {
  return images;
 }

 public void setImages(File images) {
  this.images = images;
 }

 public String getImagesFileName() {
  return imagesFileName;
 }

 public void setImagesFileName(String imagesFileName) {
  this.imagesFileName = imagesFileName;
 }

 public String getImagesContentType() {
  return imagesContentType;
 }

 public void setImagesContentType(String imagesContentType) {
  this.imagesContentType = imagesContentType;
 }
}

 

6.建立jsp页面，内容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<% 
 String path = request.getContextPath(); 
 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%>
