org.hibernate.MappingException:次の型を判別できませんでした:Java.util.Set、テーブル:USERS、列:[org.hibernate.mapping.Column(invoices)]

HibernateがテーブルUSERSでSetのタイプを判別できないという問題があります。 1対多の関係を通じて、テーブルINVOICESの外部キーを作成しようとしています。 1人のユーザーが多数の請求書を生成できます。 My User.Javaを以下に示します。

@Entity
@Table(name="USERS")
public class User {

    @Id
    @Column(name="User_Id",nullable=false)
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer user_id;


    @Column(name="NAME")
    private String name;

    @Column(name="Address")
    private String address;

    @Column(name="Designation")
    private String designation;


    private Set<Invoice> invoices;

    /*@OneToMany
    @JoinColumn(name="Rec_Invoice_ID", nullable=false)
    private Set<RecurringInvoice> recurring_invoices;*/

INVOICE-IDをUSERSテーブルの外部キーとして使用しようとしています。私はここで与えられた指示に従っています Hibernate:Annotation one-to-many(foreign-key)

    @OneToMany
    @JoinColumn(name="INVOICE_ID", nullable=false)
    public Set<Invoice> getInvoices() {
        return invoices;
    }

    public void setInvoices(Set<Invoice> invoices) {
        this.invoices = invoices;
    }

/*   public Set<RecurringInvoice> getRecurring_invoices() {
        return recurring_invoices;
    }

    public void setRecurring_invoices(Set<RecurringInvoice> recurring_invoices) {
        this.recurring_invoices = recurring_invoices;
    }
*/
    // Getters and Setters
    public Integer getUser_id() {
        return user_id;
    }

    public void setUser_id(Integer user_id) {
        this.user_id = user_id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getDesignation() {
        return designation;
    }

    public void setDesignation(String designation) {
        this.designation = designation;
    }

}

My Invoice.Javaを以下に示します。

@Entity

    private Timestamp dueDate;

    @Column(name="deleted")

    private InvoiceItemsDetails invoiceItemsDetails;


    private Client client;

    @OneToOne
    @JoinColumn(name="ID", nullable=false)
    public Client getClient() {

    public void setClient(Client client) {
        this.client = client;
    }

    public Date getDueDate() {

    }

    public void setDueDate(Timestamp dueDate) {
        this.dueDate = dueDate;

    public Integer getInvoice_id() {
        return invoice_id;
    }

    public void setInvoice_id(Integer invoice_id) {
        this.invoice_id = invoice_id;
    }

    public Date getDateCreated() {

    }

    public void setDateCreated(Timestamp dateCreated) {
        this.dateCreated = dateCreated;

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Double getTotalAmount() {
        return totalAmount;
    }

    public void setTotalAmount(Double totalAmount) {
        this.totalAmount = totalAmount;
    }

    public Double getTaxAmount() {
        return taxAmount;
    }

    public void setTaxAmount(Double taxAmount) {

    @OneToOne

    public InvoiceItemsDetails getInvoiceItemsDetails() {
        return invoiceItemsDetails;
    }

    public void setInvoiceItemsDetails(InvoiceItemsDetails invoiceItemsDetails) {
        this.invoiceItemsDetails = invoiceItemsDetails;
    }

私の記憶が正しければ、Hibernateは、フィールド/ゲッターと組み合わせて注釈を組み合わせたり一致させたりすることはできません。 _@Id_注釈がフィールドに設定されている場合、すべてのマッピングはフィールドに従う必要があります。 @OneToMany @JoinColumn(name="INVOICE_ID", nullable=false)getInvoices()から_private Set<Invoice> invoices;_に移動してみてください。このパターンはInvoiceクラスにも適用する必要があります
