I'm working with : Liferay 6.0.6 with JBoss 5.1 and Struts2.

My question is, how to get the current user in Liferay once logged in, using a Java code.

  • I meant, the solution should be a Java Code and we have to retrieve the current user by E-mail :) – Sabrina May 04 '12 at 12:16

In your doView/processAction method do following

User user = (User) request.getAttribute(WebKeys.USER);

or use the ThemeDisplay object. It contains another information like companyId, groupId, ...

ThemeDisplay td  =(ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
User user = td.getUser();

Classes ThemeDisplay, User nad WebKeys are part of portal-service.jar.

If you need just some id to identify current user you can also use 

String userId = request.getRemoteUser();

This solution is not Liferay specific and should be portable among jsr-286 portals.

    can you tell me more about the instance "request". how to initialize it ? – Sabrina May 04 '12 at 12:55

    Its either RenderRequest, ActionRequest, EventRequest or ResourceRequest. If you are not familiar with them then you should read some portlet tutorial, e.g http://www.liferay.com/documentation/liferay-portal/6.0/development/-/ai/understanding-the-two-phases-of-portlet-execution – František Hartman May 04 '12 at 19:28
  • User currentUser = LiferayFacesContext.getInstance().getUser(); – Aalkhodiry Oct 28 '13 at 15:22

Liferay provides Util class

com.liferay.portal.util.PortalUtil

This class contains all utility methods to get the frequently used attributes.

Try using PortalUtil.getUser(PortletRequest portletRequest) method to avoid creating new objects and references.

  • What's is the different with ThemeDisplay? – TuGordoBello May 26 '15 at 14:07
  • @zhelon, nothing, you fetch themeDisplay from request, and then getUser() from it, PortalUtil.getUser() fetches the same from request, if you see PortalImpl.getUser() then you will notice this request.getAttribute(WebKeys.USER); – Felix Christy May 27 '15 at 07:44

This is an other possible way to do it :

private LiferayFacesContext liferayFacesContext = LiferayFacesContext.getInstance();
User currentUser=liferayFacesContext.getUser()
