In my case, I am using Liferay Portal, so in order to avoid this error
I changed:
就我而言，我使用的是 Liferay Portal，因此为了避免此错误，我更改了：
<%@ taglib uri="http://java.sun.com/portlet_2_0"% prefix="portlet">
to
到
<%@ taglib uri="/WEB-INF/tld/liferay-portlet.tld" prefix="portlet" %>
and in file "WEB-INF/liferay-plugin-package.properties"; I added this line
并在文件“WEB-INF/liferay-plugin-package.properties”中；我添加了这一行
portal-dependency-tlds=/WEB-INF/tld/liferay-portlet.tld
which is suggested by a Liferay staff (Link)
这是 Liferay 工作人员建议的（链接）

Remove the line
删除该行
<%@ taglib uri="http://java.sun.com/portlet_2_0"% prefix="portlet">
and paste this line:
并粘贴这一行：
<%@taglib uri="http://java.sun.com/portlet" prefix="portlet"%>
Then, in WEB-INF/tldfolder put these files: aui.tld, liferay-portlet.tld, liferay-portlet-ext.tld, liferay-security.tld, liferay-theme.tld, liferay-ui.tld, liferay-util.tld.
然后，在WEB-INF/tld文件夹中放入这些文件：aui.tld, liferay-portlet.tld, liferay-portlet-ext.tld, liferay-security.tld, liferay-theme.tld, liferay-ui.tld, liferay-util.tld.

If you add this to the web.xml in the WEB-INF folder it will remove the Eclipse error message.
如果您将此添加到 WEB-INF 文件夹中的 web.xml，它将删除 Eclipse 错误消息。
<web-app>
<taglib>
<taglib-uri>http://java.sun.com/portlet_2_0</taglib-uri>
<taglib-location>/WEB-INF/tld/liferay-portlet.tld</taglib-location>
</taglib>
</web-app>
Hope it helps.
希望能帮助到你。

This error just means that Eclipse is unable to find a tag library descriptor (TLD) that resolves the given (http://java.sun.com/portlet_2_0) tag URI. You can download the TLD corresponding to your portal container (Gatein, Pluto, Liferay, etc) from GitHub and place it in WEB-INF folder. Gatein specific tld can be found here. Also, make sure that you have the portlet_2.0 jar in your project path.
此错误仅表示 Eclipse 无法找到解析给定 ( http://java.sun.com/portlet_2_0) 标记 URI的标记库描述符 (TLD) 。您可以从 GitHub 下载与您的门户容器（Gatein、Pluto、Liferay 等）对应的 TLD，并将其放在 WEB-INF 文件夹中。Gatein 特定的 tld 可以在这里找到。此外，请确保您的项目路径中有 portlet_2.0 jar。

You can download portlet-2.0.jarand add it to your project path. But if you are developping for Liferay I would recommand you to use the liferay-portlet.tldwhich has the portlet 2.0 specification.
您可以下载portlet-2.0.jar并将其添加到您的项目路径中。但是，如果您正在为 Liferay 进行开发，我建议您使用liferay-portlet.tld具有 portlet 2.0 规范的 。
