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
