У меня есть несколько длинных (текстовых) запросов, которые я пытаюсь преобразовать в файл orm.xml для удобства чтения и сопровождения, но получаю исключение для отображения: невозможно прочитать XML.
Вот что у меня есть:

Вот как я вставляю EntityManager в мой DAO
@Repository
public class K12DaoImpl implements K12DaoManager{
@PersistenceContext
private EntityManager em;
@Override
@Transactional(readOnly = true)
public List<AttendanceBreakDown> getAttendanceBreakDownBySchoolAndGP(int school, String gradingPeriod, String gradeLevel) {
Object values[] = new Object[]{new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradingPeriod, gradeLevel,
new Integer(school), gradeLevel
};
Query query = em.createNamedQuery("attendanceDetailsBySchoolAndGradingPeriod");
for (int i = 0; i < values.length; i++) {
query.setParameter(i, values[i]);
}
List<AttendanceBreakDown> list = query.getResultList();
return list;
}
}
Когда я делаю mvn clean tomcat: запускаю Я получаю InvalidMappingException: Невозможно прочитать XML Похоже, что orm.xml нигде не найдено поскольку я не могу видеть, где ошибка отображения.
Ранее я успешно выводил запросы с использованием Hibernate, имея файлы hbm, которые сопоставляют запросы с объектами, и эти файлы hbm упоминаются в hibernate.cfg.xml, но теперь я хочу использовать JPA 2.0 напрямую, используя EntityManager.
