如何从代码中以编程方式删除Liferay 6.1中的Portlet [英] How to delete a portlet in Liferay 6.1 programmatically from code

问题描述

我正在使用Liferay 6.1
我想从代码中删除Liferay 6.1中的portlet. 到目前为止，我所做的是:

I'm working on Liferay 6.1
I want to delete a portlet in Liferay 6.1 from my code. What I have done so far is:

<a onclick="Liferay.Portlet.close('#p_p_id_28_'); return false;">Remove</a>

以上代码运行正常.但是它仅在当前页面上起作用，即它可以删除仅在当前页面上存在的portlet.

Above code is working fine. But it is working on the current page only i.e. it can delete the portlet(s) which is there on the current page only.

但是我想使用其布局ID删除可能在门户菜单上某些位置的portlet.

But I want to delete the portlet(s) which could be some where on the menu of my portal using its layout id.

请提出一条出路. 预先感谢.

Please suggest a way out. Thanks in advance.

public void removePortlets(ActionRequest request, ActionResponse response)
            throws PortletException {
        ThemeDisplay themeDisplay = (ThemeDisplay) request
                .getAttribute(WebKeys.THEME_DISPLAY);
        long groupId = themeDisplay.getScopeGroupId();
        String friendlyURL = "/demochildpage";
        boolean privateLayout = false;
        long userId = themeDisplay.getUserId();
        try {
            Layout layout = LayoutLocalServiceUtil.getFriendlyURLLayout(
                    groupId, privateLayout, friendlyURL);
            LayoutTypePortlet layoutTypePortlet = (LayoutTypePortlet) layout
                    .getLayoutType();
            layoutTypePortlet.removePortletId(userId, "28");
            LayoutLocalServiceUtil.updateLayout(layout.getGroupId(),
                    layout.getPrivateLayout(), layout.getLayoutId(),
                    layout.getTypeSettings());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
