How to create HelloWorld Spring MVC Web application using Maven and Eclipse
In this blog post, I will be explaining how you can create a Spring MVC web application. In order to learn the Spring framework from scratch, you can enroll in this Spring Course.
Create a Project and And Maven Support
Step 1 – Follow the steps in this article to create a web project in Eclipse with Maven Support. You should see a project as follows:
Step 2 – Add the Maven Dependencies for Spring to the pom file as follows:
<dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency></dependencies>
Add Spring Configuration
Step 1 – Right-click on WebContent/WEB-INF –>New –> File
Step 2 – Type some name. The name should be of the format <name>-servlet.xml. Here, I have used learnjava-servlet.xml
Step 3 – Click “Finish”. This will create a file as follows:
Step 4 – Enter the following text and save:
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="com.learnjava.controller" /> <mvc:annotation-driven /> <mvc:default-servlet-handler /> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
Modify web.xml
Step 1 – Create web.xml (if it does not exist). Refer to this article
Step 2 – Update web.xml to include the Spring MVC Configuration. So add the following:
<servlet> <servlet-name>learnjava</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>learnjava</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
Add Code
Step 1 – Create a new controller class in src folder as follows:
Step 2 – Add the following code:
package com.learnjava.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;@Controllerpublic class HelloWorldController { @RequestMapping("/hello") public ModelAndView helloWorld() { System.out.println("In HelloWorldController"); String message = "<br><div style='text-align:center;'>" + "<h1>Hello World</h1></div><br><br>"; return new ModelAndView("hello", "message", message); }}
Step 3 – Create the WEB-INF/jsp folder as follows:
Step 3 – Enter folder name as “jsp”
Step 4 – Create hello.jsp
Step 5 – Add the following code:
<html><head>LearnJava SpringMVC Example</title></head><body>${message} <br> <br> <div style="font-family: verdana; padding: 10px; border-radius: 10px; font-size: 12px; text-align: center;"> Visit <a href="https://learnjava.co.in">LearnJava</a> to learn more Java stuff!!. </div></body></html>
Compile
Step 1 – Right Click on Project –> Run As –> Maven Build
Step 2 – If prompted, enter the goals as Clean –> Install
This will display a build success message as follows:
Test
You will need to have Tomcat setup in Eclipse. If you do not have Tomcat set up, refer to this blog post.
Step 1 – Right click on “Tomcat Server” at the bottom and click Add/Remove:
Step 2 – Select SpringMVCJSPDemo project and click “Add”:
Step 3 – Click on Finish.
Step 4 – Right click on “Tomcat” and click on “Start”
If the server starts successfully, you should see a message similar to the following in the console:
Step 5 – Open a browser and type http://localhost:8080/SpringMVCJSPDemo/hello. This will display the following:
