public class FacesUtil {
    public static HttpServletResponse getResponse(){
        /**
         * JSF获取response
         * @return
         */
        FacesContext facesContext = FacesContext.getCurrentInstance();
        facesContext.responseComplete();
        HttpServletResponse response = (HttpServletResponse) facesContext.getExternalContext().getResponse();
        facesContext.responseComplete();
        return response;
    }

    public static HttpServletRequest getRequest(){
        /**
         * JSF获取request
         * @return
         */
        FacesContext facesContext = FacesContext.getCurrentInstance();
        facesContext.responseComplete();
        HttpServletRequest request = (HttpServletRequest) facesContext.getExternalContext().getRequest();
        facesContext.responseComplete();
