本文展示了如何通过使用@RequestMapping注解在SpringMVC中开发基于注解的多动作控制器，简化了URL到特定方法名的映射过程。通过配置@RequestMapping，可以将URL直接映射到相应的动作方法，使开发过程更加灵活和容易。

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
