Struts integrated dropzone.js upload pictures encountered point problems

Q: Cannot get file object and file name in struts background?

Answer: 1. To Dropzone.js search "return xhr.send (formData);"

2. There is a code in front of it:

       for (i = _m = 0, _ref5 = files.length-1; 0 <= _ref5? _m <= _ref5: _m >= _ref5; i = 0 <= _ref5? ++_m:--_ m) {        formdata.append (this. _getparamname (i), files[i], files[i].name);      }

3. Locate the code and change the Formdata.append (...) to the following:

       for (i = _m = 0, _ref5 = files.length-1; 0 <= _ref5? _m <= _ref5: _m >= _ref5; i = 0 <= _ref5? ++_m:--_ m) {          formdata.append ("Files", Files[i], files[i].name);          Formdata.append ("FileNames", Files[i].name);      }

4. Then define the global files,filenames in Java to provide a get, set method to get the file object and name, as follows:

    Privatefile[] files;//uploaded Files    PrivateString[] FileNames;//file name         Publicfile[] GetFiles () {returnfiles; }     Public voidsetfiles (file[] files) { This. Files =files; }     Publicstring[] GetFileNames () {returnFileNames; }     Public voidsetfilenames (string[] fileNames) { This. FileNames =FileNames; }

5. OK, you can test in your method to see if the object has been acquired?

Note: The other configuration information about uploading files is the same as the struts normal upload configuration can be!
