In my Spring MVC project I am trying to upload a file via a simple form.

HTML Form:

Answer 1

The fast solution for me was the following

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>





    
        File to upload: 
 
        Name: 
 
 
         Press here to upload the file!
     

The controller code is the following:

package com.student.controller;

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.security.Principal;
import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
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.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

@Controller
@RequestMapping("/file")
public class FileUploadController {

    @RequestMapping(value = "", method = RequestMethod.GET)
    public String index(ModelMap modelMap,Principal principal,HttpServletRequest request) {
        return "uploadfile";
    }

    @RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
    public @ResponseBody String uploadFileHandler(@RequestParam("name") String name, @RequestParam("file") MultipartFile file) {

        if (!file.isEmpty()) {
            try {
                byte[] bytes = file.getBytes();

                // Creating the directory to store file
                String rootPath = System.getProperty("catalina.home");
                File dir = new File(rootPath + File.separator + "tmpFiles");
                if (!dir.exists())
                    dir.mkdirs();

                // Create the file on server
                File serverFile = new File(dir.getAbsolutePath()
                        + File.separator + name);
                BufferedOutputStream stream = new BufferedOutputStream(
                        new FileOutputStream(serverFile));
                stream.write(bytes);
                stream.close();



                return "You successfully uploaded file=" + rootPath+name;
            } catch (Exception e) {
                return "You failed to upload " + name + " => " + e.getMessage();
            }
        } else {
            return "You failed to upload " + name
                    + " because the file was empty.";
        }
    }

}

I added the following code in spring dispatcher file
