我们在liferay 中有一个叫做嵌套portlet 的东西。我想通过代码动态添加这个portlet。有谁知道添加嵌套 portlet 并在其中添加其他 portlet 的代码?
谢谢 !!!
对于完整的示例,我假设您想使用另一个 portlet 操作处理程序将嵌套的 portlet 添加到当前页面。(如果从渲染操作中使用,直到页面的下一个视图,您才会看到嵌套的 portlet)
将这些方法添加到您的代码中
private static String addPortlet(final long p_userId, final Layout p_layout, final String p_portletId, final String p_columnId, final int p_position, final boolean p_checkPermission)
throws PortalException, SystemException
{
if (p_layout.isTypePortlet()) {
final LayoutTypePortlet layoutTypePortlet = (LayoutTypePortlet) p_layout.getLayoutType();
final String portletId = layoutTypePortlet.addPortletId(p_userId, p_portletId, p_columnId, p_position, p_checkPermission);
if (portletId != null) {
final String rootPortletId = PortletConstants.getRootPortletId(portletId);
final String portletPrimaryKey = PortletPermissionUtil.getPrimaryKey(p_layout.getPlid(), portletId);
ResourceLocalServiceUtil.addResources(p_layout.getCompanyId(), p_layout.getGroupId(), 0, rootPortletId, portletPrimaryKey, true, true, true);
LayoutLocalServiceUtil.updateLayout(p_layout.getGroupId(), p_layout.isPrivateLayout(), p_layout.getLayoutId(), p_layout.getTypeSettings());
}
return portletId;
}
return null;
}
private static void addNestedPortlet(final PortletRequest p_request) throws PortalException, SystemException {
final ThemeDisplay themeDisplay = (ThemeDisplay) p_request.getAttribute(WebKeys.THEME_DISPLAY);
final Layout layout = themeDisplay.getLayout();
long userId = themeDisplay.getUserId();
//create nested portlet and add it to "column-1"
final String nestedPortletId = addPortlet(userId, layout, "118", "column-1", -1, false);
//this will be used to target nested portlet's columns
final String nestedColumnPrefix = "_" + nestedPortletId + "__";
//default page layout (used by nested portlet) has two columns
//we'll add two portlets (in this example two iframe portlets), one portlet to each column
addPortlet(userId, layout, "48", nestedColumnPrefix + "column-1", -1, false);
addPortlet(userId, layout, "48", nestedColumnPrefix + "column-2", -1, false);
}
如果您希望并且可能您希望将嵌套的 portlet 添加到另一个页面或不从 portlet 中添加,您可以查找 Layout 和 User 而不是从 ThemeDisplay 中获取它们。
