Insert, update row in table have many to one and one to many

[Minh Phuc]

I have 3 entities which mirror from 3 tables in database. The first entity named Khachhang

public class KhachHang implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "IDKH", insertable=false)
private Long idkh;
@Size(max = 250)
@Column(name = "TenKH")
private String tenKH;
@Size(max = 9)
@Column(name = "CMND")
private String cmnd;
@Size(max = 500)
@Column(name = "DiaChi")
private String diaChi;
@Size(max = 50)
@Column(name = "SoDT")
private String soDT;
// @Pattern(regexp="[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?", message="Invalid email")//if the field contains email address consider using this annotation to enforce field validation
@Size(max = 50)
@Column(name = "Email")
private String email;
@Size(max = 50)
@Column(name = "MaDuThuong")
private String maDuThuong;
@Size(max = 250)
@Column(name = "GhiChu")
private String ghiChu;
@Size(max = 250)
@Column(name = "MatKhau")
private String matKhau;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "khachHang")
private List<ThamDu> thamDuList;

The 2nd entity named MaSoThuong:

public class MaSoThuong implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "IDMS", insertable=false)
private Long idms;
@Size(max = 50)
@Column(name = "MaSo")
private String maSo;
@Column(name = "DaKichHoat")
private Boolean daKichHoat;
@Size(max = 250)
@Column(name = "GhiChu")
private String ghiChu;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "maSoThuong")
private List<ThamDu> thamDuList;

The 3rd entity named ThamDu

public class ThamDu implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
protected ThamDuPK thamDuPK;
@Column(name = "NgayKichHoat")
@Temporal(TemporalType.DATE)
private Date ngayKichHoat;
@Size(max = 250)
@Column(name = "GhiChu")
private String ghiChu;
@Column(name = "GiaiThuong")
private Short giaiThuong;
@JoinColumn(name = "IDMS", referencedColumnName = "IDMS", insertable = false, updatable = false)
@ManyToOne(optional = false)
private MaSoThuong maSoThuong;
@JoinColumn(name = "IDKH", referencedColumnName = "IDKH", insertable = false, updatable = false)
@ManyToOne(optional = false)
private KhachHang khachHang;

and the entity are generated automatically

@Embeddable
public class ThamDuPK implements Serializable {
@Basic(optional = false)
@NotNull
@Column(name = "IDKH")
private long idkh;
@Basic(optional = false)
@NotNull
@Column(name = "IDMS")
private long idms;

How can I insert or update table ThamDu?

Moving to the ORM forum.

I don't see any @Entity annotations on them. You can persist and update them using an EntityManager.

There are entities, I don't want post long code. Somebody suggest?

[Bill Gorder]

You asked how to save or update it. I said you save or update entities using an EntityManager which must be configured. Was that your question or are you saying that when persisting or updating the entity you are getting an exception that you neglected to post? If that is the case please TellTheDetails.
