/**
*
* A security expression handler that can handle default web security expressions plus the set provided by
* {@link OAuth2SecurityExpressionMethods} using the variable oauth2 to access the methods. For example, the expression
* #oauth2.clientHasRole('ROLE_ADMIN') would invoke {@link OAuth2SecurityExpressionMethods#clientHasRole}.
*
*
* By default the {@link OAuth2ExpressionParser} is used. If this is undesirable one can inject their own
* {@link ExpressionParser} using {@link #setExpressionParser(ExpressionParser)}.
