代未知列JPA

Question

的，這是我的實體類：

@Entity 
    @Table(name = "EMP_EXPORTATEUR") 
    public class EMPExportateur implements Serializable { 

     private static final long serialVersionUID = -8981044305302155626L; 
     @Id 
     //@Basic(optional = false) 
     //@NotNull 
     @Size(min = 1, max = 19) 
     @Column(name = "EXP_CODE") 
     private String expCode; 
     @Size(max = 255) 
     @Column(name = "EXP_NAME") 
     private String expName; 
     @Embedded 
     private AdresseEmbeddable adresse; 
     @Embedded 
     @AttributeOverrides({ 
      @AttributeOverride(name = "indicatifPays", column = 
        @Column(name = "TELFIX_COUN_COD")), 
      @AttributeOverride(name = "numeroTelephone", column = 
        @Column(name = "TELFIX_NUMBER"))}) 
     private TelEmbeddable telfixe; 
     @Embedded 
     @AttributeOverrides({ 
      @AttributeOverride(name = "indicatifPays", column = 
        @Column(name = "MOBILE_COUN_COD")), 
      @AttributeOverride(name = "numeroTelephone", column = 
        @Column(name = "MOBILE_NUMBER"))}) 
     private TelEmbeddable mobile; 
     @Embedded 
     @AttributeOverrides({ 
      @AttributeOverride(name = "indicatifPays", column = 
        @Column(name = "FAX_COUN_COD")), 
      @AttributeOverride(name = "numeroTelephone", column = 
        @Column(name = "FAX_NUMBER"))}) 
     private TelEmbeddable fax; 
     @Size(max = 15) 
     @Column(name = "EXPORTER_POSTOFFICE_BOX") 
     private String chargerpostofficebox; 
     @Column(name = "PRIORITE_INTEGRATION") 
     private int priority; 
     @OneToMany(mappedBy = "exportateur") 
     private List<EMPCertEmpotage> certificats; 
     @JoinColumn(name = "EXPORTER_COUNTRY", referencedColumnName = "COUNTRYID") 
     @ManyToOne 
     private CorePays exporterCountry; 
     @Size(max = 80) 
     @Column(name = "EXPORTER_CITY") 
     private String exporterCity; 
    //..... 
    } 

表將從實體

但插入時出現此錯誤時

Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-01400: cannot insert NULL into ("WEBAPP"."EMP_EXPORTATEUR"."NUM_CONT") 

我這樣做會產生不知道從哪裏來的列NUM_CONT

在您的工作區中搜索EMP_EXPORTATEUR表名，請確保你沒有在其他任何地方使用它Entity
