6.8.8 订单实体

订单实体与客户实体是双向的多对一的关系，与订单明细实体是单向的一对多的关系。它的代码如下所示。

OrderEO实体

@Entity

@Table(name = "tb_order")

public class OrderEO implements java.io.Serializable {

 

         public OrderEO() {}

 

         private Integer id;

 

         /** 订单ID */

         @Id

         @GeneratedValue(strategy = GenerationType.AUTO)

         @Column(name = "id")

         public Integer getId() {

                  return this.id;

         }

 

         public void setId(Integer id) {

                  this.id = id;

         }

 

         private String name;

 

         /** 订单名称 */

         @Column(name = "name")

         public String getName() {

                  return this.name;

         }

 

         public void setName(String name) {

                  this.name = name;

         }

 

         private Date createTime;

 

         /** 订单创建时间 */

         @Temporal(TemporalType.TIMESTAMP)

         @Column(name = "create_time")

         public Date getCreateTime() {

                  return this.createTime;

         }

 

         public void setCreateTime(Date createTime) {

                  this.createTime = createTime;

         }

 

         private CustomerEO customer;

 

         /** 订单所属的客户 */

         @ManyToOne

         @JoinColumn(name = "customer_id")

         public CustomerEO getCustomer() {

                  return customer;

         }

 

         public void setCustomer(CustomerEO customer) {

                  this.customer = customer;

         }

 

         private List<LineItemEO> lineItems = new ArrayList<LineItemEO>();

 

         /** 订单所包含的明细条目 */

         @OneToMany(cascade = { CascadeType.ALL })

         @JoinColumn(name = "order_id")

         public List<LineItemEO> getLineItems() {

                  return lineItems;

         }

 

         public void setLineItems(List<LineItemEO> lineItems) {

                  this.lineItems = lineItems;

         }

 

}
