 [Java Open Source]Liferay Portal额外研究（4）：修改用户登录后的默认布局和内容
软件技术
lhwork 发表于 2006/9/4 18:07:06 |
| Liferay在用户第一次登陆后，都会为其产生一个默认的私有首页Layout。 在Liferay早期版本，可以在系统管理员管理界面中，配置默认的group layout。但是在4.1版本中已经没有这个功能，所以默认情况下，新注册的用户，在登陆后，首先看到的其私有place都是一样的内容，而这些内容都是liferay提供的。 对我们自定的Company来说，这肯定是不合适的，我们需要自己定义用户登录后，默认显示的内容和布局。 后来在Liferay forum中，找到了一篇帖子，给了解决此种问题的解决办法：在portlet-ext.properties中配置一个 default.user.layout.group 属性（自定义的），用于指明默认的layout-group。在ServicePreAction类
的扩展修改 addDefaultLayouts
操作，满足特定的需求应用。这种扩展的方式就是，将指定layout-group拷贝给用户第一默认的，这样就不会再使用liferay默认的了。——
当然这样的方式是比较简单的，可能在系统实施过程中，有比这更加复杂的需求。 新建默认的Community首先，通过新增一个新的Community，命名为User_Default，并新增一个private的page与内容. 配置默认的Community首先在ext项目的 ext-ejb目录下，修改portal-ext.properties文件，增加如下设置： default.user.layout.group=User_Default 然后通过build，将portal-ext.properties移动到 ext项目的 ext\servers\tomcat\webapps\ROOT\WEB-INF\classes 目录下。 构造LayoutCopy类500)this.width=500'>500)this.width=500'>public class LayoutCopy ...{500)this.width=500'> 500)this.width=500'> private static Log _log = LogFactory.getLog(LayoutCopy.class);500)this.width=500'> 500)this.width=500'> private User user;500)this.width=500'>500)this.width=500'> private String ownerId;500)this.width=500'>500)this.width=500'> private Group userGroup;500)this.width=500'>500)this.width=500'> public LayoutCopy(User user) ...{500)this.width=500'> super();500)this.width=500'>500)this.width=500'> this.user = user;500)this.width=500'>500)this.width=500'> this.ownerId = getOwnerId(user.getGroup().getGroupId(), false);500)this.width=500'> this.userGroup = user.getGroup();500)this.width=500'> }500)this.width=500'>500)this.width=500'> public void copyDefaultUserLayout(HttpServletRequest httpReq)500)this.width=500'>500)this.width=500'> throws SystemException, PortalException ...{500)this.width=500'> // set in the portal-ext.properties:500)this.width=500'> // default.user.layout.group=Default User500)this.width=500'> // and create then group/community "Default User" 500)this.width=500'> // CWPPropsUtil.DEFUALT_USER_LAYOUT_GROUP = "default.user.layout.group"500)this.width=500'> Group group = GroupLocalServiceUtil.getGroup(user.getCompanyId(),500)this.width=500'> PropsUtil.get("default.user.layout.group"));500)this.width=500'>500)this.width=500'>500)this.width=500'> try ...{500)this.width=500'> String groupOwnerId = getOwnerId(group.getGroupId(), true);500)this.width=500'> List privateLayouts = LayoutLocalServiceUtil500)this.width=500'> .getLayouts(groupOwnerId);500)this.width=500'>500)this.width=500'>500)this.width=500'> for (Iterator itr = privateLayouts.iterator();

} (new LayoutCopy(user)).copyDefaultUserLayout(httpReq); } 然后，修改run方法中对原始addDefaultLayouts方法的调用方法： if (layoutsRequired) { String user_layout_group = PropsUtil.get("default.user.layout.group"); if(user_layout_group==null || user_layout_group.length()==0){ addDefaultLayouts(user); }else{ addDefaultLayouts(req, user); } } |
