Spring MVC MultiActionController annotation example

In this tutorial, we show you how to develop a Spring MVC annotation-based

MultiActionController

, by using

@RequestMapping

.

In XML-based

MultiActionController

, you have to configure the method name resolver (

InternalPathMethodNameResolver

,

PropertiesMethodNameResolver

or

ParameterMethodNameResolver

) to map the URL to a particular method name. But, life is more easier with annotation support, now you can use

@RequestMapping

annotation as a method name resolver, which used to map URL to a particular method.

To configure it, define

@RequestMapping

with mapping URL above the method name.

package com.mkyong.common.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class CustomerController{

@RequestMapping("/customer/add.htm")
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response) throws Exception {

return new ModelAndView("CustomerAddView");

}

@RequestMapping("/customer/delete.htm")
public ModelAndView delete(HttpServletRequest request,
HttpServletResponse response) throws Exception {

return new ModelAndView("CustomerDeleteView");

}

@RequestMapping("/customer/update.htm")
public ModelAndView update(HttpServletRequest request,
HttpServletResponse response) throws Exception {

return new ModelAndView("CustomerUpdateView");

}

@RequestMapping("/customer/list.htm")
public ModelAndView list(HttpServletRequest request,
HttpServletResponse response) throws Exception {

return new ModelAndView("CustomerListView");

}
}

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

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

Note

In Spring MVC, this

@RequestMapping

is always the most flexible and easy to use mapping mechanism.
