Code4java: Multiple File Upload Using Spring MVC and Hibernate

Hello Friends,Hope you all are fine,its been very long i posted new post,very hactic schedule,i am going to demonstrate how we can upload file using future provided by Spring 3.0 with hibernate as a backend.

The Code is as given below :

MODEL CLASS

package org.fileupload.model;

import java.util.List;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;

import org.springframework.web.multipart.MultipartFile;

@Entity
@Table(name="trnimage")
public class FileuploadVO {

public int getID() {
return ID;
}

public void setID(int iD) {
ID = iD;
}

public byte[] getData() {
return data;
}

public void setData(byte[] data) {
this.data = data;
}

public String getIMAGE_NAME() {
return IMAGE_NAME;
}

public void setIMAGE_NAME(String iMAGE_NAME) {
IMAGE_NAME = iMAGE_NAME;
}

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID", unique = true, nullable = false)
private int ID;
@Column(name = "DATA", unique = false, nullable = false, length = 100000)
private byte[] data;
@Column(name = "IMAGE_NAME", unique = false, nullable = false, length = 100)
private String IMAGE_NAME;
@Transient

private List<MultipartFile> Files;

public List<MultipartFile> getFiles() {
return Files;
}

public void setFiles(List<MultipartFile> files) {
Files = files;
}

}

Controller :

package org.fileupload.controller;

import java.io.File;

import java.io.IOException;

import java.util.ArrayList;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.fileupload.dao.fileUploadDaoImpl;

import org.fileupload.model.FileuploadVO;

import org.fileupload.service.fileUploadServiceImpl;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.context.WebApplicationContext;

import org.springframework.web.context.support.WebApplicationContextUtils;

import org.springframework.web.multipart.MultipartFile;

@Controller

public class FileUploadController {

@RequestMapping(value = "/upload.htm", method = RequestMethod.POST)

public String SaveImage(

@ModelAttribute("uploadForm") FileuploadVO uploadForm,

Model map,HttpServletRequest request ) throws IllegalStateException, IOException {

WebApplicationContext context =WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());

fileUploadServiceImpl service=(fileUploadServiceImpl) context.getBean("fileuploadService");

fileUploadDaoImpl dao=(fileUploadDaoImpl) context.getBean("fileuploadDAO");

ResourceBundle rb = ResourceBundle.getBundle("resources/filePath"); //filePath is Property file
String saveDirectory = rb.getString("file.fileUploadPath");

List<MultipartFile> listFiles = uploadForm.getFiles();

List<String> fileNames = new ArrayList<String>();

if (null != listFiles && listFiles.size() > 0) {

for (MultipartFile multipartFile : listFiles) {

String fileName = multipartFile.getOriginalFilename();

if (!"".equalsIgnoreCase(fileName)) {

// Handle file content - multipartFile.getInputStream()

multipartFile

.transferTo(new File(saveDirectory + fileName));

fileNames.add(fileName);

uploadForm.setData(fileName.getBytes());

uploadForm.setIMAGE_NAME(fileName);

service.saveImage(uploadForm);

}

map.addAttribute("files", fileNames);

return "uploadfilesuccess";

}
@RequestMapping(value = "/download.htm", method = RequestMethod.GET)
public String download( @RequestParam("id") String id,
Model map,HttpServletRequest request,HttpServletResponse response) throws IllegalStateException, IOException {

System.out.println("id is : "+id);

WebApplicationContext context =WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());

fileUploadServiceImpl service=(fileUploadServiceImpl) context.getBean("fileuploadService");

FileuploadVO f = service.downloadImg(id);
response.setContentLength(f.getData().length);
response.setHeader("Content-Disposition","attachment; filename=\"" + f.getIMAGE_NAME() +"\"");

FileCopyUtils.copy(f.getData(), response.getOutputStream());

return null;

}

}

DAO LAYER

package org.fileupload.dao;

import org.fileupload.model.FileuploadVO;

public interface fileUploadDao {

public void saveImage(FileuploadVO fileupload);

public FileuploadVO downloadImg(String id);
}

package org.fileupload.dao;

import org.fileupload.model.FileuploadVO;

import org.springframework.orm.hibernate3.HibernateTemplate;

public class fileUploadDaoImpl implements fileUploadDao{

private HibernateTemplate template;

public fileUploadDaoImpl(HibernateTemplate template) {

this.template = template;

}

@Override

public void saveImage(FileuploadVO fileupload) {

template.save(fileupload);

}

public FileuploadVO downloadImg(String id)
{
// String query = "select * from trnimage where ID = ?";
FileuploadVO file = (FileuploadVO) template.getSessionFactory().openSession().load(FileuploadVO.class, new Integer(id));

return file;
}

}

SERVICE LAYER:

package org.fileupload.service;

import org.fileupload.model.FileuploadVO;

public interface fiileUploadService {

public void saveImage(FileuploadVO fileupload);
public FileuploadVO downloadImg(String id);

}

package org.fileupload.service;

import org.fileupload.dao.fileUploadDaoImpl;

import org.fileupload.model.FileuploadVO;

import org.springframework.beans.factory.annotation.Autowired;

public class fileUploadServiceImpl implements fiileUploadService{

@Autowired

private fileUploadDaoImpl fileuploadDAO;

@Override

public void saveImage(FileuploadVO fileupload) {

fileuploadDAO.saveImage(fileupload);

}
public FileuploadVO downloadImg(String id) {

return fileuploadDAO.downloadImg(id);

}
