我的问题是PortletRequest从HttpServletRequest
I put this sentence:
我把这句话：
PortletRequest request = (PortletRequest) HttpServletRequest.getAttribute();
What should I put into the .getAttribute();
我应该放入什么 .getAttribute();
When I developed in IBM Portlet Factory, I used .getAttribute(Constants.PORTLET_REQUEST)The Constants are into one .jar
当我在 IBM Portlet Factory 中开发时，我使用了.getAttribute(Constants.PORTLET_REQUEST)The Constants are into one.jar

You can use something like this:
你可以使用这样的东西：
(PortletRequest) request.getAttribute("javax.portlet.request");
(PortletResponse) request.getAttribute("javax.portlet.response");
Request and response are of HTTPServletRequestand HTTPSevletResponse.
请求和响应属于HTTPServletRequest和HTTPSevletResponse。

I assume you're programming a servlet since you have a HttpServletRequest and no PortletRequest. Which means you won't have a PortletRequest. You'll need to be programming portlets to get PortletRequests and in that case, the API interfaces and portlet container provide the PortletRequest.
我假设您正在编写一个 servlet，因为您有一个 HttpServletRequest 而没有 PortletRequest。这意味着您将没有 PortletRequest。您需要对 Portlet 进行编程以获取 PortletRequest，在这种情况下，API 接口和 Portlet 容器将提供 PortletRequest。
I don't know how the internals of Portlet Factory worked that you would need to obtain a PortletRequest like that but that's not typical portlet programming.
我不知道 Portlet Factory 的内部结构是如何工作的，您需要获得这样的 PortletRequest，但这不是典型的 Portlet 编程。

You say you are making a JSR 168 portlet.
你说你正在制作一个 JSR 168 portlet。
In that case your portlet class should be implementing javax.portlet.Portlet
在这种情况下，您的 portlet 类应该实现 javax.portlet.Portlet
To implement that interface you implement:
要实现该接口，请执行以下操作：
render(RenderRequest, RenderResponse)
render(RenderRequest, RenderResponse)
and
和
processAction(ActionRequest, ActionResponse)
processAction(ActionRequest, ActionResponse)
These are called by the portlet container when it decides to render your portlet or handle a user action from your portlet.
当 portlet 容器决定呈现您的 portlet 或处理来自您的 portlet 的用户操作时，它们会被调用。
The request objects RenderRequestand ActionRequestare PortletRequests. So you get it directly as an argument, you don't have to query something for it.
请求对象RenderRequest和ActionRequest是PortletRequests。因此，您可以直接将其作为参数获取，而不必为它查询某些内容。
