How to display uploaded image in Spring MVC web application?

File: gfg-servlet.xml – This is the gfg-servlet.xml file located in ” /src/main/webapp/WEB-INF/gfg.servlet.xml “. This file handles all HTTP requests for web applications. The annotation-driven enable the spring @Controller function, resource-mapping helps in handling HTTP requests for all resources.

The bean configuration helps in identifying and scanning the jsp located in the views folder. The component-scan locates and allocated beans according to the mentioned annotation. Also added a resource mapping to map all the resources to the view a page. Step 4: A bean with id as multipartResolver will help in instantiating the CommonsMultipartResolver,

Step 7: The UploadFileController class in the com.gfg.controller has was methods for two requests to be mapped. The upload method is a get mapping and simple redirects to the fileform.jsp view page. The fileUpload method sends a Post request and redirects the showupload page.

package com.gfg.controller; import java.io.File; import java.io.FileOutputStream; import javax.servlet.http.HttpSession; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.multipart.commons.CommonsMultipartFile; @Controller public class UploadFileController @RequestMapping (value = “/uploadfile”, method = RequestMethod.POST) public String fileUpload( @RequestParam ( “thisfile” ) CommonsMultipartFile file, HttpSession s, Model mod) catch (Exception e) return “showupload” ; } }

Step 8: The fileform.jsp in the views folder defines the upload form with enctype as multipart/form-data. We’ve used bootstrap for the proper styling of the page. Example

< html lang = "en" > < head > < meta charset = "utf-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1, shrink-to-fit=no" > < link rel = "stylesheet" href = "" integrity = "sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin = "anonymous" > < title >File uploader < body > < h1 >Upload File < form action = "uploadfile" method = "post" enctype = "multipart/form-data" > < div class = "form-group" > < label for = "formFile" class = "form-label" >Upload Your file < input name = "thisfile" class = "form-control" type = "file" id = "formFile" > < button class = "btn btn-secondary" >Upload < script src = "" integrity = "sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin = "anonymous" > < script src = "" integrity = "sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin = "anonymous" > < script src = "" integrity = "sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin = "anonymous" >

The showupload.jsp page displays the uploaded image using jsp to map the image url.

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding=”UTF-8″%> < html > < head > < meta charset = "UTF-8" > < title >Insert title here < body > < h1 >File Uploaded < img src = "“/>

After adding all the classes and configuration file, the project structure should look something like this: Step 9: Now it’s time to run your project, start the Tomcat Server and run your application, now type “http://localhost:8080/SpringMVCFileUpload/upload” in any browser. Output: Upload the image and click on upload this will redirect you to the showupload page and you will see your uploaded image. So we have created a Spring MVC web application with an upload form and displayed the uploaded image on the web. : Spring MVC File Upload – GeeksforGeeks
