我想用PostJob检索所有Violation实体，并且不为null。 这是我的违规类：
@Entity
@Table(name="violation")
public class Violation implements Serializable {
/**
*
*/
private static final long serialVersionUID = -5144260292214389455L;
@Id
@GenericGenerator(name = "viol_id", strategy = "com.ivc.talonsystem.util.keygens.ViolationIdGenerator")
@GeneratedValue(generator = "viol_id")
@Column(name = "id")
private Integer id;
@Column(name = "name_empl")
private String nameEmpl;
@NotEmpty
@Column(name = "surname_empl")
private String surnameEmpl;
@Column(name = "lastname_empl")
private String lastnameEmpl;
@NotNull
@Valid
@JoinColumn(name = "id_company", referencedColumnName = "id")
@ManyToOne(optional = false)
private AbstractCompany company;
@JoinColumn(name = "id_post", referencedColumnName = "id")
@ManyToOne(optional = false)
private PostJob post;
@NotNull
@Column(name = "stub_num")
private Integer stubnum;
@NotNull
@Valid
@JoinColumn(name = "id_viol", referencedColumnName = "id")
@ManyToOne(optional = false)
private Violguide violguide;
//getters and setters
}
当我试图使用Hibernate Query来获取对象时：
Session session=createSession();
Query q=session.createQuery("SELECT v FROM Violation v ORDER BY v.dateseize ASC");
List<Violation> violations=(List<Violation>)q.list();
return violations;
我得到完整的Violations列表，其中PostJob为null且不为null。这是hibernate日志：

如何使用Hibernate Criteria API正确完成？ 当我尝试使用Criteria API检索它们时，我只获得了违反Post Post的Violation列表。 这是我的代码，我将使用Criteria API执行此操作：
Session session=createSession(); //createSession method from Parent Dao
criteria=session.createCriteria(Violation.class);
criteria.createCriteria("company", "comp");
criteria.createCriteria("post", "job");
criteria.createCriteria("violguide", "viol_guide"); List<Violation>
violations = criteria.list();
以及我得到的以下日志：
