With this configuration, any request with enctype as multipart/form-data will be handled by multipartResolver before passing on to the Controller class. ("Unable to locate MultipartResolver with name 'multipartResolver': no multipart request handling provided") This.multipartResolver = ((MultipartResolver)context.getBean("multipartResolver", MultipartResolver.class)) private void initMultipartResolver(ApplicationContext context) If you will look into the source code of DispatcherServlet class, you will see that a MultipartResolver variable with name multipartResolver is defined and initialized in below method. Notice that I am setting maximum upload size limit by providing the maxUploadSize property value for multipartResolver bean. Our final Spring configuration file looks like below. To utilize Apache Commons FileUpload for handling multipart requests, all we need to do is configure multipartResolver bean with class as .commons.CommonsMultipartResolver. We will take the input array and parse the file data and store it in the given file name. ![]() Also note that for multiple files, the form field “file” and “name” are the same in the input fields, so that the data will be sent in the form of an array. The important point to note is that form enctype should be multipart/form-data, so that Spring web application knows that the request contains file data that needs to be processed. Notice that these files are simple HTML files, I am not using any JSP or Spring tags to avoid complexity. We will create two JSP pages to allow single and multiple file uploads in spring web application. Below is the dependency snippet from my pom.xml file. Maven Dependencies for Apache Commons FileUploadįirst of all, we need to add Apache Commons FileUpload dependencies in our pom.xml file, so that required jar files are part of the web application. Most of the part is the boiler-plate code generated by STS tool, we will focus on the changes that are required to utilize Spring file upload integration. We will create a simple Spring MVC project in STS that will look like below image. The process to upload files is very easy and requires simple configurations. Spring MVC framework provides support for uploading files by integrating Apache Commons FileUpload API. Today we will learn about Spring File upload, specifically Spring MVC File Upload for single and multiple files. We have earlier seen how to upload files in Servlet and Struts2 File Uploading. File Uploading is a very common task in any web application.
