Maven: Add Spring dependencies and Spring MVC your project

To enable Spring and Spring MVC modules in your maven project, follow the steps below

1: Add Spring related dependencies. The dependencies below will get all the rest of the transitive dependencies.

          <!-- Exclude Commons Logging in favor of SLF4j -->

The org.springframework.version property is set to 3.0.3.RELEASE:

2. Setup Dispatcher Servlet in your web.xml:

The Spring MVC requires setting the dispatcher servlet in web.xml. Below we are loading the /WEB-INF/sprin/app-config.xml (the main Spring application configuration file for the project) while instantiating the Dispatcher Servlet at application start up time i.e. when the server is starting up.

NOTE: You can name your application config with any name of your liking. Just make sure it is correctly referenced in Dispatcher Servlet setting in web.xml.


3. The context config location points to the spring application config file for the application (app-config.xml).

There are 2 things of note here:

a. The com.mayabansi.webappdemo will be scanned for classes annotated with @Controller, @Resources, @Component, @Service etc.
b. The mvc-config.xml, that holds the MVC configuration settings is imported.

<!-- Scans the classpath of this application for @Components to deploy as beans -->  
<context:component-scan base-package="com.mayabansi.webappdemo">  
      <!-- Import MVC related configuration -->
       <import resource="mvc-config.xml"/>        
4. The MVC config file has Spring MVC related configuration settings:
<!-- Configures the @Controller programming model -->  
    <!-- Forwards requests to the "/" resource to the "welcome" view -->
    <mvc:view-controller path="/" view-name="welcome">
        <!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/views/">
            <property name="suffix" value=".jsp">
