我学习Hibernate和得到这个错误：冬眠一对一的关系2
Hibernate:
insert
into
Profesor

values
(?, ?, ?)

我的课PROFESOR：
@Entity
@Table(name="Profesor")
public class Profesor implements Serializable{
/**
*
*/
private static final long serialVersionUID = 3445708995899379632L;
@Id @GeneratedValue(strategy = GenerationType.AUTO) private int idProfesor;
@Column(name="nombre") private String nombre;
@Column(name="apMaterno") private String apMaterno;
@Column(name="apPaterno") private String apPaterno;
@OneToOne(cascade=CascadeType.ALL) @PrimaryKeyJoinColumn private Direccion direccion;
我的课direccion：
@Entity
@Table(name="Direccion")
public class Direccion implements Serializable{
/**
*
*/
private static final long serialVersionUID = -480043084115314876L;
@Id @GeneratedValue(strategy = GenerationType.AUTO) private int idDireccion;
@Column(name="calle") private String calle;
@Column(name="numero") private String numero;
@Column(name="poblacion") private String pobalcion;
显然每个类有你的getters和setter，我开始休眠，并没有太多的想法会导致这个错误或我失踪注释
更新
数据库MySQL中： 
更新2
try {
Direccion d = new Direccion();
d.setCalle("1");
d.setNumero("1");
d.setPobalcion("1");
Profesor p = new Profesor();
p.setNombre("Victor");
p.setApMaterno("as");
p.setApPaterno("as");
p.setIdDireccion(d);
Session session=sessionFactory.openSession();
session.beginTransaction();
session.save(p);
session.getTransaction().commit();
session.close();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
你使用MySQL吗？你是外键吗？我永远不会使用'@ PrimaryKeyJoinColumn'，所以我建议试试这个：'@OneToOne @JoinColumn（name =“idDireccion”，unique = true，nullable = false，updatable = false private Direccion direccion;' – Athanor
是的，我使用mysql和我只是更新我的代码与你的建议，并仍然有同样的问题 – vrvictor
如果Profesor不能有Direccion对象，那么你可以尝试JoinColumn注解。@JoinColumn（name =“DIRECCION_ID”，nullable = true） – mstzn
