Приложение FUSE hibernate выдает Сеанс не найден для текущего исключения потока

Я работаю над простой демонстрацией Hibernate на сервере FUSE, и я нашел этот пример кода в этом месте на github. Я пытаюсь запустить этот код в FUSE 6.3 с интеграцией Hibernate 4. Мне удалось установить все необходимые зависимости, но при попытке выполнить операцию с базой данных я получаю следующую ошибку.

Это структура проекта, которая у меня есть.

введите описание изображения здесь

Кто-нибудь сталкивался с такой проблемой при интеграции FUSE в спящий режим. Я смог установить проект без каких-либо проблем. Но когда я пытаюсь выполнить операцию с базой данных, я получаю эту ошибку.

Пожалуйста, может какой-нибудь эксперт поможет мне решить эту проблему.

Решение

Вы можете решить это, изменив следующие вещи.

Добавьте следующее в schemaLocation в теге beans согласно следующему посту.

http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd  

Там вы должны добавить следующие строки. Основано на следующем посте.

<tx:annotation-driven/>
<context:annotation-config />
<context:component-scan base-package="com.vcc.poc"></context:component-scan>

Затем добавьте аннотацию @Transactional для методов, например

    @Transactional
    public Student getStudent(int id)

Измененная аннотация бобов должна быть похожа на ниже.
