Spring Web application displaying HTTP Status 404 -

Hi I know this question has been asked and answered many many times..I checked various question on stackoverflow and on other web pages but still unable to find the solution

I am vert much beginner to Spring MVC.

I am trying to create a simple HelloWorld Program using Spring MVC- Controller.

I have written the following code, but its giving me HTTP Status 404 when i try to access http://localhost:5151/SpringMaven/

This is my project hierarchy

enter image description here

Web.xml

 <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

Spring Configuration File 

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

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

Controller

@Controller
public class HelloController {


    @RequestMapping("/welcome")
    public ModelAndView helloWorld() {

        String message = "Hello World";
        return new ModelAndView("welcome", "message", message);
    }
}

Add those line in your dispatcher-servlet.

<context:component-scan base-package="com.evantage"/>
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

Add those line in web.xml

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Let me know what is the output.

UPDATE: In dispatcher-servlet.xml add those line in <bean> tag.

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.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-3.0.xsd"

Try with this web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.evantage</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

And enable autowire in your dispatcher:

<!-- Enable autowire -->
<context:annotation-config />

Try to add this to Spring Configuration File:

 <mvc:annotation-driven>

And add this in schema in top:

 http://www.springframework.org/schema/mvc

Because you try to access /SpringMaven URL, but you've bound your controller action to /welcome path.

Either change @RequestMapping annotation to use expected URL, or go to http://localhost:5151/welcome.

-edit-

And make sure your controller is registred as a service - either register by hand in Spring configuration or enable MVC annotations scanning so Spring can auto-find the @Controller-annotated service.
