Answer 1

You can use below code to find out principal (user email who logged in)

  org.opensaml.saml2.core.impl.NameIDImpl principal =  
  (NameIDImpl) SecurityContextHolder.getContext().getAuthentication().getPrincipal();

  String email = principal.getValue();

This code is written on top of SAML.
