Я пытаюсь удалить данные из базы данных, используя javax.persistence.EntityManager. Это класс схема конкретного экстракта моего приложения:Удаление данных из базы данных с помощью EntityManager вызывает нарушение ссылочной целостности
У меня есть класс модели WorkOrder, который содержит Specimen. Я могу создать новые WorkOrder s и Specimen s и добавить их в мою базу данных. Затем автоматически создаются таблицы WORKORDER, SPECIMEN и WORKORDER_SPECIMEN. Код очень прост:
public String newWorkOrder() {
workOrderCurrent = new WorkOrder();
return "new_work_order?faces-redirect=true";
}
public String newSpecimen() {
specimenCurrent = new Specimen();
return "new_specimen?faces-redirect=true";
}
Это способ, которым я упорно WorkOrder и Specimen:
public String saveWorkOrder() {
try {
utx.begin();
workOrderCurrent = em.merge(workOrderCurrent);
em.persist(workOrderCurrent);
workOrdersList.setWrappedData(em.createNamedQuery("SelectWorkOrders").getResultList());
utx.commit();
} catch (NotSupportedException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (RollbackException e) {
e.printStackTrace();
} catch (HeuristicMixedException e) {
e.printStackTrace();
} catch (HeuristicRollbackException e) {
e.printStackTrace();
}
return "work_orders_overview?faces-redirect=true";
}
public String saveSpecimen() {
this.workOrderCurrent.getSpecimens().add(specimenCurrent);
try {
utx.begin();
workOrderCurrent = em.merge(workOrderCurrent);
em.persist(workOrderCurrent);
workOrdersList.setWrappedData(em.createNamedQuery("SelectWorkOrders").getResultList());
utx.commit();
} catch (NotSupportedException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (RollbackException e) {
e.printStackTrace();
} catch (HeuristicMixedException e) {
e.printStackTrace();
} catch (HeuristicRollbackException e) {
e.printStackTrace();
}
return "specimens_overview?faces-redirect=true";
}
Я также возможность удалить WorkOrder с, даже если они содержат Specimen с. Код:
public String deleteWorkOrder() {
try {
utx.begin();
} catch (NotSupportedException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
workOrderCurrent = workOrdersList.getRowData();
workOrderCurrent = em.merge(workOrderCurrent);
em.remove(workOrderCurrent);
workOrdersList.setWrappedData(em.createNamedQuery("SelectWorkOrders").getResultList());
try {
utx.commit();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (RollbackException e) {
e.printStackTrace();
} catch (HeuristicMixedException e) {
e.printStackTrace();
} catch (HeuristicRollbackException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
return "work_orders_overview?faces-redirect=true";
}
На следующем этапе, я пытаюсь удалить всего Specimen из WorkOrder. Код:
public String deleteSpecimen() {
try {
utx.begin();
} catch (NotSupportedException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
specimenCurrent = specimensList.getRowData();
specimenCurrent = em.merge(specimenCurrent);
em.remove(specimenCurrent);
specimensList.setWrappedData(em.createNamedQuery("SelectSpecimens").getResultList());
try {
utx.commit();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (RollbackException e) {
e.printStackTrace();
} catch (HeuristicMixedException e) {
e.printStackTrace();
} catch (HeuristicRollbackException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
return "specimens_overview?faces-redirect=true";
}
При вызове метода deleteSpecimen(), я получаю следующее сообщение об ошибке:

У вас есть ограничение по иностранному ключу - другая запись (и) зависит от этой записи –
Почему сливаются, а затем сохраняются ?! без разницы. –
В моем классе «Specimen» содержатся ссылки на другие классы. Например, «Материал» - это не 'String', а собственный класс. Я удалил его на диаграмме классов, чтобы описать проблему как можно проще. Может ли это вызвать проблему? Я добавил '@OneToOne (cascade = CascadeType.ALL, orphanRemoval = true)' '' Material', но это не решает проблему. – John
