Question

我正在尝试从Hibernate生成MySQL表。我的实体之间有一对一的关系。这是代码： -

BuyerPartyDetails类： -

@Entity
@Table(name = "buyerPartyDetails")
public class BuyerPartyDetails {
    /**
     * For annotation all subsequent properties name must be presented as same as in XML file.
     */

    // for buyerPartyDetails table primary key
    int buyerPartyDetailsId;

    // Xml node and buyerPartyDetails.BuyerOrganisationName column
    @XmlElement
    private String BuyerOrganisationName;

    // Xml node and buyerPartyDetails.BuyerPartyIdentifier column
    //@XmlElement
    @Transient
    private String BuyerPartyIdentifier;
    // it is for database column name. Otherwise it conflicts with xml annotation
    private String buyid;

    @Column(name = "buyerPartyIdentifier")
    public String getBuyid() {
        return buyid;
    }

    public void setBuyid(String buyid) {
        this.buyid = buyid;
    }


    // Xml node and buyerPostalAddressDetails table
    // Set provides annotation for xml parser.
    // Get provides annotation for Database framework (Entity).
    private BuyerPostalAddressDetails buyerPostalAddressDetails;


    // Xml node and invoiceDetails table
    private Set<InvoiceDetails> invoiceDetails = new HashSet<InvoiceDetails>(0);
    // must annotate in getter method for database
    @OneToMany(fetch = FetchType.LAZY, mappedBy = "buyerPartyDetails")
    public Set<InvoiceDetails> getInvoiceDetails() {
        return invoiceDetails;
    }

    @XmlElements({ @XmlElement(name = "buyerPostalAddressDetails", type = BuyerPartyDetails.class),
            @XmlElement(name = "buyerPostalAddressDetails", type = BuyerPartyDetails.class) })
    public void setInvoiceDetails(Set<InvoiceDetails> invoiceDetails) {
        this.invoiceDetails = invoiceDetails;
    }

    //@Column(name = "XmlFileName")
    String xmlFileName;


    @Column(name = "XmlFileName")
    public String getXmlFileName() {
        return xmlFileName;
    }

    public void setXmlFileName(String xmlFileName) {
        this.xmlFileName = xmlFileName;
    }

    /**
     * All properties setter and getter
     */

    // must annotate in getter method for database
    // buyerPartyDetails.BuyerPartyDetails_id table column.
    @Id
    @GeneratedValue(strategy = IDENTITY)
    @Column(name = "buyerPartyDetails_id", unique = true, nullable = false)
    public int getBuyerPartyDetails_id() {
        return buyerPartyDetailsId;
    }


    public void setBuyerPartyDetails_id(int buyerPartyDetails_id) {
        buyerPartyDetailsId = buyerPartyDetails_id;
    }

    // must annotate in getter method for database
    // buyerPartyDetails table has one to one relation with buyerPostalAddressDetails table
    @OneToOne(fetch = FetchType.LAZY, mappedBy = "buyerPartyDetails", cascade = CascadeType.ALL)
    public BuyerPostalAddressDetails getBuyerPostalAddressDetails() {
        return buyerPostalAddressDetails;
    }

    @XmlElements({ @XmlElement(name = "BuyerPostalAddressDetails", type = BuyerPostalAddressDetails.class),
            @XmlElement(name = "BuyerPartyDetails", type = BuyerPartyDetails.class) })
    public void setBuyerPostalAddressDetails(
            BuyerPostalAddressDetails buyerPostalAddressDetails) {
        this.buyerPostalAddressDetails = buyerPostalAddressDetails;
    }

    // must annotate in getter method for database
    // buyerPartyDetails.BuyerOrganisationName column
    @Column(name = "buyerOrganisationName")
    public String getBuyerOrganisationName ()
    {
        return BuyerOrganisationName;
    }

    public void setBuyerOrganisationName (String BuyerOrganisationName)
    {
        this.BuyerOrganisationName = BuyerOrganisationName;
    }

    // must annotate in getter method for database
    // buyerPartyDetails.BuyerPartyIdentifier column
    //@Column(name = "BuyerPartyIdentifier")
    @Transient
    public String getBuyerPartyIdentifier ()
    {
        return BuyerPartyIdentifier;
    }

    @Transient
    @XmlElement(name = "BuyerPartyIdentifier")
    public void setBuyerPartyIdentifier (String BuyerPartyIdentifier)
    {
        this.BuyerPartyIdentifier = BuyerPartyIdentifier;
        buyid = BuyerPartyIdentifier;
    }


    @Override
    public String toString() {
        return "BuyerPartyDetails [buyerPostalAddressDetails="
                + buyerPostalAddressDetails + ", BuyerOrganisationName="
                + BuyerOrganisationName + ", BuyerPartyIdentifier="
                + BuyerPartyIdentifier + "]";
    }
}

BuyerPostalAddressDetails： -

@Entity
@Table(name = "buyerPostalAddressDetails")
public class BuyerPostalAddressDetails {

    int buyerPartyDetailsId;

    @XmlElement
    private String BuyerTownName;

    @XmlElement
    private String BuyerPostCodeIdentifier;

    @XmlElement
    private String BuyerStreetName;

    private BuyerPartyDetails buyerPartyDetails;


    // must annotate in getter method for database
    // buyerPostalAddressDetails table has one to one relation with buyerPartyDetails table.
    // buyerPostalAddressDetails.BuyerPartyDetails_id table column.
    @GenericGenerator(name = "generator", strategy = "foreign",
    parameters = @Parameter(name = "property", value = "buyerPartyDetails"))
    @Id
    @GeneratedValue(generator = "generator")
    public int getBuyerPartyDetails_id() {
        return buyerPartyDetailsId;
    }

    public void setBuyerPartyDetails_id(int BuyerPartyDetails_id) {
        BuyerPartyDetails_id = BuyerPartyDetails_id;
    }

    public String getBuyerTownName() {
        return BuyerTownName;
    }

    public void setBuyerTownName(String buyerTownName) {
        BuyerTownName = buyerTownName;
    }

    public String getBuyerPostCodeIdentifier() {
        return BuyerPostCodeIdentifier;
    }

    public void setBuyerPostCodeIdentifier(String buyerPostCodeIdentifier) {
        BuyerPostCodeIdentifier = buyerPostCodeIdentifier;
    }

    public String getBuyerStreetName() {
        return BuyerStreetName;
    }

    public void setBuyerStreetName(String buyerStreetName) {
        BuyerStreetName = buyerStreetName;
    }

    @OneToOne(fetch = FetchType.LAZY)
    @PrimaryKeyJoinColumn
    public BuyerPartyDetails getBuyerPartyDetails() {
        return buyerPartyDetails;
    }

    public void setBuyerPartyDetails(BuyerPartyDetails buyerPartyDetails) {
        this.buyerPartyDetails = buyerPartyDetails;
    }

}

当我运行代码时。我可以看到MySQL表是在数据库中生成的： -

解释表买家派对： -

解释表买家的帖子： -

当我尝试将数据插入表格时，我得到一个例外： -

实例的标识符 com.ma.home.model.BuyerPostalAddressDetails从1更改为0

我的桌子有什么问题以及如何修理它？

用于解析的XML文件： -

这是一个巨大的文件。所以我只从XML文件中共享一个节点： -
