Spring MVC - Properties Method Name Resolver Example

The following example shows how to use the Properties Method Name Resolver method of a Multi Action Controller using Spring Web MVC framework. The MultiActionController class helps to map multiple URLs with their methods in a single controller respectively.
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.multiaction.MultiActionController;

public class UserController extends MultiActionController{
	
   public ModelAndView home(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Home");
      return model;
   }

   public ModelAndView add(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Add");
      return model;
   }

   public ModelAndView remove(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Remove");
      return model;
   }
}
<bean class = "com.tutorialspoint.UserController">
   <property name = "methodNameResolver">
      <bean class = "org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
         <property name = "mappings">
            <props>
               <prop key = "/user/home.htm">home</prop>
               <prop key = "/user/add.htm">add</prop>
               <prop key = "/user/remove.htm">update</prop>	  
            </props>
         </property>
      </bean>
   </property>
</bean>
For example, using the above configuration, if URI −
/user/home.htm is requested, DispatcherServlet will forward the request to the UserController home() method.
/user/home.htm is requested, DispatcherServlet will forward the request to the UserController home() method.
/user/add.htm is requested, DispatcherServlet will forward the request to the UserController add() method.
/user/add.htm is requested, DispatcherServlet will forward the request to the UserController add() method.
/user/remove.htm is requested, DispatcherServlet will forward the request to the UserController remove() method.
/user/remove.htm is requested, DispatcherServlet will forward the request to the UserController remove() method.
To start with it, 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.

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class UserController extends MultiActionController{
	
   public ModelAndView home(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Home");
      return model;
   }

   public ModelAndView add(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Add");
      return model;
   }

   public ModelAndView remove(HttpServletRequest request,
      HttpServletResponse response) throws Exception {
      ModelAndView model = new ModelAndView("user");
      model.addObject("message", "Remove");
      return model;
   }
}

   <head>
      <title>Hello World</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 Tomcat's webapps folder.
Now, start your Tomcat server and make sure you are able to access other webpages from the webapps folder using a standard browser. Now, try a URL − http://localhost:8080/TestWeb/user/add.htm and we will see the following screen, if everything is fine with the Spring Web Application.
