Spring MVC 5 file upload example

In the previous article, We have discussed the basic of Spring MVC with hello world example. In this article, We are going to discuss Spring MVC 5 file upload example

Tools used:

  1. JDK 1.8
  2. Spring 5
  3. Maven
  4. Tomcat 8
  5. Favorite IDE

Spring allows us to enable this multipart support with pluggable MultipartResolver objects. The framework provides one MultipartResolver implementation for use with Commons FileUpload and another for use with Servlet 3.0 multipart request parsing.

  •  Commons FileUpload

Spring uses a MultipartResolver interface to upload the file in a web application, two of the implementation :

  • StandardServletMultipartResolver – Servlet 3.0 multipart request parsing.
  • CommonsMultipartResolver – Classic commons-fileupload.jar

The Commons FileUpload package makes it easy to add robust, high-performance, file upload capability to your servlets and web applications.

FileUpload parses HTTP requests which conform to RFC 1867, “Form-based File Upload in HTML”. If an HTTP request is submitted using the POST method, and with a content type of “multipart/form-data”, then FileUpload can parse that request, and make the results available in a manner easily used by the caller.

Below is maven dependency of Commons FileUpload jar.

Spring MVC 5 file upload example:

Step 2: Pom.xml

Here is our pom.xml with spring MVC maven dependency and other required dependencies.

Step 4: Configuration file

As we explained in the last article, here we also new two configuration file such as web.xml and dispatcher-servlet.xml. 

We need to configure the multipartResolver bean to handle the multipart file upload request. This bean configuration is done in the dispatcher-servlet.xml file.

File: web.xml

File: dispatcher-servlet.xml


Step 5: Spring MVC Controller class

Let us create Controller class to handle the file upload request.


Step 6: Spring File Upload Form Views

We will create JSP pages to allow single file uploads in spring web application.


That’s it, We have created Spring MVC 5 file upload example. Run this application in tomcat server and below is the output of the application.
