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

Example 11 with ManyToOne

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

the class Ejb3XmlManyToOneTest method testNoJoins.

@Test
public void testNoJoins() throws Exception {
    reader = getReader(Entity1.class, "field1", "many-to-one.orm1.xml");
    assertAnnotationPresent(ManyToOne.class);
    assertAnnotationNotPresent(JoinColumn.class);

    ManyToOne relAnno = reader.getAnnotation(ManyToOne.class);
    assertEquals(0, relAnno.cascade().length);
    assertEquals(FetchType.EAGER, relAnno.fetch());
    assertTrue(relAnno.optional());
    assertEquals(void.class, relAnno.targetEntity());
}

Example 12 with ManyToOne

use of jakarta.persistence.ManyToOne in project eclipselink by eclipse-ee4j.

the class AbstractFieldMapping method getMemberType.

@Override

    // One to One
    OneToOne oneToOne = field.getAnnotation(OneToOne.class);
    if (oneToOne != null) {

        if (targetEntity != void.class) {
            return targetEntity;

    }
    // One to Many
    OneToMany oneToMany = field.getAnnotation(OneToMany.class);
    if (oneToMany != null) {
        Class<?> targetEntity = oneToMany.targetEntity();

    }
    return field.getType();
}
