java - 获取不满意的依赖异常 : while using JSF @Push-annotation with Spring frame work

Question

尝试从 Primefaces PUSH 迁移到 JSF Push(Websocket)， 在 Java 项目中尝试 JSF Push 时，JSF Push 工作正常。

但是在 Spring 应用程序中尝试时，我得到以下异常

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'pushBean': Unsatisfied dependency expressed through field 'clock'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.faces.push.PushContext' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@javax.inject.Inject(), @javax.faces.push.Push(channel=clock)}

项目结构如下所示。

    public void clockAction()
    {
        Calendar now = Calendar.getInstance();
        String time = now.get(Calendar.HOUR_OF_DAY) + ":" + now.get(Calendar.MINUTE) + ":" + now.get(Calendar.SECOND);
        clock.send(time);
    }
}

请建议我是否缺少任何配置以解决此问题并使 JSF 推送正常工作？
