如何獲取會話中的所有已初始化的託管bean？

Question

如何在會話中獲取所有初始化的託管bean？ 以下代碼每次都會使JVM崩潰。

FacesContext facesContext=FacesContext.getCurrentInstance(); 
com.sun.faces.application.ApplicationAssociate application = 
ApplicationAssociate.getInstance(facesContext.getExternalContext()); 

Answer 1

你不能使用類似

FacesContext context = FacesContext.getCurrentInstance(); 
HttpSession session = (HttpSession) context.getExternalContext().getSession(true); 
Enumeration mySessionBeans = session.getAttributeNames();
