The following example show how to write a simple web based Hello
World application using Spring MVC framework. To start with it, let us
have working Eclipse IDE in place and follow the following steps to
develope a Dynamic Web Application using Spring Web Framework:
HelloController.java
Now start your Tomcat server and make sure you are able to access other web pages from webapps folder using a standard browser. Now try to access the URL http://localhost:8080/HelloWeb/hello and if everything is fine with your Spring Web Application, you should see the following result:
You should note that in the given URL, HelloWeb is the application name and hello
is the virtual subfolder which we have mentioned in our controller
using @RequestMapping("/hello"). You can use direct root while mapping
your URL using @RequestMapping("/"), in this case you can access the same page using short URL http://localhost:8080/HelloWeb/ but it is advised to have different functionalities under different folders.
| Step | Description |
|---|---|
| 1 | Create a Dynamic Web Project with a name HelloWeb and create a package com.tutorialspoint under the src folder in the created project. |
| 2 | Drag and drop below mentioned Spring and other libraries into the folder WebContent/WEB-INF/lib. |
| 3 | Create a Java class HelloController under the com.tutorialspoint package. |
| 4 | Create Spring configuration files web.xml and HelloWeb-servlet.xml under the WebContent/WEB-INF folder. |
| 5 | Create a sub-folder with a name jsp under the WebContent/WEB-INF folder. Create a view file hello.jsp under this sub-folder. |
| 6 | The final step is to create the content of all the source and configuration files and export the application as explained below. |
package com.tutorialspoint; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.ui.ModelMap; @Controller @RequestMapping("/hello") public class HelloController{ @RequestMapping(method = RequestMethod.GET) public String printHello(ModelMap model) { model.addAttribute("message", "Hello Spring MVC Framework!"); return "hello"; } }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> <servlet> <servlet-name>HelloWeb</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>HelloWeb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>HelloWeb-servlet.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:component-scan base-package="com.tutorialspoint" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>hello.jsp
<%@ page contentType="text/html; charset=UTF-8" %> <html> <head> <title>Hello World</title> </head> <body> <h2>${message}</h2> </body> </html>Finally, following is the list of Spring and other libraries to be included in your web application. You simply drag these files and drop them in WebContent/WEB-INF/lib folder.
- servlet-api-x.y.z.jar
- commons-logging-x.y.z.jar
- spring-aop-x.y.z.jar
- spring-beans-x.y.z.jar
- spring-context-x.y.z.jar
- spring-core-x.y.z.jar
- spring-expression-x.y.z.jar
- spring-webmvc-x.y.z.jar
- spring-web-x.y.z.jar
Now start your Tomcat server and make sure you are able to access other web pages from webapps folder using a standard browser. Now try to access the URL http://localhost:8080/HelloWeb/hello and if everything is fine with your Spring Web Application, you should see the following result:
You should note that in the given URL, HelloWeb is the application name and hello
is the virtual subfolder which we have mentioned in our controller
using @RequestMapping("/hello"). You can use direct root while mapping
your URL using @RequestMapping("/"), in this case you can access the same page using short URL http://localhost:8080/HelloWeb/ but it is advised to have different functionalities under different folders.
