You should use Spring Security JSP tags.

First declare the correct taglib:

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>

and then use the following code to display for example the email of the current user.

<sec:authentication property="principal.email" />

You can substitute email for any property of your principal object (username, firstName, etc.).

More information about Spring Security JSP tags can be found in the documentation:
