File Upload with PUT request

I'm working on file upload handling in server side. I'm using the code posted here. I modified the FileCommand Class code to the following

import org.springframework.web.multipart.MultipartFile;

public class FileUploadCommand {

private MultipartFile file;

public void setFile(MultipartFile file) {
    this.file=file;
}

public MultipartFile getFile() {
    return this.file;
} }

and the dispatcher-servlet.xml

<mvc:annotation-driven/>

<context:component-scan base-package="fileupload"/>

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/api/file/*"/>
            <bean id="fileUploadHandlerInterceptor" class="fileupload.FileUploadHandlerInterceptor">
                 <constructor-arg index="0" ref="putServletFileUpload" />
            </bean>
    </mvc:interceptor>
</mvc:interceptors>



<bean name="putServletFileUpload" class="fileupload.PutServletFileUpload">

    <constructor-arg index="0">
    <bean class="org.apache.commons.fileupload.disk.DiskFileItemFactory" />
    </constructor-arg>
</bean>

The problem is that the HandlerInterceptor which is FileUploadHandlerInterceptor were not called when I tested the application. Could anyone help me to find out the cause of this problem.
