Hier ist meine objets:Stackoverflow mit Spring Data JPA FindOne
Schritt (4 Klassen)
@Entity
@Table(name = "step")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@Data
public abstract class AbstractStep implements Serializable {
@EmbeddedId
private StepKey key;
@Column
private String htmlContent;
@Column
private Boolean passed;
}
@Builder
@Getter
@Setter
@EqualsAndHashCode
@Embeddable
public class StepKey implements Serializable {
@Column
private Integer numberStep;
@ManyToOne
private TestableEquipment equipment;
}
@Entity
@Table(name = "esthetic_step")
@Data
@EqualsAndHashCode(callSuper = false)
public class EstheticStep extends AbstractStep {
@Column
@Enumerated(EnumType.STRING)
private EstheticState selectedEstheticState;
}
@Entity
@Table(name = "functional_step")
@Data
@EqualsAndHashCode(callSuper = false)
public class FunctionalStep extends AbstractStep {
@Column
private String labelBreakdown;
}
Ausstattung:
@Entity
@Table(name = "testable_equipment")
@Getter
@Setter
@EqualsAndHashCode
public class TestableEquipment implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@OneToMany(mappedBy = "key.equipment", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<AbstractStep> steps = new ArrayList<>();
}
Es gibt mehrere Felder in diesen Klassen in Wirklichkeit aber ich vereinfacht, um besser lesbar zu sein.
Mein Problem ist, dass ich ein Gerät mit 3 Schritten erstellen:
equipment = Equipment
.builder()
.id(1L)
.build();
List<AbstractStep> equipmentSteps = new ArrayList<>();
fs1 = new FunctionalStep();
fs1.setHtmlContent("htmlContent1");
fs1.setKey(new StepKey(1, equipment));
fs1.setLabelBreakdown("breakdown1");
fs1.setPassed(null);
fs2 = new FunctionalStep();
fs2.setHtmlContent("htmlContent2");
fs2.setKey(new StepKey(2, equipment));
fs2.setLabelBreakdown("breakdown2");
fs2.setPassed(null);
fs3 = new FunctionalStep();
fs3.setHtmlContent("htmlContent3");
fs3.setKey(new StepKey(3, equipment));
fs3.setLabelBreakdown("breakdown3");
fs3.setPassed(null);
equipmentSteps.add(fs1);
equipmentSteps.add(fs2);
equipmentSteps.add(fs3);
equipment.setSteps(equipmentSteps);
equipmentRepository.saveAndFlush(equipment);
Wenn ich anrufen versuchen: equipmentRepository.findOne (1 l);
Hibernate-Schleife in der gleichen Auswahl und eine StackOverflowException ist werfen.
Ich verstehe nicht, weil ich eine bidirektionale Verbindung mache.
Jemand hat eine Idee?
EDIT
Verfahren FindOne() wird in einem Test genannt
@Test(expected = ServiceEquipmentException.class)
public void beginTestTestWithEstheticStepNotDefined() throws ServiceEquipmentException {
Equipment equipment = equipmentRepository.findOne(1L);
System.err.println(equipment);
}

Können Sie Ihren Code, der 'findOne' Aufruf und auch die Ausnahme Stacktrace haben. – Swapnil
Ich habe den Beitrag mit der in meinem Test aufgerufenen Methode und der Ablaufverfolgung bearbeitet. – BlaCkOmN
FWIW Die JPA API hat keine solche Methode 'findOne'. Das ist Spring Data JPA ...! = JPA API –
