我学习了如何从 jsp 访问会话范围的 sping bean，但出现以下错误：

No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? scoped beans from jsp

request.getSession().getAttribute("scopedTarget.otmSessionHolder")).getUserVO()

我的 web.xml：

 <listener>
            <description>Spring Context Listener</description>
            <display-name>Spring Context Listener</display-name>
            <listener-class>
                org.springframework.web.context.ContextLoaderListener
            </listener-class>
        </listener>

        <listener>
            <display-name>Request Context Listener</display-name>
            <listener-class>
                org.springframework.web.context.request.RequestContextListener
            </listener-class>
        </listener>

            </init-param>

    </servlet>

<servlet>

        </init-param>

        <load-on-startup>1</load-on-startup>
    </servlet>

但是我仍然得到这个例外我使用sitemesh装饰器作为模板。一直在通过这些论坛，但无济于事。请帮助我
