头像实体与联系人实体是双向一对一的关系，它的代码如下所示。

PortraitEO实体

@Entity

@Table(name = "tb_portrait")

public class PortraitEO implements java.io.Serializable {

         public PortraitEO() {}

 

         private Integer id;

 

         /** 头像ID */

         @Id

         @GeneratedValue(strategy = GenerationType.AUTO)

         @Column(name = "id")

         public Integer getId() {

                  return this.id;

         }

 

         public void setId(Integer id) {

                  this.id = id;

         }

 

         private Integer width;

 

         /** 头像图片的宽 */

         @Column(name = "width")

         public Integer getWidth() {

                  return this.width;

         }

 

         public void setWidth(Integer width) {

                  this.width = width;

         }

 

         private Integer height;

 

         /** 头像图片的高 */

         @Column(name = "height")

         public Integer getHeight() {

                  return this.height;

         }

 

         public void setHeight(Integer height) {

                  this.height = height;

         }

 

         private byte[] image;

 

         /** 头像图片的字节数据 */

         @Lob

         @Basic(fetch = FetchType.LAZY)

         @Column(name = "image")

         public byte[] getImage() {

                  return image;

         }

 

         public void setImage(byte[] image) {

                  this.image = image;

         }

 

         private ContactEO contact;

 

         /** 头像所属的联系人 */

         @OneToOne(mappedBy = "portrait")

         public ContactEO getContact() {

                  return contact;

         }

 

         public void setContact(ContactEO contact) {

                  this.contact = contact;

         }

 

}
