ParameterMethodNameResolver, a MultiActionController method name resolver to map URL to method name via request parameter name, and the parameter name is customizable through the “paramName” property. 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. ParameterMethodNameResolver
With ParameterMethodNameResolver configured, and define the parameter name thought the “paramName” property:
<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.ParameterMethodNameResolver">
<property name="paramName" value="action"/>
</bean>
</property>
</bean>
</beans>
Now, the URL will map to the method name via the “action” request parameter name :
- /customer/*.htm?action=add –> add() method
- /customer/whatever.htm?action=add –> add() method
- /customer/*.htm?action=update –> update() method
- /customer/*.htm?action=delete –> delete() method
- /customer/*.htm?action=list –> list() method
P.S the “*” means any text.
Note
By default, MultiActionController is used the InternalPathMethodNameResolver to map URL to the corresponds method name.

Hi Mkyong!
I am getting error when I am trying to build this application. I am using netbeans and throws an error..
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property ‘methodNameResolver’ of bean class [controller.CustomerController]: Bean property ‘methodNameResolver’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Hi,
is your CustomerController extending MultiActionController?
