在Spring Beans中使用会话范围

我使用JSF 2作为视图，使用Spring作为业务逻辑。 我正在尝试使用注释（@Scope（“session”））将会话范围设置为我的一个spring bean，但是我得到了这个exception：

SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handleFiles': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private creazione.util.FTPOperations creazione.components.HandleOldFiles.operations; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ftpOperations': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: 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? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request. 

我知道RequestContextListener。 它在我的web.xml中。 我还添加了RequestContextFilter：

   org.springframework.web.context.ContextLoaderListener     org.springframework.web.context.request.RequestContextListener    requestContextFilter org.springframework.web.filter.RequestContextFilter   requestContextFilter /* REQUEST INCLUDE FORWARD  

似乎没什么用。 我究竟做错了什么？ 谢谢！

尝试定义必须作为会话注入的bean与aop：scoped-proxy。

如果相关命名空间不存在，则还要添加它：

 
		      	
 如果您使用基于注释的配置，只需在主配置xml中更改此标记：

 此外，可以通过注释标记用于处理代理的类： 
 @Component @Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS) 
 这对我有用。 更多细节： 4.12类路径扫描，托管组件和使用Java编写配置 
 另外，如果你是通过上下文xml配置创建bean，这是另一个例子：
