我正在尝试配置 session 注册 portlet 的权限。我已将 portlet.properties 文件添加到 portlet 的 docroot/WEB-INF/src 目录中。添加以下行会导致异常:
resource.actions.configs=resource-actions/default.xml
default.xml 如下所示:
<?xml version="1.0"?>
<!DOCTYPE resource-action-mapping PUBLIC "-//Liferay//DTD Resource Action Mapping 6.1.0//EN" "http://www.liferay.com/dtd/liferay-resource-action-mapping_6_1_0.dtd">
<resource-action-mapping>
<resource file="resource-actions/meetingsignup.xml" />
</resource-action-mapping>
meetingsingup.xml 如下所示:
<?xml version="1.0"?>
<resource-action-mapping>
<portlet-resource>
<portlet-name>meeting_signup</portlet-name>
<permissions>
<supports>
<action-key>CREATE_MEETING</action-key>

即当我部署 portlet 时，日志写道:

为什么会发生这种异常，如何消除它？我已经在网上搜索过答案，但找不到。
最佳答案
- 尝试删除第一个斜杠:
resource.actions.configs=resource-actions/default.xml - 仔细检查default.xml是否存在，并且它位于名为resource-actions的文件夹中，并且该文件夹与一起位于WEB-INF/src文件夹下>portlet.properties
- 打开default.xml并确保其内部结构符合Liferay Resource Mapping DTD (上一个链接适用于 Liferay 6.1)
关于permissions - 当我将 portlet.properties 文件添加到 portlet 时，为什么会收到 HotDeployException？ (Liferay 门户开发)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13368482/
