我们都知道，servlet代码一般来说只能在一个servlet中做判断去实现一个servlet响应多个请求，

但是springMVC的话还是比较方便的，主要有两种方式去实现一个controller里能响应多个请求

第一种：继承MultiActionController类，这种方法已经废弃了，但是也能用

项目结构

具体配置

       
             
      	
              
         
             
          
              
                   
                
           
      	
      		
       
        
         /WEB-INF/pages
        
       		
       
        
         .jsp
        
       	
      
     

　

web.xml没改　

     
            
      
       Spring MVC Application
            
      
               
       
        mvc-dispatcher
               
       
        org.springframework.web.servlet.DispatcherServlet
               
       
        1
           
            
      
               
       
        mvc-dispatcher
               
       
        /
           
            
      
               
       
        contextConfigLocation
               
       
        classpath*:mvc-dispatcher-servlet.xml
           
            
      
               
       
        org.springframework.web.context.ContextLoaderListener
           
        
     

hello.jsp　

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>              	
     	
     	
         	
     	
     	
               This is my JSP page. 
      本次调用方法是${message }  

控制器

package controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import net.sf.json.JSONObject;import org.springframework.stereotype.Controller;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.multiaction.MultiActionController;@SuppressWarnings("deprecation")@Controllerpublic class MyController extends MultiActionController {	public ModelAndView add(HttpServletRequest request,            HttpServletResponse response) {        System.out.println("----add----");        return new ModelAndView("/hello", "message", "add");    }	public ModelAndView del(HttpServletRequest request,            HttpServletResponse response) {        System.out.println("----del----");        return new ModelAndView("/hello", "message", "del");    }		//接收单个字符串	public void update(HttpServletRequest request,            HttpServletResponse response){		String name=request.getParameter("name");		System.out.println("name:"+name);	}}

　　

访问方式　

http://localhost:8080/MyWeb/pay?cmd=update&name=xxxx

后台输出了

name:xxxx

输入

http://localhost:8080/MyWeb/pay?cmd=add

前台显示为

This is my JSP page. 本次调用方法是add

　　

第二种：就是最常用的用注解了　　

spring配置

       
           
        
      	
      		
       
        
         /WEB-INF/pages
        
       		
       
        
         .jsp
        
       	
      
     

　　

控制器　

package 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@RequestMapping("/pay")public class MyController{	@RequestMapping("/add")	public ModelAndView add(HttpServletRequest request,            HttpServletResponse response) {        System.out.println("----add----");        String name=request.getParameter("name");        System.out.println(name);        return new ModelAndView("/hello", "message", "add");    }	@RequestMapping("/del")	public ModelAndView del(HttpServletRequest request,            HttpServletResponse response) {        System.out.println("----del----");        String name=request.getParameter("name");        System.out.println(name);        return new ModelAndView("/hello", "message", "del");    }}

　　

调用方式

http://localhost:8080/MyWeb1/pay/add

前台结果

This is my JSP page. 本次调用方法是add
