Spring MVC - Mapping to .htm doesn't work - spring-mvc

Question

I want to crate a simple hello world following a tutorial step by step, but I think that missing something, because my code returns just a 404
Please, can you help me with what is wrong?
This is the Controller class
package com.companyname.springapp;
import java.io.IOException;
import java.util.Date;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
/**
* Created by cota on 22/12/15.
*/
#Controller
public class HelloController{
protected final Log logger = LogFactory.getLog(getClass());
#RequestMapping(value="/hello.htm",method = RequestMethod.GET)
public ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException {
String now = (new Date()).toString();
logger.info("Returning hello view with " + now);
return new ModelAndView("views/hello.jsp", "now", now);
}
}
This is the web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

</servlet>
<servlet-mapping>

</servlet-mapping>
This is the app-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>
This is a header file to include all the JSP files
<%# page session="false"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
And the index.jsp and hello.jsp have the next line
<%# include file="views/include.jsp" %>
It's my first question here and really admire all of you, sorry for my poor english!

I don`t think so you have not properly configured view resolver. so, please try the below links. It may be work for you.
Open your app-config.xml and add the below lines.
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/views/" p:suffix=".jsp" />
and modify the your controller as below.
#RequestMapping(value="/hello.htm",method = RequestMethod.GET)
public ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException {
String now = (new Date()).toString();
logger.info("Returning hello view with " + now);
return new ModelAndView("hello", "now", now);
}
I hope this will work for you..
