Video Tutorial : Spring MVC Example

Step 1: Create a hello controller

HelloController.java

package com.javaproficiency.demo;

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

@Controller
@RequestMapping("/welcome")
public class HelloController {

    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {

        model.addAttribute("message", "Spring MVC Hello World");
        return "hello";

    }

}

Step 2: hello.jsp

<html>
<body>
    <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
