? Liferay
在用戶第一次登陸后，都會為其產生一個默認的私有首頁
Layout。?在
Liferay早期版本，可以在系統管理員管理界面中，配置默認的group layout。但是在4.1版本中已經沒有這個功能，所以默認情況下，新注冊的用戶，在登陸后，首先看到的其私有place都是一樣的內容，而這些內容都是liferay提供的。

對我們自定的
Company來說，這肯定是不合適的，我們需要自己定義用戶登錄后，默認顯示的內容和布局。
?
???
后來在Liferay forum中，找到了一篇帖子，給了解決此種問題的解決辦法：在portlet-ext.properties中配置一個 default.user.layout.group 屬性（自定義的），用于指明默認的layout-group。在
ServicePreAction
類的擴展修改 addDefaultLayouts 操作，滿足特定的需求應用。這種擴展的方式就是，將指定layout-group拷貝給用戶第一默認的，這樣就不會再使用liferay默認的了。—— 當然這樣的方式是比較簡單的，可能在系統實施過程中，有比這更加復雜的需求。
?
新建默認的
Community
首先，通過新增一個新的
Community，命名為User_Default，并新增一個private的page與內容.
?
配置默認的
Community
首先在
ext項目的 ext-ejb目錄下，修改portal-ext.properties文件，增加如下設置：
|
?
default.user.layout.group
=User_Default
|
然后通過
build，將portal-ext.properties移動到 ext項目的
??? ext\servers\tomcat\webapps\ROOT\WEB-INF\classes
目錄下。
