Sola opened SPR-14206 and commented

HttpSessionRequiredException should have a getter for 'missing session attribute',It can bring more convince to exception handling.

ideal code snippet:

@ExceptionHandler(HttpSessionRequiredException.class)
ResponseEntity<Error> unauthorizedException(HttpSessionRequiredException e) {
	if(e.getAttributeName().equals("username")){
		//do something else,
	}
	return //something
}

Good idea! I've added a corresponding getExpectedAttribute() method, populated when the exception comes out of our ModelFactory (where we are looking for a specific attribute).
