Spring MVC with JSP allows you to build dynamic web pages where the controller processes requests, adds data to the model and then forwards it to a JSP page to render the final output. It's a clean and organized way to separate logic from presentation.
Step to implement Spring MVC with JSP
Step 1: Create the Project
- Eclipse IDE: File -> New -> Dynamic Web Project (check "Generate web.xml")
- IntelliJ: New -> Project > Maven -> Web App archetype
Step 2: Add Maven Dependencies
Add below dependecies in pom.xml file:
Java
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.7</version>
</dependency>
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
This file tells the servlet container how to load the Spring DispatcherServlet and which file has Spring configurations.
web.xml
Java
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>SampleMVC</display-name>
<!-- Load Spring Context -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Location of Spring application context -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<!-- Spring DispatcherServlet -->
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Servlet Mapping -->
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- Welcome file -->
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jsp</welcome-file> <!-- optional -->
</welcome-file-list>
</web-app>
Step 4: Create Spring Configuration file
This file initializes Spring MVC, scans your Java classes and sets up view resolution (JSP mapping) WebApplicationContext. And this contains the MVC-specific configurations including view-resolvers, datasource, messagesource, multipart-resolver (file-upload), etc.
mvc-dispatcher-servlet.xml
Java
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="...">
<!-- Scan all Java classes in this package for Spring annotations -->
<context:component-scan base-package="com.springsamples" />
<!-- Enable Spring MVC Annotations (@Controller, @GetMapping, etc.) -->
<mvc:annotation-driven />
<!-- Allow static content (CSS, JS, images) -->
<mvc:default-servlet-handler />
<!-- Configure JSP view resolver -->
<bean id="viewProvider" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
Step 5: Create the Controller
Java
package com.springsamples.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HomeController {
@GetMapping("/") public ModelAndView firstView()
{
// "greet" will map to greet.jsp
ModelAndView mav = new ModelAndView("greet");
mav.addObject(
"greeting",
"GeeksForGeeks Welcomes you to Spring!");
return mav;
}
}
Step 6: Create the JSP View.
Place this file inside: src/main/webapp/greet.jsp
greet.jsp
Java
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" isELIgnored="false" %>
<!DOCTYPE html PUBLIC "- Transitional
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
<title>Start Spring MVC</title>
</head>
<body>
<h1>Start here</h1>
${greeting}
</body>
</html>
