Question

我的网站目前基于网站模板。我想删除此站点中的所有页面（保留内容），并将站点链接到新的站点模板。

Jira issue LPS-33179从GUI的角度提出了问题。我想从编码员的角度来了解。

我正在使用Liferay 6.1.0 GA2。

谢谢，阿兰

这是我使用的，似乎有效：

LayoutSetLocalServiceUtil.updateLayoutSetPrototypeLinkEnabled

设置原型的链接，

SitesUtil.mergeLayoutSetProtypeLayouts

立即更新网站。使用基于code from Jelmer Kuperus

的PortalClassInvoker调用后者

public static void setupSitesFromSiteTemplate(long groupId, long publicSiteTemplateId,
                                              long privateSiteTemplateId) throws PortalException, SystemException {
    Group group = GroupLocalServiceUtil.getGroup(groupId);
    if (publicSiteTemplateId != 0) setSiteTemplate(group, publicSiteTemplateId, false);
    if (privateSiteTemplateId != 0) setSiteTemplate(group, privateSiteTemplateId, true);
}

public static void setSiteTemplate(Group group, long siteTemplateId, boolean isPrivateLayout)
        throws PortalException, SystemException {
    long groupId = group.getGroupId();
    LayoutSetPrototype prototype = LayoutSetPrototypeLocalServiceUtil.getLayoutSetPrototype(siteTemplateId);
    boolean layoutSetPrototypeLinkEnabled = true;
    LayoutSetLocalServiceUtil.updateLayoutSetPrototypeLinkEnabled(groupId, isPrivateLayout,
            layoutSetPrototypeLinkEnabled, prototype.getUuid());
    try {
        LayoutSet layoutSet = LayoutSetLocalServiceUtil.getLayoutSet(groupId, isPrivateLayout);
        mergeLayoutSetProtypeLayouts(group, layoutSet);
    } catch (Exception e) {
        if (_log.isWarnEnabled()) {
            String privatePublic = isPrivateLayout ? "private" : "public";
            _log.warn(String.format("Could not merge %s layouts for group[%d] from template[%d]", privatePublic,
                    groupId, siteTemplateId));
            e.printStackTrace();
        }
    }
}

public static void mergeLayoutSetProtypeLayouts(Group group, LayoutSet layoutSet) throws Exception {

    MethodKey key = SitesUtilMethodKey("mergeLayoutSetProtypeLayouts", Group.class, LayoutSet.class);
    invokePortalClassMethod(key, group, layoutSet);
}
