request mapping is not taking me to the desired page, its showing error 404

Question

I am a spring beginner, I used controller and request mapping to go to some java file from index.jsp but its showing 404 Error. I am putting right urlmapping and requestmapping and controllers as I saw in a spring tutorial. I have tried including more dependencies, changing the code as I saw someplace else, but nothing working. Please help me with this code. Thanks in Advance

index.jsp:

    <html>
    <body>
    <form action="add">
    <input type="text" name="t1"><br>
    <input type="text" name="t2"><br>
    <input type="submit">
    </form>
    </body>
    </html>

web.xml:

    <!DOCTYPE web-app PUBLIC
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
         "http://java.sun.com/dtd/web-app_2_3.dtd" >

      </servlet-mapping>

AddController.java

    package garg.bhoomika;

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;

    @Controller
    public class AddController 
    {
    @RequestMapping("/add")
    public void add()
    {
        System.out.println("I am here");
    }

    }

Error:

org.springframework.web.servlet.PageNotFound noHandlerFound WARNING: No mapping found for HTTP request with URI [/SpringMVC/add] in DispatcherServlet with name 'bhoomika'

For now you should use <mvc:annotation-driven/> in your spring confuguration file to enable MVC configuration as described in official doc
Try to replace entry <context:annotation-config> to <mvc:annotation-driven/>.
And if you want to go to your index.jsp you should change method add() so that it returned view name as a String:

 @RequestMapping("/add")
    public String add() {
        return "index";
    }

Also you can see the exhaustive and descriptive answer to similar question this. It'll be useful.
