Hibernate没有创建表

Question

我有7个实体，我将hibernate.hbm2ddl.auto设置为crate-drop。当我运行我的Web应用程序时，这句话会打印所有表格

  

create table table_name ....

。 所有表格将创建除一个。 这是我的评论实体，hibernate没有创建它的表。

@Entity(name = "comments")
@Table(name = "COMMENTS")
public class Comments implements Serializable{
    @Id
    @Column(name = "ID",columnDefinition = "NUMBER")
    @SequenceGenerator(name = "COM_SEQ",sequenceName = "COM_SEQ",allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.AUTO,generator = "COM_SEQ")
    private Long id;
    @Column(name = "CONTENT",columnDefinition = "NCLOB")
    private String content;
    @Column(name = "date",columnDefinition = "NVARCHAR2(20)")
    private String date;
    @ManyToOne(cascade = CascadeType.ALL,fetch = FetchType.LAZY)
    @JoinColumn(name = "USER_ID")
    public Person person;

    @ManyToOne(cascade = CascadeType.ALL,fetch = FetchType.LAZY)
    @JoinColumn(name = "DOCTOR_ID")
    public Doctor doctor;

我不明白为什么会这样？
