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.
