servlet-mapping定义所有以/page/开头的url��h��都会被spring 的DispatcherServlet处理转发。默认情况下DispatcherServlet会读�?lt;servlet-name>-servlet.xml文�g的配�|�信息初始化�Q�该文�g中urlMapping的定义决定当前请求�{发给哪个controller来处理�?br />
Step2�Q?font size="2">定义/WEB-INF/springMVC-servlet.xml

xml version="1.0" encoding="UTF-8"?>
DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

    <bean id="controller" class="com.controller.IndexController">

urlMapping定义/controller/开头的url��h��由名字�ؓcontroller的控制器来处理，因�ؓ是多动作处理器，所以要定义MethodNameResolver来告诉springMVC应该调用controller的哪个方法，�q�里用的�?font color="#0000ff">InternalPathMethodNameResolver�Q�该�Ҏ��名解释器会把整个URL中最后一�?font color="#0000ff">"/"和最后一�?font color="#0000ff">"."之间的部分作��调用的方法名�?/font>

Step3�Q?font size="2">定义controller�c�dƈ�l�承MultiActionController

package com.controller;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.ServletException;
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 IndexController extends MultiActionController {

    public ModelAndView method1(HttpServletRequest request,
            HttpServletResponse respnose) throws ServletException, IOException {
        Map model = new HashMap();
        model.put("message", "你调用的是方法１");
        return new ModelAndView("/index.jsp", "model", model);
    }

    public ModelAndView method2(HttpServletRequest request,
            HttpServletResponse respnose) throws ServletException, IOException {
        Map model = new HashMap();
        model.put("message", "你调用的是方法２");
        return new ModelAndView("/index.jsp", "model", model);
    }
}

通过配置文�g�Q�访问上面这个controller中某个方法的url即�ؓ�Q?/font>localhost:8080/page/controller/�Ҏ��?br />

Step4�Q?index.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>

DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>head>
<body>
<c:out value="${model.message}"/>
body>
html>

因�ؓInternalPathMethodNameResolver�Ҏ��名解释器会把整个URL中最后一�?font color="#0000ff">"/"和最后一�?font color="#0000ff">"."之间的部分作��调用的方法名�Q�所以你可以在这个URL后面加�Q意文件格式的后缀�Q�比如：
localhost:8080/page/controller/method1.jsp
�?br />localhost:8080/page/controller/method2.html
很爽吧，和真实的URL地址一栗��?/font>

另：开发环境：MyEclipse5.0M2+tomcat5.5
　　需要用到spring.jar和jstl.jar两个包�?br />
附：源代码下�?/a>
