这是Hibernate HQL：
public Collection findByForeignKey(Long oidInfoComplementaria) throws DataAccessException {
return getHibernateTemplate().find("from CadInfoComplementaria cadInfoCompl where cadInfoCompl.entidadInfoComplementaria.oid = ?" , new Object[]{oidInfoComplementaria});
}
这些都是实体：
@Entity
@Table(name="PRDTABCADINFOCOMPLEMENTARIA")
public class CadInfoComplementaria implements BaseObject, Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private Long oid;
private EntidadInfoComplementaria entidadInfoComplementaria;
private Date fechaCaducidad;
public CadInfoComplementaria () {
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO, generator="cadInfoComplementariaSequence")
@SequenceGenerator(name="cadInfoComplementariaSequence",sequenceName="SEQ_CADINFOCOMPLEMENTARIA")
@Column(name="OID", unique=true, nullable=false)
public Long getOid() {
return oid;
}
public void setOid(Long oid) {
this.oid = oid;
}
public void setOid(String _tmp){
oid = formatLong(_tmp);
}
private Long formatLong(String _tmp){
if(_tmp == null || _tmp.length() == 0) return null;
return new Long(_tmp);
}
@OneToOne
@JoinColumn(name="OID_INFOCOMPLEMENTARIA")
public EntidadInfoComplementaria getEntidadInfoComplementaria() {
return this.entidadInfoComplementaria;
}
public void setEntidadInfoComplementaria(EntidadInfoComplementaria entidadInfoComplementaria) {
this.entidadInfoComplementaria = entidadInfoComplementaria;
}
@Column(name="FECHA_CADUCIDAD", nullable=false)
public Date getFechaCaducidad() {
return fechaCaducidad;
}
public void setFechaCaducidad(Date fechaCaducidad) {
this.fechaCaducidad = fechaCaducidad;
}
}
@Entity
@Table(name="PRDTABENTIDAD_INFCOMPL")
public class EntidadInfoComplementaria implements BaseObject, Serializable {
private Long oid;
private Long oidEntidad;
private TxtInfoComplementaria txtInfoComplementaria;
private String texto;

@Id

我找不到错误在哪里。 HQL是在一个DAO类中编写的，该类从一个接口扩展而来，该接口也是由一个接口调用的服务类扩展而来的。
有什么想法吗？
非常感谢你的帮助！

问题解决了。我想，问题是Hibernate实体不在hibernate xml配置文件中。
