Spring MVC MultiActionController example

In Spring MVC application,

MultiActionController

is used to group related actions into a single controller, the method handler have to follow below signature :

public (ModelAndView | Map | String | void) actionName(
HttpServletRequest, HttpServletResponse [,HttpSession] [,CommandObject]);

1. MultiActionController

See 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");

}

}

With

ControllerClassNameHandlerMapping

configured.

<beans ...>

<bean
class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />

<bean class="com.mkyong.common.controller.CustomerController" />

</beans>

2. Mapping Examples

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

CustomerController –> /customer/*
/customer/add.htm –> add()
/customer/delete.htm –> delete()
/customer/update.htm –> update()
/customer/list.htm –> list()

3.

InternalPathMethodNameResolver

The

InternalPathMethodNameResolver

is the default

MultiActionController

implementation to map URL to method name. But, you are still allow to add

prefix

or

suffix

to the method name :

<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.InternalPathMethodNameResolver">
<property name="prefix" value="test" />
<property name="suffix" value="Customer" />
</bean>
</property>
</bean>
</beans>

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

CustomerController –> /customer/*
/customer/add.htm –> testaddCustomer()
/customer/delete.htm –> testdeleteCustomer()
/customer/update.htm –> testupdateCustomer()
/customer/list.htm –> testlistCustomer()
