springMVC中的控制器之一——MultiActionController

注：该控制器需使用方法解析器，PropertiesMethodNameResolver只是其中的一种，这个控制器在spring4之后就没有了。

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>01-springMVCPrimary</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- 注册中央调度器 -->
  <servlet>
  	<servlet-name>springMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<!-- 指定springMVC的配置文件的位置和路径 -->
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:springMVC.xml</param-value>
  	</init-param>
  	<!-- 表示启动服务器就创建该对象，不设置的话，那么就在请求到达时，创建该对象 -->
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
  
</web-app>

2、springMVC.xml

<?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:context="http://www.springframework.org/schema/context" 
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop.xsd">
        
		
		<!-- 注册处理器映射器 -->
		<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
			<property name="urlMap">
				<map>
					<entry key="/my_*.do" value-ref="myController"/>
				</map>
			</property>
		</bean>
		
		<!-- 注册方法解析器 -->
		<bean id="myPropertiesMethodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
			<property name="mappings">
				<props>
					<prop key="/my_first.do">doFirst</prop>
					<prop key="/my_second.do">doSecond</prop>
				</props>
			</property>
		</bean>
		        
        <!-- 注册控制器 -->
		<bean id="myController" class="com.handlers.MyController">
			<property name="methodNameResolver" ref="myPropertiesMethodNameResolver"/>
		</bean>
</beans>

3、MyController

package com.handlers;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import org.springframework.web.servlet.mvc.multiaction.NoSuchRequestHandlingMethodException;

public class MyController extends MultiActionController {

	
	public ModelAndView doFirst(HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message", "执行doFirst()方法");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
	
	
	public ModelAndView doSecond(HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message", "执行doSecond()方法");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
	
}
