我有两个实体:
@Entity
@Table(name="team")
public class Team {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(unique = true)
private String name;
}
和第二:
@Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column
private String name;
@Column
private String surname;
@ManyToOne(cascade={},fetch=FetchType.LAZY)
@JoinColumn(name="team_id")
private TeamEntity team;
@Column(name="team_id", insertable=false, updatable=false)
private Long teamId;
}
任何人都可以告诉我如何获得hibernate标准以获得每个团队中拥有多个用户的团队,如何将此查询转换为DetachedCriteria:
select t.*, COUNT(u.id) as usercount from team t LEFT JOIN user u ON t.id = u.team_id GROUP BY t.id ORDER BY usercount, t.name;
