You are missing InternalResourceViewResolver bean in your telusko-servlet.xml

<!-- Define Spring MVC view resolver -->
<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".jsp" />
</bean>

Also its good practice to put your jsp pages in WEB-INF/view folder not outside of it. After adding that bean you do not return display.jsp

Your controller method should look like

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

Also it would be wise to avoid versions in your bean xml, if above does not help try using something like

<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"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"   
xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx.xsd">

You can call "/addController/add" like this

@Controller
@RequestMapping("/addController ")
public class AddController {
    @RequestMapping("/add")
    public String add() {
        return "display";
    }
}

It Helps Me

I have just created few changes and i succesfully remove the HTTP 404 Error even after adding RequestMapping Annotation

I have just move my packageand classes into the src/main/java and not into the src/main/resources which i have to created manually, and that should resolve the Mapping error.
