PropertiesMethodNameResolver, a flexible MultiActionController method name resolver, to define the mapping between the URL and method name explicitly. See following example :

1. MultiActionController

A MultiActionController example.

package com.mkyong.common.controller;

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 CustomerController extends MultiActionController{
	
	public ModelAndView add(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
		
		return new ModelAndView("CustomerPage", "msg","add() method");
			
	}
	
	public ModelAndView delete(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
			
		return new ModelAndView("CustomerPage", "msg","delete() method");
				
	}
	
	public ModelAndView update(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
			
		return new ModelAndView("CustomerPage", "msg","update() method");
				
	}
	
	public ModelAndView list(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
				
		return new ModelAndView("CustomerPage", "msg","list() method");
					
	}
	
}

2. PropertiesMethodNameResolver

With PropertiesMethodNameResolver, you can map whatever URL name to corresponds method name easily :

<beans ...>

 <bean 
  class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
    
 <bean class="com.mkyong.common.controller.CustomerController">
   <property name="methodNameResolver">
    <bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
      <property name="mappings">
	<props>
	   <prop key="/customer/a.htm">add</prop>
	   <prop key="/customer/b.htm">update</prop>
	   <prop key="/customer/c.htm">delete</prop>
	   <prop key="/customer/d.htm">list</prop>
	   <prop key="/customer/whatever.htm">add</prop>
	</props>
       </property>
     </bean>
    </property>
  </bean>

</beans>

Now, the URL will map to the method name in the following pattern :

1. /customer/a.htm –> add() method
2. /customer/b.htm –> update() method
3. /customer/c.htm –> delete() method
4. /customer/d.htm –> list() method
5. /customer/whatever.htm –> add() method
