Spring 3 File Upload Example. I had the opportunity to figure out how to do file uploads using Spring 3 the other day and I couldnt find anything that pulled it all together. What follows is a complete example of how to do MVC based file uploads with Spring 3. Im going to assume you know something about Spring and their MVC configuration in general. If you want a simple MVC example to start with check out their SVN MVC Basic sample. There is a decent amount of boiler plate work so Ive created a project zip file with all the code, a build file and configuration in it you just need to add the libraries. This article demonstrates file uploads using Web API 2. The examples use the MultipartFormDataStreamProvider class. The controller implementation saves the files in. Can I use the following jQuery code to perform file upload using post method of an Ajax request. POST, timeout 50000, url url, data. First lets start by gathering up all the libraries we are going to need see the end of the post for the directory layout I used or just unzip the project. Grab a copy of the Spring 3 libraries, at this time the latest version is spring framework 3. RELEASE A. zip and that is what I used for the following example. For the file upload part there are two non Spring dependencies as well Apache Commons File. Upload and Apache Commons IO. If you want to use the example project from the zip just copy all the jar files to the lib directory. Next it is worth a quick look at the information provided in the Spring documentation about MVC multipart. It touches on what needs to be done but leaves out a full example. In documentation you will see that they talk about using a multipart resolver and that can be found at the end of webWEB INFspringapp config.

Multiple file upload forms are sometimes essential for your web application but managing upload from multiple file input boxes becomes a bit tedious and lengthy. But thanks to j. Query using which we can make this task easier too. Today Im going to create an AJAXified multiple file upload form that uses a lot lesser server side code and also provides a very nice user interface. For this tutorial, ill be using latest version of j. Query and Ajax upload library by Andrew Valums. Grab both libraries and add them to your page header. The HTML Structure. As i said, the upload form will be intuitive, we wont be using the classic File input box. So, First of all create the upload button on which user will click to open the File Selection dialog. Upload Filelt div. You can use any element you want for the button. I just applied some basic style to this div, you can apply any style you wish to make it look more attractive. Arial, Helvetica, sans serif. I also added a span element next to upload button to show various messages during processing. And to show the uploaded files to the user, i added an unordered list next to the button. Heres the complete html code. Upload Button. Upload Filelt div lt span idstatus lt span. List Files. The PHP Code. To upload the files to server, heres a basic file uploading script in PHP that displays success if file uploaded successfully otherwise displays error. FILESuploadfilename. FILESuploadfiletmpname, file. The Java. Script Code. And lastly the javascript part. The AJAX Upload library you included earlier will do all the heavy lifting for you. Heres the Java. Script Code youll need. Utility Programs Wiki'>Utility Programs Wiki. Uploadupload. Ajax. Uploadbtn. Upload,. Name of the file input box. Submit functionfile, ext. Only JPG, PNG or GIF files are allowed. Uploading on. Complete functionfile, response. On completion clear the status. Add uploaded file to list. Tofiles. htmllt img src. Classsuccess. Tofiles. Classerror. Code explanation to use the AJAX Upload library we need to initialize the Ajax. Upload object and provide it with parameters. The first parameter is the id of the button element on which the user will click and second is the server side script thatll handle file upload. The second parameter can accept an array of various options to give you more control over the process. And thats exactly what ive done. The action field is the path to server side script,name is the name of file input boxhidden which will be used for upload. If you change this value, make sure to change the server side script corresspondinly. Submit lets you perform some function before the file is uploaded e. Complete lets you perform some action after the upload is complete e. Ive shown the uploaded image to the user. And if you want to limit the number of files that a user can upload at a time, simply use this. Submit or on. Complete to disable the upload button after checking for some condition. Note The file upload using AJAX is not true ajax as it uses hidden iframe to upload the form data but his whole process is transparent by using the AJAX Upload library and gives a feel of AJAXified file upload.
