我有一个 PostgreSQL 表和一个表示该表的数据类。我使用注解进行映射，而不是映射 xml 文件。我删除了一些列，因为 db 表和映射类都不需要它们。但我得到一个运行时休眠异常：已删除列上缺少列。这些列在其他任何地方都没有引用，否则编译会失败。现在我将列添加回表（但不是类），它工作正常。有人可以指出方向吗？如果你愿意，我可以发布代码，但 t 只是一个简单的数据类和一个表。

例外：

实体类：

@Entity
@Table(name = "patient_detail")
public class PatientDetail implements Serializable {

    private static final long serialVersionUID = -7765251798211029654L;

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "patient_detail_id_seq")    
@SequenceGenerator(name = " patient_detail_id_seq ", sequenceName = " patient_detail_id_seq ", allocationSize = 1)
    private long id;

    @Column(name = " templateId ")
    private long templateId;

    @Column(name = "description")
    private String description;

    @Column(name = "anatomical_name")
    private String anatomicalName;

@Column(name = "additional_comments")
    private String additionalComments;



    @Column(name = "create_date")
    private Date createDate;

    @Column(name = "modified_date")
    private Date modifiedDate;

        @ManyToOne
        @ForeignKey(name = "fk_patient_id")
    @JoinColumn(name = "patient_id")
    private Patient patient;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @Fetch(FetchMode.SELECT)
    @JoinColumn(name = "patient_id")
    private List<PatientPhase> phases;
.....
getters and setters
