我試圖插入到多對多的關係中使用Hibernate，但我得到這個錯誤插入到多對多的關係。錯誤而使用Hibernate

這是我正在嘗試的代碼。 VehicleProduct類
@Entity
@Table(name="m_vehicle_product")
@AssociationOverrides({
@AssociationOverride(name = "pk.vehicle",
joinColumns = @JoinColumn(name = "vehicle_id")),
@AssociationOverride(name = "pk.product",
joinColumns = @JoinColumn(name = "product_id")),
})
public class VehicleProduct extends AbstractEntity{
private String service;
private VehicleProductId pk = new VehicleProductId();
@Column(name = "service")
public String getService() {
return service;
}
public void setService(String service) {
this.service = service;
}
@EmbeddedId
public VehicleProductId getPk() {
return pk;
}
public void setPk(VehicleProductId pk) {
this.pk = pk;
}
@Transient
public Product getProduct(){
return getPk().getProduct();
}
public void setProduct(Product product){
getPk().setProduct(product);
}
@Transient
public Vehicle getVehicle(){
return getPk().getVehicle();
}
public void setVehicle(Vehicle vehicle){
getPk().setVehicle(vehicle);
}
}
VehicleProductId類
@Embeddable
public class VehicleProductId implements java.io.Serializable {
private Vehicle vehicle;
private Product product;
@ManyToOne
public Vehicle getVehicle() {
return vehicle;
}
public void setVehicle(Vehicle vehicle) {
this.vehicle = vehicle;
}
@ManyToOne
public Product getProduct() {
return product;
}
public void setProduct(Product product) {
this.product = product;
}
}
這就是我如何插入。
for(int i=0;i<jobid.length;i++){
product = productService.findByPkey(jobid[i]);
vehicleProduct.setProduct(product);
vehicleProduct.setService(jobdesc[i]);
pkey2 = vehicleProductService.save(vehicleProduct);
}
請指導我。試着從幾個小時來解決這個問題。
編輯
@MappedSuperclass
public class AbstractEntity implements IEntity, Serializable{
private static final long serialVersionUID = 1L;
private Long pkey;
private Boolean deleted;
private String creator;
private Date created;
private String changer;
private Date changed;
private Long version;
@Id
@GeneratedValue
@Column(name="pkey")
public Long getPkey() {
return pkey;
}
public void setPkey(Long pkey) {
this.pkey = pkey;
}
@Column(name="deleted")
@XmlTransient
public Boolean getDeleted() {
return deleted;
}
public void setDeleted(Boolean deleted) {
this.deleted = deleted;
}
@Column(name="creator")
public String getCreator() {
return creator;
}
}........
它包含了所有這些getter和setter方法。
你可以發佈AbstractEntity的代碼嗎？ –
@ Shiraaz.M添加了代碼。 – jellboi
