Spring MVC - Bean Name Url Handler Mapping Example

The following example shows how to use Bean Name URL Handler Mapping using the Spring Web MVC Framework. The BeanNameUrlHandlerMapping class is the default handler mapping class, which maps the URL request(s) to the name of the beans mentioned in the configuration.
<beans>
   <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name = "prefix" value = "/WEB-INF/jsp/"/>
      <property name = "suffix" value = ".jsp"/>
   </bean>

   <bean class = "org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

   <bean name = "/helloWorld.htm" 
      class = "com.tutorialspoint.HelloController" />

   <bean name = "/hello*" 
      class = "com.tutorialspoint.HelloController" /> 

   <bean name = "/welcome.htm"
      class = "com.tutorialspoint.WelcomeController"/>   
</beans>
For example, using the above configuration, if URI
/helloWorld.htm or /hello{any letter}.htm is requested, DispatcherServlet will forward the request to the HelloController.
/helloWorld.htm or /hello{any letter}.htm is requested, DispatcherServlet will forward the request to the HelloController.
/welcome.htm is requested, DispatcherServlet will forward the request to the WelcomeController.
/welcome.htm is requested, DispatcherServlet will forward the request to the WelcomeController.
/welcome1.htm is requested, DispatcherServlet will not find any controller and server will throw 404 status error.
/welcome1.htm is requested, DispatcherServlet will not find any controller and server will throw 404 status error.
To start with, let us have a working Eclipse IDE in place and consider the following steps to develop a Dynamic Form based Web Application using the Spring Web Framework.
package com.tutorialspoint;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HelloController extends AbstractController{
  
   @Override
   protected ModelAndView handleRequestInternal(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("hello");
      model.addObject("message", "Hello World!");
      return model;
   }
}
package com.tutorialspoint;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class WelcomeController extends AbstractController{
  
   @Override
   protected ModelAndView handleRequestInternal(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("welcome");
      model.addObject("message", "Welcome!");
      return model;
   }
}
<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 = "

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

   <bean class = "org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

   <bean name = "/helloWorld.htm" 
      class = "com.tutorialspoint.HelloController" />

   <bean name = "/hello*" 
      class = "com.tutorialspoint.HelloController" /> 

   <bean name = "/welcome.htm"
      class = "com.tutorialspoint.WelcomeController"/>   
</beans>
<%@ page contentType = "text/html; charset = UTF-8" %>
<html>
   <head>
      <title>Hello World</title>
   </head>
   <body>
      <h2>${message}</h2>
   </body>
</html>
<%@ page contentType = "text/html; charset = UTF-8" %>
<html>
   <head>
      <title>Welcome</title>
   </head>
   <body>
      <h2>${message}</h2>
   </body>
</html>
Once you are done with creating source and configuration files, export your application. Right click on your application, use Export → WAR File option and save the TestWeb.war file in the Tomcat's webapps folder.
Now, start your Tomcat server and make sure you are able to access other webpages from the webapps folder by using a standard browser. Try a URL − http://localhost:8080/TestWeb/helloWorld.htm and we will see the following screen, if everything is fine with the Spring Web Application.
Try a URL − http://localhost:8080/TestWeb/hello.htm and we will see the following screen, if everything is fine with the Spring Web Application.
Try a URL http://localhost:8080/TestWeb/welcome.htm and we will see the following screen, if everything is fine with the Spring Web Application.
Try a URL http://localhost:8080/TestWeb/welcome1.htm and we will see the following screen, if everything is fine with the Spring Web Application.
