无法访问非托管Bean类内的托管属性吗?

问题描述：

是否无法通过使用@ManagedProperty(value="#{beanName}")访问非托管Bean类内的托管属性?

Is it not possible to access a managed property inside a non managed bean class by using @ManagedProperty(value="#{beanName}")?

在尝试执行此操作时，我得到一个NullPointerException！

I am getting a NullPointerException while trying to do that!

答

如果在访问其属性

If you are sure that bean is alive when you are accessing its property you can fetch it from FacesContext and access its property, but you can't inject a managed bean as property in a normal Java class.
