How to lock document by admin Java

Skyor

I have part of code, which runs as system 

AuthenticationUtil.runAsSystem(() -> {...}

and in it i lock document

lockService.lock(nodeRef, LockType.WRITE_LOCK);

 I also tried this code

AuthenticationUtil.runAs(() -> {...}, "admin");

but document locks by current user (user, which authorized in now). I wan't do it by "admin" username. How can i do it?

You can use AuthenticationUtil.pushAuthentication() + AuthenticationUtil.setFullyAuthenticatedUser() + custom code + AuthenticationUtil.popAuthentication() to temporarily switch the entire authenticated user, which should deal with your case. Just make sure you do the push/pop of the authentication context in a try-finally block.
