package com.video.web;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.video.model.Videotab;
import com.video.service.videoService;

@Controller
@RequestMapping(""/video/*"")
public class videoControl {
@Resource
public videoService service;

@RequestMapping( value=""select""method=RequestMethod.GET)public ModelAndView addtest(){    Videotab videotab= new Videotab();    videotab.setVedioid(88);    List<Videotab> list=service.selectVideo(videotab);    System.out.println(""id---""+list.get(0).getVedioid()+""/r""+""title----""+list.get(0).getVediotitle());    return null;}

}

解决方案

@RequestMapping(""/video/*"")改成@RequestMapping(""video"")

解决方案二：
修改下springmvc的配置路径为/*

 <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>/*</url-pattern></servlet-mapping>

解决方案三：
Tomcat启动正常吗？调试下呗。
