Spring MVC:noHandlerFound

我正在用Mybatis+Spring3+Tomcat+EclipseIndigo做SpringMVC示例，我遇到了这个问题 发生了什么？任何成功运行此项目的建议。以前的问题已清除，请运行此错误消息

  org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/SpringMVC/] in DispatcherServlet with name 'spring'

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="mapperLocations" value="classpath:logen/board/dao/BoardDao.xml" />
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg index="0" ref="sqlSessionFactory" />
</bean> 

<bean id="BoardDao" class="logen.board.entity.BoardEntity"></bean>

这里是我的web.xml

 <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

你要什么网址？你的应用程序上下文是什么？我想。。应用程序就是应用程序上下文，不是吗？其他要求吗？您只有APPCONTEXT/list.do的映射。谢谢各位，祝您度过愉快的一天

@Controller
public class Boardcontroller {
    @Autowired
    private SqlSession sql;
    @Autowired
    private BoardEntity bn;
    @RequestMapping("/list.do")
    private ModelAndView list(){
        BoardDao dao = sql.getMapper(BoardDao.class);
        ModelAndView mv = new ModelAndView();
        mv.setViewName("jsp/index");
        mv.addObject("list", dao.getList());
        return mv;
    }
}
