Como fazer upload de imagens, mas sem salvar no banco de dados, salvando elas numa pasta.

Como faço isso??

Procura por commons upload

#3

Cara fiz um exemplo simples usando o commons-fileupload sugerido pelo colega, é necessário para fazer o parser da requisição! É bem simples, porém é para fins didáditos!

Segue

import javax.servlet.http.*;
import java.util.List;
import org.apache.commons.fileupload.*;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import java.io.*;
import java.nio.channels.FileChannel;



public class FileUploadServlet extends HttpServlet {

	public void doPost(HttpServletRequest req, HttpServletResponse res) throws IOException{
	
		try {

			FileItemFactory factory = new DiskFileItemFactory();
			ServletFileUpload upload = new ServletFileUpload(factory);
			List items = upload.parseRequest(req);
			
			FileItem fileItem = (FileItem) items.get(0);
			byte[] content = fileItem.get();
			
			
			String fileName = fileItem.getName();
			File file = new File("c:/temp/"+fileName);
			FileOutputStream fos = new FileOutputStream(file);
			fos.write(content);
			fos.flush();
			fos.close();
			
			
			System.out.println(items.size());
		
		} catch (FileUploadException ex) {
			ex.printStackTrace();
		}
		
	}
}
<html>
	<body>
		<form method="post" action="FileUpload" enctype="multipart/form-data">
			<input type="file" name="arquivo" />
			<input type="submit" value="Enviar" />
		</form>
	</body>
</html>
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

    <servlet>
        <servlet-name>FileUpload</servlet-name>
        <servlet-class>FileUploadServlet</servlet-class>
    </servlet>

	<servlet-mapping>
		<servlet-name>FileUpload</servlet-name>
		<url-pattern>/FileUpload</url-pattern>		
	</servlet-mapping>
</web-app>

E pronto :d

Qualquer dúvida é só postar!
