Introduction to Spring MVC Framework

1. Spring MVC Controller

SpringMVCController.java

package javabeat.net.spring.controller;

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

@Controller
@RequestMapping("/springtest")
public class SpringMVCController {

    @RequestMapping(value="/redirectTest", method = RequestMethod.GET)
    public String redirectTest() {
        //some stuff here
        return "redirect:/springtest/redirectedUrl";
    }

    @RequestMapping(value="/redirectedUrl", method = RequestMethod.GET)
    public String redirection(Model model) {
        //some stuff here
    	model.addAttribute("msg", "Spring Redirection Test");
        return "hello";
    }
}

2. Views

hello.jsp

<html>
<body>
	<h1>JavaBeat Spring MVC Examples</h1>
	<h2>Spring MVC Examples : ${msg}</h2>
</body>
</html>

3. Spring Configurations

spring-dispatcher-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:websocket="http://www.springframework.org/schema/websocket"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context
		http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/websocket
        http://www.springframework.org/schema/websocket/spring-websocket-4.0.xsd">

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

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

4. Web Deployment Descriptor

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>Spring MVC 4.0 Web Application</display-name>
	<servlet>
		<servlet-name>spring-dispatcher</servlet-name>
		<servlet-class>
			org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>
