解决方案
解决方案二：
servlet代码：publicclassUploadServletextendsHttpServlet{privatestaticfinallongserialVersionUID=1L;publicvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{doPost(request,response);}publicvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{request.setCharacterEncoding("gbk");SmartUploadsu=newSmartUpload();StringfileName="";Stringsfilelength="";Stringfiletype="";Stringsuploadtime="";UploadEntityuploadentity=newUploadEntity();try{su.initialize(this.getServletConfig(),request,response);su.upload();Stringtitle=su.getRequest().getParameter("title");Stringremark=su.getRequest().getParameter("remark");su.save("F://upload");Filefile=su.getFiles().getFile(0);fileName=file.getFieldName();intifilelength=file.getSize();sfilelength=Integer.toString(ifilelength);filetype=file.getFileExt();Datedt=newDate();suploadtime=String.valueOf(1900+dt.getYear()+"-"+String.valueOf(1+dt.getMonth())+"-"+String.valueOf(dt.getDate()));uploadentity.setFileName(fileName);uploadentity.setFileLength(sfilelength);uploadentity.setFileType(filetype);uploadentity.setFileUploadTime(suploadtime);uploadentity.setFileTitle(title);uploadentity.setFileDescribe(remark);UploadManageum=newUploadManage();um.upload(uploadentity);request.getRequestDispatcher("/result.jsp").forward(request,response);}catch(Exceptione){e.printStackTrace();}}publicvoidinit(ServletConfigconfig)throwsServletException{}}
解决方案三：
jsp代码：<body><p></p><palign="center">上传信息输入</p><FORMname="myform"METHOD="POST"ACTION="/smartupload/uploadServlet"ENCTYPE="multipart/form-data"><tablewidth="75%"border="1"align="center"><tr><td><divalign="left"><inputtype="FILE"name="FILE1"size="30"></div></td></tr><tr><td><divalign="left"></div></td></tr><tr><td>标题：<inputtype=textname=titlesize=37></td></tr><tr><td>信息描述：<textareaname=remarkcols=50rows=8></textarea></td></tr><tr><tdcolspan="2"><divalign="center"><inputtype="submit"value="提交"></div></td></tr></table></FORM></body>
