Question

My Hibernate annotations work when my application is running on the server, but when I try to test my Hibernate classes with JUnit I get the following error:

org.hibernate.MappingException: Unable to find column with logical name base_batch_id in table T_BASE_EXT

I believe this has something to do with the @Index annotation at BaseExt class. My annotated classess are working and can’t change them, but is there something that I can do to my Hibernate configuration in the JUnit test to get this working?

I’ve found a ticket that had a similar issue: https://hibernate.onjira.com/browse/ANN-207

Here is a JUnit test to replicate this error:

Abstract base class:

@MappedSuperclass
public abstract class Base implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @SequenceGenerator(name = "SEQ_GEN", sequenceName = "SEQ", initialValue = 1)
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "SEQ_GEN")
    private Long id;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
}

Class that extends the abstract class:

And it also has a ManyToOne relationship to BaseBatch-class

@Entity
@Table(name = "T_BASE_EXT")
@org.hibernate.annotations.Table(appliesTo = "T_BASE_EXT", indexes = {
        @Index(name = "IDX_CDA_1", columnNames = {"BASE_BATCH_ID"})
})
public class BaseExt extends Base implements java.io.Serializable {
    private static final long serialVersionUID = 1L;

    @ManyToOne(optional = false, fetch = FetchType.LAZY)
    @ForeignKey(name = "CDA_BASE_BATCH_FK")
    private BaseBatch baseBatch;

    public BaseBatch getBaseBatch() {
        return baseBatch;
    }

    public void setBaseBatch(BaseBatch baseBatch) {
        this.baseBatch = baseBatch;
    }

}

BaseBatch:

@Entity
@Table(name = "T_BASE_BATCH")
public class BaseBatch extends Base implements java.io.Serializable {
    private static final long serialVersionUID = 1L;

}

The JUnit test:

public class BaseTest extends TestCase {
    private SessionFactory sessionFactory = null;

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        final String driverClass = "org.hsqldb.jdbcDriver";
        try {
            Class.forName(driverClass);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

        Configuration cfg = new Configuration()
        .setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect")
        .setProperty("hibernate.connection.driver_class", driverClass)
        .setProperty("hibernate.connection.url", "jdbc:hsqldb:mem:basetest")
        .setProperty("hibernate.hbm2ddl.auto", "create");

        cfg.addAnnotatedClass(Base.class);
        cfg.addAnnotatedClass(BaseExt.class);
        cfg.addAnnotatedClass(BaseBatch.class);

        sessionFactory = cfg.buildSessionFactory();
    }

    @Override
    protected void tearDown() throws Exception {
        super.tearDown();
        sessionFactory.close();
    }

    public void testBase() {
        sessionFactory.openSession();
        assertTrue(true);
    }
}

I’m using Hibernate Annotations 3.2.0.Final and Hibernate 3.6.9.Final

Answer 1

Add this annotation on

@AttributeOverride(name="id", column=@Column(name="base_batch_id"))
private BaseBatch baseBatch;
