问题描述
我想知道
PortalUtil.getOriginalServletRequest(portletRequest)
和
PortalUtil.getHttpServletRequest(portletRequest).
推荐答案
查看Liferay 6的源代码(假设您正在谈论6)，您可以看到PortalUtil.getOriginalServletRequest所做的工作并将其放置在下面的代码:
Looking at the source code for Liferay 6 (I'm assuming your're talking about 6) you can see what PortalUtil.getOriginalServletRequest does and I've placed the code below:
public HttpServletRequest getOriginalServletRequest(
HttpServletRequest request) {
HttpServletRequest originalRequest = request;
while (originalRequest.getClass().getName().startsWith(
"com.liferay.")) {
// Get original request so that portlets inside portlets render
// properly
originalRequest = (HttpServletRequest)
((HttpServletRequestWrapper)originalRequest).getRequest();
}
return originalRequest;
}
因此，正如评论所述，获取原始请求，以便正确呈现portlet中的portlet".对于嵌套的portlet情况或类似情况，您可能只需要这样做.大多数时候，您只需要使用:
So as the comment says, "Get original request so that the portlets inside portlets render properly". You'll probably only require this for a nested portlet situation or similar. Most of the time you will just need to use:
PortalUtil.getHttpServletRequest(portletRequest);
我希望这会有所帮助！
