用的是MultiActionController，訪問http://localhost:8080/WBReport/welcomeController.do?action=showList地址報錯
錯誤如下：
[2010-09-28 23:50:12] - org.springframework.web.servlet.PageNotFound -2714414 [h
ttp-8080-5] WARN  org.springframework.web.servlet.PageNotFound  - No request han
dling method with name 'showList' in class [com.wolfbase.test.WelcomeController]
以前寫的代碼可以運行，從網上copy如下的例子也不能運行，暈死；后來終于找到問題的原因：
ModelAndView ：org.springframework.web.portlet.ModelAndView;
應該是來自:org.springframework.web.servlet.ModelAndView; 費了1個多小時呀！


package com.wolfbase.test;

import java.util.HashMap;
import java.util.Map;

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

import org.springframework.web.portlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class WelcomeController extends MultiActionController {  
 
    private String successView;  
    public void show(HttpServletRequest req,  
       HttpServletResponse resp) { 
     System.out.println("show-WelcomeController");
    }
    public ModelAndView showList(HttpServletRequest req,  
            HttpServletResponse resp) {  
        Map model = new HashMap();  
        model.put("success", "成功");  
        return new ModelAndView(this.getSuccessView(), model);  
    }  
  
     public ModelAndView addUser(HttpServletRequest req,  
             HttpServletResponse resp) {  
         Map model = new HashMap();  
         model.put("success", "增加用戶成功");  
         return new ModelAndView(this.getSuccessView(), model);  
     }  
  
     public String getSuccessView() {  
         return successView;  
     }  
  
     public void setSuccessView(String successView) {  
         this.successView = successView;  
     }
