Question

为什么休眠不创建表？是真的吗由于Scala，因为我从来没有遇到过Java这样的问题？（用户名和密码被隐藏）

Queue.scala

package model.entity
import javax.persistence._
import org.hibernate.annotations.GenericGenerator
@Entity
@Table(schema = "queuebot", name = "queue")
class Queue {
  def this(id: Int) = {
    this()
    queueId = id
  }
  @Id
  @GenericGenerator(name = "gen", strategy = "increment")
  @GeneratedValue(generator = "gen")
  @Column(name = "queueId", unique = true)
  var queueId: Int = _
  @Column(name = "queueName")
  var queueName: String = _
}

hibernate.cfg.xml

        <mapping class="model.entity.Queue" />
    </session-factory>
