I'm doing a simple test with hibernate 3 and annotations. Here is the code and configuration I have. I get no exception, but a log entry saying that no persistent class has been found.
Any idea? Thanks in advance!
Hibernate version:
Hibernate 3.1.1
Annotations 3.1 beta 8
Mapping documents:
@Entity
@Table(name="table1")
public class PersistentTable1 {
private int id;
private String text;
private Set table2s;
public PersistentTable1() {
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
@OneToMany
@JoinColumn(name="table1_id")
public Set getTable2s() {
return table2s;
}
public void setTable2s(Set table2s) {
this.table2s = table2s;
}
}
@Entity
@Table(name="table2")
public class PersistentTable2 {
private int id;
private String description;
private PersistentTable1 table1;
public PersistentTable2() {
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
@ManyToOne(cascade= {CascadeType.ALL} )
@org.hibernate.annotations.Cascade (value=org.hibernate.annotations. CascadeType.DELETE_ORPHAN)
@JoinColumn(name="table1_id")
public PersistentTable1 getTable1() {
return table1;
}
public void setTable1(PersistentTable1 table1) {
this.table1 = table1;
}
/**
* @see java.lang.Object#equals(Object)
*/
public boolean equals(Object object) {
if (!(object instanceof PersistentTable2)) {
return false;
}
PersistentTable2 rhs = (PersistentTable2) object;
return new EqualsBuilder().appendSuper(super.equals(object)).append(this.table1, rhs.table1)
.append(this.description, rhs.description).append(this.id, rhs.id).isEquals();
}
/**
* @see java.lang.Object#hashCode()
*/
public int hashCode() {
return new HashCodeBuilder(-20366931, -259946085).appendSuper(super.hashCode()).append(
this.table1).append(this.description).append(this.id).toHashCode();
}
}
Code between sessionFactory.openSession() and session.close():
public class Main {
public static void main(String[] args) {
Session session = HibernateUtil.getSession();
Query query = session.createQuery("from mapped.PersistentTable1");
List<PersistentTable1> table1s = (List<PersistentTable1>)query.list();
}
}
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
}
catch (Throwable t) {
throw new ExceptionInInitializerError(t);
}
}
public static Session getSession() throws HibernateException {
return sessionFactory.openSession();
}
}
