Upload file with Spring MVC

Question

i am trying to upload a file with spring, but when i run the app, i get : WARN : org.springframework.web.servlet.PageNotFound - Request method 'GET' not supported

My Cotroller class is:

package com.tu.Main;

@Controller
public class FileUpload {



private static final Logger logger = LoggerFactory
        .getLogger(FileUpload.class);

/**
 * Upload single file using Spring Controller
 */
@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();

            logger.info("Server File Location="
                    + serverFile.getAbsolutePath());

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

/**
 * Upload multiple file using Spring Controller
 */
@RequestMapping(value = "/uploadMultipleFile", method = RequestMethod.POST)
public @ResponseBody
String uploadMultipleFileHandler(@RequestParam("name") String[] names,
        @RequestParam("file") MultipartFile[] files) {

    if (files.length != names.length)
        return "Mandatory information missing";

    String message = "";
    for (int i = 0; i < files.length; i++) {
        MultipartFile file = files[i];
        String name = names[i];
        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();

            logger.info("Server File Location="
                    + serverFile.getAbsolutePath());

            message = message + "You successfully uploaded file=" + name
                    + "<br />";
        } catch (Exception e) {
            return "You failed to upload " + name + " => " + e.getMessage();
        }
    }
    return message;
}
}

upload.jsp

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

<%@ page session="false" %>

<html>

<head>

<title>Upload File Request Page</title>

</head>

<body>


<form method="POST" action="uploadFile" enctype="multipart/form-data">
    File to upload: <input type="file" name="file"><br /> 
    Name: <input type="text" name="name"><br /> <br /> 
    <input type="submit" value="Upload"> Press here to upload the file!
</form>

My servlet-context.xml is:

<beans:beans xmlns="http://www.springframework.org/schema/mvc"

<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->

    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" />
</beans:bean>

<beans:bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<beans:property name="maxUploadSize" value="100000" />
</beans:bean>

    <context:component-scan base-package="com.tu.Main" />

</beans:beans>

Can someone helps me?? Thank you very much in advance!

You didn't write the Get method for getting the input page. You miss something like following:

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