Examples with ManyToOne jakarta.persistence.ManyToOne used on opensource projects

Example 1 with ManyToOne

use of jakarta.persistence.ManyToOne in project hibernate-orm by hibernate.

the class AnnotationBinder method bindManyToOne.

private static void bindManyToOne(PropertyHolder propertyHolder, PropertyData inferredData, boolean isIdentifierMapper, boolean inSecondPass, MetadataBuildingContext context, XProperty property, AnnotatedJoinColumn[] joinColumns, PropertyBinder propertyBinder, boolean forcePersist) {
    ManyToOne ann = property.getAnnotation(ManyToOne.class);
    // check validity
    if (property.isAnnotationPresent(Column.class) || property.isAnnotationPresent(Columns.class)) {
        throw new AnnotationException("@Column(s) not allowed on a @ManyToOne property: " + BinderHelper.getPath(propertyHolder, inferredData));
    }
    Cascade hibernateCascade = property.getAnnotation(Cascade.class);
    NotFound notFound = property.getAnnotation(NotFound.class);
    boolean ignoreNotFound = notFound != null && notFound.action() == NotFoundAction.IGNORE;
    matchIgnoreNotFoundWithFetchType(propertyHolder.getEntityName(), property.getName(), ignoreNotFound, ann.fetch());
    OnDelete onDeleteAnn = property.getAnnotation(OnDelete.class);
    JoinTable assocTable = propertyHolder.getJoinTable(property);
    if (assocTable != null) {
        Join join = propertyHolder.addJoin(assocTable, false);
        for (AnnotatedJoinColumn joinColumn : joinColumns) {
            joinColumn.setExplicitTableName(join.getTable().getName());
        }
    }
    // MapsId means the columns belong to the pk;
    // A @MapsId association (obviously) must be non-null when the entity is first persisted.
    // If a @MapsId association is not mapped with @NotFound(IGNORE), then the association
    // is mandatory (even if the association has optional=true).
    // If a @MapsId association has optional=true and is mapped with @NotFound(IGNORE) then
    // the association is optional.
    final boolean mandatory = !ann.optional() || property.isAnnotationPresent(Id.class) || property.isAnnotationPresent(MapsId.class) && !ignoreNotFound;
    bindManyToOne(getCascadeStrategy(ann.cascade(), hibernateCascade, false, forcePersist), joinColumns, !mandatory, ignoreNotFound, onDeleteAnn != null && OnDeleteAction.CASCADE == onDeleteAnn.action(), ToOneBinder.getTargetEntity(inferredData, context), propertyHolder, inferredData, false, isIdentifierMapper, inSecondPass, propertyBinder, context);
}

Example 2 with ManyToOne

use of jakarta.persistence.ManyToOne in project hibernate-orm by hibernate.

        AnnotationDescriptor ad = new AnnotationDescriptor(annotationType);
        addTargetClass(element.getTargetEntity(), ad, "target-entity", defaults);
        getFetchType(ad, element.getFetch());
        getCascades(ad, element.getCascade(), defaults);
        getJoinTable(annotationList, element, defaults);
        buildJoinColumns(annotationList, element.getJoinColumn());
        copyAttribute(ad, "optional", element.isOptional(), false);
        annotationList.add(AnnotationFactory.create(ad));
        getAssociationId(annotationList, element.isId());
        getMapsId(annotationList, element.getMapsId());
        getAccessType(annotationList, element.getAccess());
    }
    afterGetAssociation(annotationType, annotationList, defaults);
}

Example 3 with ManyToOne

use of jakarta.persistence.ManyToOne in project hibernate-orm by hibernate.

@Test
public void testCascadeAll() throws Exception {
    reader = getReader(Entity1.class, "field1", "many-to-one.orm7.xml");
    assertAnnotationPresent(ManyToOne.class);
    ManyToOne relAnno = reader.getAnnotation(ManyToOne.class);
    assertEquals(1, relAnno.cascade().length);
    assertEquals(CascadeType.ALL, relAnno.cascade()[0]);
}

/**
 * Method called to see whether given property indicates it uses lazy
 * resolution of reference contained.
 */
protected boolean usesLazyLoading(BeanProperty property) {
    if (property != null) {
        // As per [Issue#36]
        ElementCollection ec = property.getAnnotation(ElementCollection.class);
        if (ec != null) {
