当我创建hibernate数据库时,Hibernate会识别除一个表之外的所有表。所以,当我尝试在那里保存一些东西时,我得到一个异常,因为该对象不存在。 无法创建的表是ORDER。这是代码:
@Entity
@Table(name = "ORDER")
public class Order implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
@Column(name = "order_id")
private double order_id;
@ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@JoinTable(name = "INORDER", joinColumns = {@JoinColumn(name = "order_id")}, inverseJoinColumns = {
@JoinColumn(name = "item_id")})
private List<Item> items;
@Column(name = "delivered")
private boolean delivered;
@Column(name = "current_date")
private Date current_date;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "user_id")
private Client client;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "address_id")
private Address address;
@Column(name = "order_price")
private float order_price;
public Order() {
}
public Order(Client client, Address address, float order_price, List<Item> items) {
this.client = client;
this.address = address;
this.order_price = order_price;
this.items = items;
current_date = new Date();
delivered = false;
}
public double getOrder_id() {
return order_id;
}
public List<Item> getItems() {
return items;
}
public boolean isDelivered() {
return delivered;
}
public void confirmDelivery() {
delivered = true;
}
public Date getCurrent_date() {
return current_date;
}
public Client getClient() {
return client;
}
public Address getAddress() {
return address;
}
public float getOrder_price() {
return order_price;
}
}
和hibernate.cfg.xml文件:

此外,如果它有用,则错误:
