简单的struts上传的:
    jsp:
    <body>
      <html:form action="/upload" method="POST" enctype="multipart/form-data">
      <html:file property="theFile"></html:file><br>
      <html:submit>提交</html:submit>
      </html:form>
      </body>
    form:
    import org.apache.struts.action.ActionForm;
    import org.apache.struts.action.ActionMapping;
    import org.apache.struts.upload.FormFile;
    import javax.servlet.http.HttpServletRequest;
    public class UploadForm extends ActionForm{
        private FormFile theFile;
        public void reset(ActionMapping mapping,HttpServletRequest request){
         this.theFile=null;
        }
        public void setTheFile(FormFile theFile){
         this.theFile=theFile;
        }
        public FormFile getTheFile(){
         return this.theFile;
        }
    }
    action:
    import org.apache.struts.action.Action;
    import org.apache.struts.action.ActionForm;
    import org.apache.struts.action.ActionMapping;
    import org.apache.struts.action.ActionForward;
    import org.apache.struts.upload.FormFile;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpSession;
    import com.struts.form.UploadForm;
    import java.io.FileOutputStream;
    import java.io.File;
    /*
     * 测试struts的上传Action
     */
    public class TestUpLoadAction extends Action{
          public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response)throws Exception{
           UploadForm uf=(UploadForm)form;
           FormFile ff=uf.getTheFile();
           HttpSession session=request.getSession();
           String fileName=ff.getFileName();//获取名称
           int size=ff.getFileSize();
           String contentType=ff.getContentType();//获取类型
           byte[] data=ff.getFileData();//获取上传内容
           session.setAttribute("fileName",fileName);
           session.setAttribute("contentType",contentType);
           session.setAttribute("size",size);
           FileOutputStream fo=new FileOutputStream(new File("e:\\"+fileName));//你要保存的地址
           fo.write(data);
           fo.close();
          return mapping.findForward("download");
          }
    }
    
         <form-bean name="uploadform" type="com.struts.form.UploadForm"></form-bean>
    
       <action type="com.struts.action.TestUpLoadAction" path="/upload" name="uploadform">
          <forward name="download" path="/TestStrutsDownload.jsp"></forward>
          </action>
