Maven + Spring web project not hitting controller

Question

[enter image description here][1][enter image description here][1]I am trying to create Maven + Spring web demo project. For this I created an index.jsp from where I am trying to hit controller with value as my name. But After running application even if I am getting index page, if I hit the hyper link to hit my controller, I am immediately getting The requested resource is not available. I am novice in maven and spring. Please help on this.

My Controller class is,

package web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {
String message = "Welcome to Spring MVC!";

@RequestMapping(value="/hello", method = RequestMethod.GET)
public ModelAndView showMessage(
        @RequestParam(value = "name", required = false, defaultValue = "World") String name) {
    System.out.println("in controller");

    ModelAndView mv = new ModelAndView("helloworld");
    mv.addObject("message", message);
    mv.addObject("name", name);
    return mv;
  }
}

I am not able to understand the specific reason for not hitting the controller. Kindly help on this. I am using JDK 1.7, Spring 3.2.8.Release and dynamic web module 2.5

My web.xml is,

and my Project Folder structure is, [TestMaven project folder structure][1]: https://i.stack.imgur.com/QV0pC.jpg

does this `System.out.println("in controller")` get printed .? — Saif, Feb 22 '16 at 11:20
look what i see that it is a copied project from some web sources I think. so please post a snap of directory structure .. — Vikrant Kashyap, Feb 22 '16 at 11:23
Yes it is copied but I checked every portion of it and tried to match it from google. But I can't seem to find the error. @ - Vikrant Kashyap — Gourab Banerjee, Feb 22 '16 at 12:44
index.jsp is loading by default. I didn't even mentioned it in any jsp. I think its directly loading from InternalResourceViewResolver mentioned in web.xml @ manish — Gourab Banerjee, Feb 22 '16 at 19:50

Try to update your dispatcher-servlet configuration to something like this:

<context:component-scan base-package="web.controller"/>

The use-default-filters documentation in the xsd says:

Indicates whether automatic detection of classes annotated with @Component, @Repository, @Service, or @Controller should be enabled. Default is "true".

I edited it thinking the code will work but it wasn't. Previously use-default-filters was not even mentioned. And also was there. It didn't work then. Its not working now – Gourab Banerjee Feb 22 '16 at 19:47
Can you post the directory structure of your project, so we know if the file is in the correct place. And can you post the content of your `web.xml` file. – W-S Feb 22 '16 at 22:21
I have updated my web.xml and attached image of project Folder. In views folder helloworld.jsp resides - @W-S – Gourab Banerjee Feb 23 '16 at 04:20
@W-S has provided the correct solution. Your annotation configuration is incorrect. I have copied your code on [Github](https://github.com/manish-in-java/stackoverflow-questions/tree/master/35552122) with the change suggested by @W-S. Check it out and run it as `mvn clean tomcat7:run`. Then launch a web browser at [localhost:8080](http://localhost:8080). Your controller will get executed when you click the link on the presented page as you expect. – manish Feb 23 '16 at 04:35
@GourabBanerjee your `web.xml`, the project structure and the location of files look right to me. And as confirmed by @manish, by just removing the `use-default-filters` your code should work as expected. – W-S Feb 23 '16 at 05:07
