Отображение спящего режима с помощью двух ключей перед началом работы

Question

Со вчерашнего дня я попытался исправить эту ошибку. Я не знаю, где проблема с отображением db. Проблемы начались, когда я добавил courseSubcaegro

Answer 1

Из вашего stacktrace я читал, что Hibernate не может найти отображение сущности.

<class name="com.pb.coursesejb.model.CourseSubcaegory" table="course_subcaegory" catalog=""> 

Он пропускает "т" в:. Com.pb.coursesejb.model.CourseSubca т egory»
Это, так как ваш класс сущности является: CourseSubcategory

Чтобы проверить:. Ли ваш Стол имеет таблицу «course_subcaegory»?
Это также может быть причиной вашей проблемы.

Answer 2

Не уверен, связано ли это с ошибкой. Но, я наблюдаю, что ваше определение отображения имеет атрибут package, указанный атрибут и атрибут class также имеет определение пакета. И они совершенно разные.

<hibernate-mapping package="com.apress.springrecipes.course"> 
    <class name="com.pb.coursesejb.model.Course" table="course" catalog="">
