我遇到了一个钩子的小问题。塞纳里奥:
/document_library/edit_file_entry
每当用户将文档上传到文档库时,Hook 应该覆盖调用的 struts 操作。- 目标是检查
title
文档的名称并按照给定的命名方案重命名。
我的解决方案:
@Override
public void processAction(
StrutsPortletAction originalStrutsPortletAction,
PortletConfig portletConfig, ActionRequest actionRequest,
ActionResponse actionResponse)
throws Exception {
//Get old title - set new title
String oldTitle = ParamUtil.getString(actionRequest, "title");
String newTitle = "Test";
//wrap request to set param
DynamicActionRequest actionRequestNew = new DynamicActionRequest(actionRequest);
actionRequestNew.setParameter("title", newTitle );
//call original struts action with modified title
originalStrutsPortletAction.processAction(originalStrutsPortletAction, portletConfig, actionRequestNew, actionResponse);
}
问题是使用中的原始 Strutsportal-impl/src/com/liferay/portlet/documentlibrary/action/EditFileEntryAction.java
操作 PortalUtil.getUploadPortletRequest(actionRequest);
需要PortletRequestImpl
.
但DynamicActionRequest
不能强制转换为PortletRequestImpl
.
看:

如何在不使用 DynmicActionRequest 的情况下更改参数?有什么建议么?
我正在运行 Liferay-Portal 6.1.20 EE。
