Spring MVC PropertiesMethodNameResolver example

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 :

    /customer/a.htm –> add() method    /customer/b.htm –> update() method    /customer/c.htm –> delete() method    /customer/d.htm –> list() method    /customer/whatever.htm –> add() method

Note
By default, MultiActionController is used the InternalPathMethodNameResolver to map URL to the corresponds method name.
