数据表为：
CREATE TABLE orders (

createtime datetime DEFAULT NULL,
...

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

映射文件如下：

@Entity
@Table(name = "orders", schema = "test", catalog = "")
public class OrdersEntity {

private Timestamp createtime;


public OrdersEntity() {    }

public OrdersEntity(int id, String number, Timestamp createtime, String note) {
    this.id = id;
    this.number = number;
    this.createtime =createtime;
    this.note = note;
}

@Column(name = "createtime")
public Timestamp getCreatetime() {
    return createtime;
}

public void setCreatetime(Timestamp createtime) {
    this.createtime = createtime;
}

}

HQL查询：
public void testUser2(){
String hql="select new OrdersEntity(id,number,createtime,note) from OrdersEntity where id=1";
OrdersEntity entity= (OrdersEntity) session.createQuery(hql).uniqueResult();
System.out.println(entity);
}

报错：
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [com.ifox.OrdersEntity]. Expected arguments are: int, java.lang.String, java.util.Date, java.lang.String [select new OrdersEntity(id,number,createtime,note) from com.ifox.OrdersEntity where id=1]

问题：
我的HQL中怎样传这个Timestamp类型的值呀？
