liferay中站点的建立及封装一个Util类用于站点模板的引用

写这篇文章主要是记录一下在项目开发中遇到问题,分析问题,解决问题的过程.

由于项目需求,需要把创建站点,站点模板引用单独从控制面板中拿出来,于是去开始着手源码的阅读,这篇文章重点不在这,所以略去.

首先说一下组织和站点的关系

1.Organization和Group  
每创建一个Organization 就会有一个对应的Group    
表group\_的classPK存的就是organizationId  
2.Organization和Site  
在liferay中建立了组织后可以为该组织创建站点  
组织存在表organization\_中,而站点是存在表layoutset中

下面是创建站点并引用站点模板的一个大体步骤:

1.利用OrganizationLocalServiceUtil的addOrganization方法创建一个常规组织,默认建立了一个站点,该方法返回一个Organization对象

Organization organization = OrganizationLocalServiceUtil.addOrganization(userId, parentOrganizationId, name, type, recursable, regionId, countryId, statusId, comments, site, serviceContext);

各项参数说明可以查看api(6.1.1CE),地址: [http://docs.liferay.com/portal/6.1/javadocs/com/liferay/portal/service/OrganizationLocalServiceUtil.html][http_docs.liferay.com_portal_6.1_javadocs_com_liferay_portal_service_OrganizationLocalServiceUtil.html]

2.建立常规组织以后,默认建立以一个group,接着,为新建立的站点添加模板,这里如果调用LayoutSetUtil类的方法添加的话,新站点可能引用不到,于是需要自己封装一个Util类,出处:[http://pastebin.com/hPNrG212][http_pastebin.com_hPNrG212],代码如下:

package com.example.util;
    
    import com.liferay.portal.kernel.exception.PortalException;
    import com.liferay.portal.kernel.exception.SystemException;
    import com.liferay.portal.kernel.util.MethodKey;
    import com.liferay.portal.kernel.util.PortalClassInvoker;
    import com.liferay.portal.model.Group;
    import com.liferay.portal.model.LayoutSet;
    import com.liferay.portal.model.LayoutSetPrototype;
    import com.liferay.portal.service.GroupLocalServiceUtil;
    import com.liferay.portal.service.LayoutSetLocalServiceUtil;
    import com.liferay.portal.service.LayoutSetPrototypeLocalServiceUtil;
    
    public class LayoutsetUtil {
    	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) {
    			e.printStackTrace();
    		}
    	}
    
    	public static void mergeLayoutSetProtypeLayouts(Group group,
    			LayoutSet layoutSet) throws Exception {
    
    		MethodKey key = SitesUtilMethodKey("mergeLayoutSetProtypeLayouts",
    				Group.class, LayoutSet.class);
    		invokePortalClassMethod(key, group, layoutSet);
    	}
    
    	/*

    	 * 
    	 * key: key of method to be called, e.g.
    	 * com.liferay.portlet.sites.util.SitesUtil arguments: arguments to be
    	 * passed to the invoked method returns: result of the invoked method
    	 */
    	private static Object invokePortalClassMethod(MethodKey key,
    			Object... arguments) throws PortalException {
    		try {
    			// noinspection unchecked
    			return PortalClassInvoker.invoke(false, key, arguments);
    		} catch (PortalException e) {
    			throw e;
    		} catch (Exception e) {
    			throw new RuntimeException(e);
    		}
    	}
    
    	private static final String SITES_UTIL_CLASS_NAME = "com.liferay.portlet.sites.util.SitesUtil";
    
    	private static MethodKey SitesUtilMethodKey(String methodName,
    			Class<?>... parameterTypes) {
    		return new MethodKey(SITES_UTIL_CLASS_NAME, methodName, parameterTypes);
    	}
    }

调用LayoutsetUtil的setupSitesFromSiteTemplate(long groupId,long publicSiteTemplateId, long privateSiteTemplateId)传入相应的参数就可以引用到站点模板了,下面对三个参数做一点说明

1.groupId:新建站点的groupId,可以通过organization.getGroupId()获取

2. publicSiteTemplateId(在公开页面引用):站点模板的id,可以在表layoutsetorototype表中查看layoutsetorototypeid获取,也可以通过api获取

3.privateSiteTemplateId(在私有页面引用):获取方式同 publicSiteTemplateId

当然了,我们还可能为站点设置了自定义字段,我们也可以用api来实现,代码如下:

// 给站点添加自定义字段
    siteGroupId = organization.getGroupId();
    Group group = GroupLocalServiceUtil.getGroup(organization.getGroupId());
    group.getExpandoBridge().setAttribute("appCode", "cg");

于是,我们在控制面板中看到这样的效果:
