Struts文件上传
    
    
1.       页面配置：
<form action="upload.do" method="post" enctype="multipart/form-data">
   
       标题：<input type="text" name="title"><br>
   
       文件：<input type="file" name="file"><br>
   
       <input type="submit" value="提交">
   
  </form>
   

2.    ActionForm中使用FormFile来接受上传文件，代码如下：
   
    public class UploadForm extends  
   
    private FormFile file;
   
    public FormFile getFile() {
   
       return file;
   
    }
   
    public void setFile(FormFile file) {
   
       this.file = file;
   
    }
   
}
   

3.    在Action中使用FormFile来接收上传文件，代码如下：
   
public ActionForward execute(ActionMapping mapping, ActionForm form,
   
           HttpServletRequest request, HttpServletResponse response) {
   
       ActionForward af = null;
   
       UploadForm uploadForm = (UploadForm) form;// TODO Auto-generated method stub
   
       FormFile myFile = uploadForm.getFile();       
   
       if(myFile!=null){
   
           try {
   
              FileOutputStream fos = new FileOutputStream("c://"+myFile.getFileName());
   
              fos.write(myFile.getFileData());
   
              fos.flush();
   
              fos.close();
   
              af =  mapping.findForward("success");
   
           } catch (Exception e) {
   
              e.printStackTrace();
   
              af =  mapping.findForward("error");
   
           }
   
       }
   
       return af;
   
    }
   
4.       在struts-config.xml中的配置
     
配置form:
<form-bean name="uploadForm" type="com.zsw.struts.form.UploadForm" />
  
配置Action:
  
<action
   
      attribute="uploadForm"
   
      name="uploadForm"
   
      path="/upload"
   
      scope="request"
   
      type="com.zsw.struts.action.UploadAction" >
   
      <forward name="success" path="/upload_success.jsp" />
   
      <forward name="error" path="/upload_error.jsp" />
   
</action>
