Uploadify is a jquery plugin used to implement file upload functionality.
Generally will buy a HTML5 version of the.
Html
<input id= "custom_file_upload" type= "file" name= "Filedata"/>
Js
The key is to set the path correctly
//Always initiate a request: Http://localhost:8080/jyxt/img/uploadify-cancel.png, do not know where to start?
function Inituploadimge () {$ (' #custom_file_upload1 '). Uploadify ({' swf ': path_t+ ' js/uploadify.swf ',
Spooler url ' uploader ': path_t+ ' manage/fileupload/', ' method ': ' Post ', ' use_query_string ': True, ' Post_params ': {"Hello": encodeURI ("Hello, I Am", "utf-8"), "BaseURL": "User Files/images/linkimages/"}, ' Cancelimage ': path_t+ ' images/cancel.png ', ' buttontext ': ' Browse ', ' buttonimg ': path_t+ ' images/sel.png ', ' Queueid ': ' custom-queue1 ', ' filetypeexts ': ' *.jpg;*.gif;*.png; ', ' filetypedesc ': ' Picture file ', ' removecompleted ': true, ' onSelect Once ': function (event,data) {$ (' #custom-queue1 '). Text (' File crosses! '); }, ' Onuploadsuccess ': function (file, data, response) {$ (' #custom-queue1 '). Text (' upload succeeded '); $ (' #picUrl '). attr ("value", data); } });}
Controller
Stored path settings are more troublesome
//1, Savepath How to set the base path? BaseURL is the path to pass, relative to the webcontent.
//2, when saved, will be saved to Tomcat, should be saved in jyxt ah?
3, Savefile.getabsolute () can get the path of file storage.
4, Request.getservletpath () is the value of uploader
@RequestMapping (value = "/manage/fileupload/", method = requestmethod.post) public void FileUpload (httpservletrequest Request,httpservletresponse response) throws Exception {//set path String baseurl=request.getparameter ("BaseURL"); The path has a problem String Savepath = Request.getsession (). Getservletcontext (). Getrealpath ("") + "/" +BASEURL; Diskfileitemfactory FAC = new Diskfileitemfactory (); Servletfileupload upload = new Servletfileupload (FAC); String filename= ""; File F1 = new file (Savepath); if (!f1.exists ()) {f1.mkdirs (); } list<fileitem> fileList = null; FileList = (list<fileitem>) upload.parserequest (request); Iterator<fileitem> it = Filelist.iterator (); String name = ""; String extname = ""; while (It.hasnext ()) {Fileitem item = It.next (); if (!item.isformfield ()) {name = Item.getname (); if (name = = NULL | | Name.trim (). Equals ("")) {continue; } if (Name.lastindexof (".") >= 0) {extname = name.substring (Name.lastindexof (".")); } object[] test = {"GIF", "png", "JPG", "Doc", "docx", "xls", "xlsx", "ppt", "pptx", "PTF", "rar", "Zip", ""}; if (! Arrayutils.contains (test, extname.tolowercase (). substring (1))) {continue; } file file = null; do {name=dateutil.getnowdatestring (); Filename=savepath + name + extname; File = new file (filename); } while (File.exists ()); File SaveFile = new file (filename); try {item.write (saveFile); } catch (Exception e) {e.printstacktrace (); }}} response.getwriter (). Print (Request.getcontextpath () + "/userfiles/images/linkimages/" +name+extname);
The above code is available. However, because the uploadify version is different, the file path may be problematic. Just take this to record some key issues.
