为什么Spring JPA不创建数据库（MySQL）表单实体类中的表？
运行应用程序后！！

@Entity
@Table (name = "routess")
public class Routes {

    @Id
    @GeneratedValue (strategy = GenerationType.IDENTITY)
    @Column (name = "id", updatable = false)
    private int id;

    @Column (name = "name", updatable = false)
    private String name;

    @Column (name = "startingpoint", updatable = false)
    private String startingpoint;

    @Column (name = "lastpoint", updatable = false)
    private String lastpoint;

    @Column (name = "date", updatable = false)
    private double date;

    @Column (name = "distance", updatable = false)
    private double distance;

    @Column (name = "numberofmembers", updatable = false)
    private int numberofmembers;

    public Routes () {}

属性、依赖性都不错！
