上面的例子都是实现
Controller,
实现
handleRequest
方法，我们想像
struts2
那样一个
action
里有多个方法怎么办？
可以继承
MultiActionController
类，在类里写多个方法。
spring-servlet.xml
里需要配置
ParameterMethodNameResolver
。
MultiController：
package com.xdy.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) throws Exception {
System.out.println("---add---");
return new ModelAndView("/welcome","method","add");
}
public ModelAndView update(HttpServletRequest request,
HttpServletResponse response) throws Exception {
System.out.println("---update---");
return new ModelAndView("/welcome","method","update");
}
}
spring-servlet.xml
：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
