springMVC 多方法controller

1. 新建web project

2. 加入jar包

3. 写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <servlet>
  	<servlet-name>springMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath*:config/spring-servlet.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
</web-app>

4. 新建config包, 新建spring-servlet.xml　　文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"    
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"    
    xmlns:context="http://www.springframework.org/schema/context"    
    xmlns:mvc="http://www.springframework.org/schema/mvc"    
    xsi:schemaLocation="     
           http://www.springframework.org/schema/beans     
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd     
           http://www.springframework.org/schema/context     
           http://www.springframework.org/schema/context/spring-context-3.0.xsd    
           http://www.springframework.org/schema/mvc     
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 
    
    <context:component-scan base-package="com.tgb.web.controller" />     
    <bean name="/test1/multi" class="com.tgb.web.controller.MultiController">
    	<property name="methodNameResolver">
    		<ref bean="paramMethodResolver"/>
    	</property>
    </bean>
    
    <bean id="paramMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
    	<property name="paramName" value="action"></property>
    </bean>
    	
    <!-- ViewResolver 视图解析器 --> 
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/> 
        <property name="suffix" value=".jsp"/> 
    </bean>
     
</beans>

5. 写多个方法的controller

package com.tgb.web.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 MultiController extends MultiActionController{
	public ModelAndView add(HttpServletRequest request, HttpServletResponse response){
		System.out.println("-add-");
		return new ModelAndView("/multi","method","add");
	}
	public ModelAndView update(HttpServletRequest request, HttpServletResponse response){
		System.out.println("-update-");
		return new ModelAndView("/multi","method","update");
	}
}

6. 写jsp文件, 在WEB-INF下

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">    
    <title>My JSP 'welcome.jsp' starting page</title>
  </head>
  
  <body>
   	<h> 多方法controller</h> <br>
      	本次方法是${method }
  </body>
</html>

7. IE端查看

http://localhost:8080/springMVC2/test1/multi?action=update

　结果显示

多方法controller 
本次方法是update
