Answer 1

Используйте org.hibernate.cfg.Configuration вместо org.hibernate.cfg.AnnotationConfiguration.

Answer 2

В качестве ошибки: Error creating bean with name 'sf' defined in class path resource [resouce/springXML.xml] говорит, что Spring не может создать компонент с именем 'sf', определенным в springXML.xml.

И последующая ошибка:

Could not instantiate bean class [org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cfg/AnnotationConfiguration

говорит, что класс отсутствует. Возможно, вы не добавили требуемую зависимость гибернации или приложение построено неправильно.

Проверьте зависимость и попробуйте перестроить приложение.
