映射异常：找不到具有逻辑名称的列

Question

我的休眠程序有问题。我已经删除并重写了类，但仍然抛出同样的错误。我没有在这个表中声明 cod_modulo，即使我删除了一对多参数，仍然会抛出同样的错误。我什么都不懂。

这里引用的类。它还具有所有元素的 getter 和 setter 以及空的公共构造函数。

模类

@Entity
@Table(name="modulo")

public class Modulo implements Serializable {

  private static final long serialVersionUID = 1L;

  @Id
  @SequenceGenerator(name = "SEQ_MODULO", sequenceName = "SEQ_MODULO", initialValue = 1, allocationSize = 1)
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_MODULO")
  private int cod_modulo;

  @Column(name = "ancho_modulo")
  private Double ancho_modulo;

  @Column(name = "largo_modulo")
  private Double largo_modulo;

  @Column(name = "alto_modulo")
  private Double alto_modulo;

  @Column(name = "orden")
  private Integer orden;

  @ManyToOne(cascade = CascadeType.DETACH, targetEntity = Lineal.class, fetch = FetchType.EAGER)
  @JoinColumn(name = "cod_lineal", referencedColumnName = "cod_lineal")
  private Lineal lineal;

  //@OrderBy
  @JsonProperty(access = Access.WRITE_ONLY)
  @OneToMany(mappedBy = "modulo", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
  private Set<Balda> baldas;

直系阶级

@Entity
@Table(name="lineal")

public class Lineal implements Serializable{


      /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
      @SequenceGenerator(name = "SEQ_LINEAL", sequenceName = "SEQ_LINEAL", initialValue = 1, allocationSize = 1)
      @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_LINEAL")
      private int cod_lineal;

      @ManyToOne(cascade = CascadeType.DETACH, targetEntity = Seccion.class, fetch = FetchType.EAGER)
      @JoinColumn(name = "cod_seccion", referencedColumnName = "cod_seccion")
      private Seccion seccion;

      @JsonProperty(access = Access.WRITE_ONLY)
      @OneToMany(mappedBy = "lineal", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
      private Set<Modulo> modulos;

      @Column(name = "refrigerado")
      private Boolean refrigerado;

      @Column(name = "horizontal")
      private Boolean horizontal;

      @Column(name = "pos_x")
      private Double pos_x;

      @Column(name = "pos_y")
      private Double pos_y;

错误：

映射异常：无法在 org.hibernate.mapping.Table(lineal) 及其相关的超级表和辅助表中找到逻辑名称为 cod_modulo 的列

尝试为您的 cod_modulo 属性添加 @Column，如下所示：

  @Id
  @SequenceGenerator(name = "SEQ_MODULO", sequenceName = "SEQ_MODULO", initialValue = 1, allocationSize = 1)
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_MODULO")
  @Column(name = "cod_modulo")
  private int cod_modulo;
