JSF 2.1 Spring 会话范围

Question

我的 JSF Spring 应用程序中有以下配置：

<bean id="userSessionBean" class="com.vanilla.beans.UserSessionBean" scope="session">
  <aop:scoped-proxy/>
 </bean> 

那我有Spring bean

@Service("userService")
public class UserServiceImpl implements UserService,Serializable{

@Autowired
    private UserSessionBean userSessionBean;

public String getCurrentUser(){
  return this.userSessionBean.getUserName;
}
}

现在我有了我的托管 bean：

@ManagedBean(name="userBean") @RequestScoped 公共类 UserBean {

@ManagedProperty(value="#{userService}")
    UserService userService;

   public Sttring getUserName(){
    return userService.getCurrentUser();
   }
}

然后我有 xhtml

<h:outputText value="#{userBeanBean.userName}" />

我的所有流程都可以正常工作，但是当我的会话到期时，我收到以下错误并且我单击刷新时，我有以下堆栈跟踪：

我可以解决它吗？

Answer 1

请添加：

  <listener>
    <listener-class>
      org.springframework.web.context.request.RequestContextListener
    </listener-class>
  </listener>

到你的 web.xml

如果这没有帮助，请添加有关您的 web.xml 和 jsf 配置的更多信息。
