Spring MVC Error 405 Request method 'POST'

I think I have seen every post on the web about this topic but I cannot correct that bug :(

I have a Web App using Spring Security and Spring Mvc and I want to create a form to upload an image (you have to be logged to do that) but whatever the way I twist my code with what I find on forums, I have an Error 405 Request method 'POST' not supported when uploading a file

Here is my applicationContext.xml :

 <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans

                       http://www.springframework.org/schema/context/spring-context.xsd">


<context:component-scan base-package="com.meltdown.*" />
<context:annotation-config />

<bean id="userDAO" class="com.meltdown.bo.users.infra.impl.JdbcUserDAO">
    <property name="dataSource" ref="dataSource" />
 </bean>
<bean id="userService" class="com.meltdown.bo.users.application.service.impl.StandardUserService" />

 <bean id="barDAO" class="com.meltdown.bo.bars.infra.impl.JdbcBarDAO">
    <property name="dataSource" ref="dataSource" />

<bean id="barService" class="com.meltdown.bo.bars.application.service.impl.StandardBarService" />

 <bean id="newsDAO" class="com.meltdown.bo.news.infra.impl.JdbcNewsDAO">
    <property name="dataSource" ref="dataSource" />
 </bean>
<bean id="newsService" class="com.meltdown.bo.news.application.service.impl.StandardNewsService" />

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- one of the properties available; the maximum file size in bytes -->
<property name="maxUploadSize" value="100000"/>
</bean>
</beans>

my Controller :

@Controller
public class FileUploadController {
@RequestMapping(value="/bo/uploadImage", method = RequestMethod.GET)
public String uploadImage() {

    return "bo_uploadimage";
}

@RequestMapping(value="/bo/uploadImage", method = RequestMethod.POST)
public String uploadImage(@RequestParam(value = "file")FileUploadBean file, BindException errors, Map<String, Object> model) {

    System.out.println("#############################" + file);

    return "bo_uploadimage";
}
}



public class FileUploadBean{

private byte[] file;

public void setFile(byte[] file) {
    this.file = file;
}

public byte[] getFile() {
    return file;
}
}

jsp:

<html>
<head>
    <title>Upload a file please</title>
</head>
<body>
    <h1>Please upload a file</h1>
    <form method="post" action="/meltdown/bo/uploadImage" enctype="multipart/form-data">
        <input type="file" name="file"/>
        <input type="submit"/>
    </form>
</body>
</html>

I think the problem come from my controler and maybe because I mixed up Spring 4 annotations with Spring3 conf?

Thank's for your help!!

Edit mvc-dispatcher-servlet.xml

</bean>
</beans>

Ok so I finally find out the problem.

First, I used MultipartFile as mentionned in almost all tutorials and i used an @ModelAttribute to map this MultipartFile to my form. But it was not really the problem : I just cleaned up the implmentation to make it more standard.

Then, I discovered something wrong in the DEBUG logs :

20:58:38,370 DEBUG CsrfFilter:95 - Invalid CSRF token found for http://localhost:8080/meltdown/bo/createnews

and i used spring recommendation to correct it : (see spring security csrf doc)

There are two options to using CSRF protection with multipart/form-data. Each option has its tradeoffs.

Placing MultipartFilter before Spring Security

Include CSRF token in action

I used second option and placed ?${_csrf.parameterName}=${_csrf.token} at the end of my form's action url.

It works but I have to dig a bit what s under all that stuff... And to check what is really and if I need csrf.

Thank you everyone for your help
