Spring MVC - Simple Url Handler Mapping Example

The following example shows how to use Simple URL Handler Mapping using the Spring Web MVC framework. The SimpleUrlHandlerMapping class helps to explicitly-map URLs with their controllers respectively.
<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.SimpleUrlHandlerMapping">
      <property name = "mappings">
         <props>
            <prop key = "/welcome.htm">welcomeController</prop>		   
            <prop key = "/helloWorld.htm">helloController</prop>
         </props>
      </property>
   </bean>

   <bean id = "helloController" class = "com.tutorialspoint.HelloController" />

   <bean id = "welcomeController" class = "com.tutorialspoint.WelcomeController"/>  
</beans>
For example, using above configuration, if URI
/helloWorld.htm is requested, DispatcherServlet will forward the request to the HelloController.
/helloWorld.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.
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"

   <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.SimpleUrlHandlerMapping">
      <property name = "mappings">
         <props>
            <prop key = "/welcome.htm">welcomeController</prop>		   
            <prop key = "/helloWorld.htm">helloController</prop>
         </props>
      </property>
   </bean>

   <bean id = "helloController" class = "com.tutorialspoint.HelloController" />

   <bean id = "welcomeController" 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 the Export → WAR File option and save your TestWeb.war file in 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/welcome.htm and you should see the following result if everything is fine with your Spring Web Application.
