从liferay门户获取HttpServletResponse

Question

我试图从liferay门户获取HttpServletResponse.我也在使用icefaces.

PortletResponse response1 = (PortletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
        HttpServletResponse response = (HttpServletResponse)response1;

我得到以下例外:

Caused by: java.lang.ClassCastException: com.liferay.portlet.RenderResponseImpl cannot be cast to javax.servlet.http.HttpServletResponse

Answer 1

尝试 PortalUtil.getHttpServletResponse(portletResponse)
