別のクラス:

import org.hibernate.annotations.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
@Entity
@Table(name = "DIAS_USUARIO_TIMESHEET")
public class DiasUsuarioTimeSheet {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID_DIAS_USUARIO_TIMESHEET",unique = true,nullable = false)
private Long id;
@Column(name = "DIAS_ID_DIAS", unique = true, nullable = false)
private Dias dia;
@ManyToOne
@Cascade({CascadeType.MERGE, CascadeType.SAVE_UPDATE})
@Column(name = "USUARIO_ID_USUARIO", unique = true, nullable = false)
private Usuario usuario;
@Column(name = "TIME_SHEET_ID_TIME_SHEET", unique = true, nullable = false)
private TimeSheet timeSheet;
public DiasUsuarioTimeSheet() {
}
エラーがあります:
@OneToMany(mappedBy = "usuario",fetch = FetchType.LAZY)
@Cascade({CascadeType.ALL})
@Fetch(value = FetchMode.SELECT)
private Set<DiasUsuarioTimeSheet> diasUsuarioTimeSheetList;
