How to get Current logged in user and the roles assigned to the user.

Hi Reader,

This blog gives us the steps you need to perform to get the current logged in user and the roles assigned to the user.

This is a very common requirement we use in Web Dynpro Java.

Say for example depending on the back-end role assigned to the user should be able to view some specific details and perform specific operation.

Procedure:

Step 1 : Add "com.sap.security.api.sda" in to the dependencies of the WebDynpro Java DC.

Step 2 : Use the following code:

try {   String roleId, uniqueName, displayName = null;   IUser currentUser = WDClientUser.getCurrentUser().getSAPUser(); //Code to get current user   Iterator<String> rolesAssignedToUser = currentUser.getRoles(true);//Code to retrieve all the assigned roles      while (rolesAssignedToUser.hasNext()) {      roleId = rolesAssignedToUser.next();//Code to read the role id      displayName = UMFactory.getRoleFactory().getRole(roleId).getDisplayName();//Code to get the display name      }     } catch (WDUMException e1) {   e1.printStackTrace();   } catch (UMException e) {   e.printStackTrace();   }

Step 3 : Use the following imports for the above code.

import com.sap.security.api.IUser;
import com.sap.security.api.UMException;
import com.sap.security.api.UMFactory;

I just hope this small code helps all. this definitely helped me in my project.

Happy to help

Cheers
