[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3824) OneToOne join by Non-primary key column throws PropertyAccessException when join column is String
[

]
Sharath Reddy commented on HHH-3824:
------------------------------------
The Item class can be further simplified:
@Entity
class Item {
@Id
@GeneratedValue
Long id;
@OneToOne(optional=true)
@JoinColumn(name = "sku", referencedColumnName = "sku")
Inventory inventory;
}
public void testOneToOneJoinByNonprimaryKeyColumn() {
Session s = openSession(new JoinCounter(1));
Transaction tx = s.beginTransaction();
Inventory inventory = new Inventory();
inventory.quantity = 1000L;
inventory.sku = "SKU";
Item item = new Item();
item.inventory = inventory;
s.persist(inventory );
s.persist(item);
s.flush();
s.clear();
item = ( Item ) s.get( Item.class, item.id );
assertNotNull( item );
assertNotNull( item.inventory );
assertEquals( "SKU", item.inventory.sku );
s.flush();
s.clear();
tx.rollback();
s.close();
}
The test method now becomes:
OneToOne join by Non-primary key column throws
PropertyAccessException when join column is String

Key: HHH-3824
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3824
Project: Hibernate Core
Issue Type: Bug
Components: query-criteria, query-hql
Affects Versions: 3.3.1
Environment: Microsoft SQL server 2005, Hibernate 3.3.1
Reporter: sathish
Attachments: hibernate-3.5.0-beta-3-annotations.patch,
hibernate-3.5.0-beta-3-core.patch, trace.txt
When i try to join 2 entities by OneToOne using a Non-primary key column, it throws the
following exception:
org.hibernate.PropertyAccessException: could not get a field value by reflection getter
of com.xxx.domain.Inventory.sku
Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field
com.inwk.estore.server.domain.Inventory.sku to java.lang.Integer
[Full stacktrace attached]
sku is the Non-primary key String join column by which im trying to do a OneToOne join
between Item and Inventory entity.
Apparently its trying to interpret Sku as an Integer column. Adding columnDefinition as
VARCHAR/String doesn't help either
Mappings for Item and Inventory are below:
class Item{
@Id
Long id;
@Column
String sku;
//some more properties
@OneToOne(optional = true)
@JoinColumn(name = "sku", referencedColumnName = "sku", insertable =
false, updatable = false)
Inventory inventory;
}
class Inventory{
@Id
Long id
@Column
String sku
@Column
Long quantity;
}
