@RequestMapping(“/welcome”)

<h1>Message : ${message}</h1>
</body>
</html>

Now configure  applicationContext.xml and web.xml

Step 3:        applicationContext.xml

<beans xmlns=”http://www.springframework.org/schema/beans”
xmlns:context=”http://www.springframework.org/schema/context”
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd”>

<context:annotation-config />

<context:component-scan base-package=”com.javaproficiency.demo” />

<bean
class=”org.springframework.web.servlet.view.InternalResourceViewResolver”>
<property name=”prefix”>
<value>/WEB-INF/</value>
</property>
<property name=”suffix”>
<value>.jsp</value>
</property>
</bean>

</beans>

Step 4: web.xml

<web-app id=”WebApp_ID” version=”2.4″
xmlns=”http://java.sun.com/xml/ns/j2ee”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd”>

<display-name>Spring MVC Application</display-name>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<servlet>
<servlet-name>hellomvc2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>hellomvc2</servlet-name>
<url-pattern>/web/*</url-pattern>
</servlet-mapping>

</web-app>

step 5:  pom.xml

<project xmlns=”http://maven.apache.org/POM/4.0.0″ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd”>
