springMVC多个controller总是报出404错误，什么原因？

JAVA程序：

package com.dhc.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("/welcome","method","add");

}
public ModelAndView update(HttpServletRequest request,HttpServletResponse response){
System.out.println("----update----");
return new ModelAndView("/welcome","method","update");

}

}
