Я попытался создать небольшой пример, используя Spring, rest, Hibernate.Чтобы сеанс был открыт для завершения маршалинга, я добавил фильтр org.springframework.orm.hibernate3.support.OpenSessionInViewFilter в web.xml
Теперь, однако, я сильно застрял, чтоможет быть потому, что я довольно новичок в AOP.Я сталкиваюсь с проблемой, что сеанс не открывается, когда отправляется запрос:
20.10.2011 17:26:40 org.apache.catalina.core.StandardWrapperValve invoke
SCHWERWIEGEND: Servlet.service() for servlet mvc-dispatcher threw exception
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)
at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:685)
Я думаю, что это та же проблема, что и описанная в Spring + Hibernate с аннотациями: Нет привязки Hibernate Session книть но я не получаю его на работу.

У вас есть предложение, где я мог бы продолжить поиск?
