找不到 Liferay jsp 页面

Question

我在重定向到 jsp 页面时遇到问题。

    <portlet:renderURL var="DLMSnewSearch">
    <portlet:param name="mvcPath" value="/view.jsp" />
</portlet:renderURL>
<p>
    <a href="<%=DLMSnewSearch%>">&larr; New Search</a>
</p>

Eclipse 抛出警告：未找到类型“/view.jsp”。

抛出异常：

它一直有效，直到我重新安装 Linux Mint 并从现有源添加 Liferay 项目...这是我从以前的 Mint 保存的备份。提前致谢。

由于您使用Eclipse IDE 为Liferay 开发，我相信以下内容将适用。您可以通过关注此错误跟踪器获得软件补丁，或等待将其合并到滚动版本中。

JIRA issue: IDE-1855 - The jsp tag "param" has incorrect validation

日食JavaIDE

听起来您受到了 Liferay 软件中已知错误的影响。 Work-around 通过在 IDE 中执行以下步骤来实现此行为：

打开“项目属性”对话框。
Select "Validation" 页面。
勾选复选框，"Enable project specific settings."
找到 "JSP Reference Validation," 设置并将其关闭以进行手动和构建。
