Question

ajax上传文件提交时，enctype=multipart/form-data怎么带过去？

Answer 1

form中的字段，加上get set方法        

private FormFile file;

private String filename;

private String filesize;

action 部分:

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

String dir="D:/";

UpFileForm uff=(UpFileForm)form;

FormFile file=uff.getFile();

if(file.getFileSize()==0){

return mapping.findForward("success");

}

String fname=file.getFileName();

String size=Integer.toString(file.getFileSize())+"bytes";

InputStream streamIn=file.getInputStream();

OutputStream streamOut=new FileOutputStream(dir+"/"+fname);

int bytesRead=0;

byte[] buffer=new byte[8192];

while((bytesRead=streamIn.read(buffer,0,8192))!=-1){

streamOut.write(buffer,0,bytesRead);

}

streamOut.close();

streamIn.close();

uff.setFilename(fname);

uff.setFilesize(size);

file.destroy();

return mapping.findForward("success");

}

这样将上传的文件存在d盘。
