request:
------------------------------------------------------------------------
FacesContext context = FacesContext.getCurrentInstance();
ExternalContext ec = context.getExternalContext();
HttpServletRequest request = (HttpServletRequest) ec.getRequest();
session:
------------------------------------------------------------------------
FacesContext context = FacesContext.getCurrentInstance();
ExternalContext ec = context.getExternalContext();
HttpSession session = (HttpSession) ec.getSession(true);
------------------------------------------------------------------------
獲得session后，便可以利用session來(lái)獲得一些其它有用的東東了。比如：
session.getServletContext().getRealPath("/"); // 磁盤(pán)路徑
