Page Not Found if <mvc:annotation-driven/> is Removed

[protocyber]

Hi all, I'm new to Spring Framework and using Spring for my current web project.

I would like to ask, is <mvc:annotation-driven/> needed when we use @Controller and @RequestMapping annotation ?

Because if I delete those line from my context-config.xml, I got this error message:

HTTP Status 404 - 

The requested resource () is not available.

And the Apache log shows this message:

05:38:48,021  WARN "http-bio-8084"-exec-11 servlet.PageNotFound:1057 - No mapping found for HTTP request with URI [/Edunesia/Beranda] in DispatcherServlet with name 'SpringDispatcherServlet'

I'm really confused because many references out there
say that <mvc:annotation-driven/> is only needed if we want to use certain feature, such as Jackson for JSON.

Here is my web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app metadata-complete="true" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>

context-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

          http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

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

    <mvc:view-controller path="/" view-name="welcome"/>
          
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

The controller which has the problem:

package net.edunesia.controller;

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

@Controller
@RequestMapping("/Beranda")
public class Beranda {

    @RequestMapping(method = RequestMethod.GET)
    public String get() {
        return "beranda";
    }
}

I don't create /WEB-INF/SpringDispatcherServlet.xml
because I set /WEB-INF/spring/context-config.xml for contextConfigLocation
as DispatcherServlet init parameter.

Thank you.

I've found the problem.

It is caused by

<mvc:view-controller path="/" view-name="welcome"/>

So I remove those line from my configuration.
