WebSphere Portal获取当前登录用户名的三种方式

方法一：采用Portal的Puma API

Java代码

1. Context ctx =  new  InitialContext();   
2. PortletServiceHome pumaServiceHome = (PortletServiceHome) ctx.lookup( "portletservice/com.ibm.portal.um.portletservice.PumaHome" );                  
3. PumaHome puma_home =  null ;                 
4. if  (pumaServiceHome !=  null ){   
5.            
6.     puma_home = (PumaHome) pumaServiceHome.getPortletService(PumaHome. class );   
7. }   
8. PumaProfile pp = puma_home.getProfile();   
9. User user = pp.getCurrentUser();   
10. String uid = pp.getIdentifier(user);   

    Context ctx = new InitialContext();
PortletServiceHome pumaServiceHome = (PortletServiceHome) ctx.lookup("portletservice/com.ibm.portal.um.portletservice.PumaHome");				
PumaHome puma_home = null;				
if (pumaServiceHome != null){
		
	puma_home = (PumaHome) pumaServiceHome.getPortletService(PumaHome.class);
}
PumaProfile pp = puma_home.getProfile();
User user = pp.getCurrentUser();
String uid = pp.getIdentifier(user); 
  

方法二：采用传统的Request方式

Java代码

1. request.getUserPrincipal().getName();  或 request.getRemoteUser();

    request.getUserPrincipal().getName();
  

     request.getRemoteUser();
  

方法三：采用Taglib方式

Java代码

1. <%@ taglib uri= "http://www.ibm.com/xmlns/prod/websphere/portal/v6.0/portal-fmt"  prefix= "portal-fmt"  %>    
2. <portal-fmt:user attribute= "cn" />
