Ich habe einige lange Abfragen (textbezogen), die ich versuche, in eine ORM.xml -Datei für Lesbarkeit und Wartbarkeit zu externalisieren, aber ich bekomme immer wieder eine Mapping -Ausnahme: XML kann nicht gelesen werden.Das habe ich:

So ich Injizieren Sie den EntityManager in meinen 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;
}
}
Wenn ich a mache MVN Clean Tomcat: Lauf Ich bekomme eine InvalidMappingException: XML kann nicht gelesen werden Es scheint, als würde es das nicht finden oder m.xml Überall, da ich nicht sehen kann, wo sich der Zuordnungsfehler befindet.
Ich habe erfolgreich abfragen, indem ich Hibernate mit HBM -Dateien mit Abfragen an Objekte zubereitet und die HBM -Dateien auf Hibernate.cfg.xml referenzieren lassen, aber jetzt möchte ich JPA 2.0 direkt mit EntityManager verwenden.
