hi,

  @SessionAttributes(Login.SEEEION_STRING)

when using like this if Login.SEEEION_STRING is not in session this will make an exception

org.springframework.web.HttpSessionRequiredException: Session attribute 'user_info' required - not found in session
	org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter$ArgumentsResolver.resolveArguments(AnnotationMethodHandlerAdapter.java:563)
