看异常，用配置没问题。但是注解会报错，求解答！！！

public class ApplicationListener implements ServletContextListener {

    @Override

        //获取日志操作的对应数据
        Map<String, String> noteOperMap = noteOperDAO.queryAllForMap();
        //将查询到的结果存放至作用域
        servletContext.setAttribute("noteTableMap", noteTableMap);
        servletContext.setAttribute("noteOperMap", noteOperMap);
    }
}

自己解决的：理由是，filter listener servlet 无法由spring 管理，因此用注解获取不到相应对象，必须通过getBean 的方式来获取。
值得一提的是，通过注解过的类也可以通过getBean("")方式获取到，而不必再进行相关配置。
解决方案：

 public class ApplicationListener implements ServletContextListener {
    //获取spring注入的bean对象
    private WebApplicationContext springContext;
    private NoteTableDAO noteTableDAO;
    private NoteOperDAO noteOperDAO;

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        // TODO Auto-generated method stub
        this.springContext = null;
        this.noteTableDAO = null;
        this.noteOperDAO = null;
    }

    @Override
    public void contextInitialized(ServletContextEvent servletcontextevent) {
        // TODO Auto-generated method stub
        //获取ServletContext对象
        ServletContext servletContext = servletcontextevent.getServletContext();
        //服务器启动的时候加载日志需要的信息
        noteMap(servletContext);
    }

    private void noteMap(ServletContext servletContext) {
        // TODO Auto-generated method stub
        springContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);
        if (springContext != null) {
            noteOperDAO = (NoteOperDAO) springContext.getBean("noteOperDAO");
            noteTableDAO = (NoteTableDAO) springContext.getBean("noteTableDAO");
            //获取日志表的对应数据
            Map<String, String> noteTableMap = noteTableDAO.queryAllForMap();
            //获取日志操作的对应数据
            Map<String, String> noteOperMap = noteOperDAO.queryAllForMap();
            //将查询到的结果存放至作用域
            servletContext.setAttribute("noteTableMap", noteTableMap);
            servletContext.setAttribute("noteOperMap", noteOperMap);
        }
    }

    public NoteTableDAO getNoteTableDAO() {
        return noteTableDAO;
    }

    public void setNoteTableDAO(NoteTableDAO noteTableDAO) {
        this.noteTableDAO = noteTableDAO;
    }

    public NoteOperDAO getNoteOperDAO() {
        return noteOperDAO;
    }

    public void setNoteOperDAO(NoteOperDAO noteOperDAO) {
        this.noteOperDAO = noteOperDAO;
    }

@Resource 是byName jdk自带的注入 如果有多个或者没有名字，会抛出异常。 @Autowired是byType 可以用@Autowired试试 Spring的注入

Autowired能完成的 Resource都能完成。况且Listener是属于JavaEE范畴，怎么可能用Autowired？所以这个结论肯定是不成立的。

    你这里是找到多个name重名的，
