Additional research on liferay portal (4): Modify the default layout and content after User Logon

After the first login, liferay generates a default private homepage layout for the user. In earlier versions of liferay, you can configure the default group layout on the system administrator management interface. However, this function is not available in version 4.1, so by default, newly registered users first see the same private place content after login, these contents are provided by liferay.

This is definitely not suitable for our custom company. We need to define the content and layout displayed by default after user logon.

Later in liferay forum, I found a post to give a solution to this problem: configure a default in the portlet-ext.properties. user. layout. the Group attribute (custom) is used to specify the default Layout-group. Modify the adddefalalayouts operation in the servicepreaction class to meet specific requirements. The extension method is to copy the specified layout-group to the user's first default, so that the liferay default is no longer used. -- Of course, this method is relatively simple, and there may be more complicated requirements in the system implementation process.

 

Create a default communityFirst, add a new Community named user_default and add a private page and content. Configure the default communityFirst in the ext-EJB directory of the ext project, modify the portal-ext.properties file and add the following settings:

Default. User. layout. Group = user_default

Then, move the portal-ext.properties to the EXT/servers/tomcat/webapps/root/WEB-INF/classes directory of the ext project through build. Construct the layoutcopy classPublic class layoutcopy ...{

Private Static log _ log = logfactory. getlog (layoutcopy. Class );

Private user;

Private string ownerid;

Private Group usergroup;
Public layoutcopy (User user )...{
Super ();

This. User = user;

This. ownerid = getownerid (user. getgroup (). getgroupid (), false );
This. usergroup = user. getgroup ();
}
