javax.naming.NameNotFoundException:名称[SessionFactory]在此上下文中未绑定。找不到[SessionFactory]

我正在尝试在我的Spring应用程序中使用Hibernate进行Db访问。但现在，我得到了以下错误：

Could not locate SessionFactory in JNDI

正在通过以下方式从我的控制器调用此方法：

@RequestMapping(value="/login", method=RequestMethod.POST)
    public ModelAndView login(@RequestParam("username") String username, @RequestParam("password") String password) throws NoSuchAlgorithmException
    {
        MessageDigest md = MessageDigest.getInstance("MD5");
        md.update(password.getBytes());
        byte[] digest = md.digest();

        Usuario temp = new Usuario(username, convertByteToHex(digest));
        UsuarioHome tempHome = new UsuarioHome();
        List<Usuario> lista = tempHome.findByExample(temp);
        if(lista.size() == 0) {
            ModelAndView mav = new ModelAndView();
            mav.setViewName("usuario_login");
            mav.addObject("message", "N&atilde;o foi possivel efetuar o login");
            return mav;
        }
        else {
            this.sessao = new Sessao();
            ModelAndView mav = new ModelAndView();
            mav.setViewName("usuario_start");
            mav.addObject("usuario", temp);
            return mav;
        }
    }

并将此行添加到我的类主页（DAO类）：

我不知道我所做的是否正确，但错误消息更改为：

您的错误是由

（SessionFactory）new InitialContext（）引起的。查找（“SessionFactory”）

。由于您使用的是spring框架，我建议您使用IoC方法，而不是使用InitialContext

要使用SessionFactory，您需要使用几个属性初始化该类，例如dataSource、hibernateProperties、entities等。。通常使用XML或注释驱动的方法来完成。您可以配置SessionFactory并让它存在于IoC容器中，然后将其注入到您的主类中

上面的链接显示了这两种方法（XML和注释）。尝试跟踪它并设置bean=D

更新：这个mkyong的教程包含了一步一步的教程，非常清晰

我在我的项目中做了一个更改，尝试按照您指示我的第一个链接的方向进行操作，事实上，我收到了一条新的错误消息。你能看看我的更新，看看我现在做错了什么吗？如果有任何帮助，我将不胜感激。您能给我看看您的spring-servlet.xml吗？您应该在UsuarioHome类中执行@Autowired SessionFactory SessionFactory。这是我的spring（？）-servlet.xml（您是指ligadesportiva-servlet.xml，对吗？它是web.xml文件中的servlet名称）->。我把@Autowired也放在了我的家庭课上。表示需要将context:annotation-config标记添加到*servlet.xml。试一试？它可以停止上面的NullPointerException，但现在我出现了以下错误：
