Java OpenJPA级联使用@EmbeddedId保持一对多

java jpa

Java OpenJPA级联使用@EmbeddedId保持一对多,java,jpa,one-to-many,openjpa,Java,Jpa,One To Many,Openjpa,我拥有以下实体：发票 @Entity @Table(name = "invoice") public class Invoice implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "InvoiceID") priva

我拥有以下实体：

发票

@Entity
@Table(name = "invoice")
public class Invoice implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "InvoiceID")
    private Long invoiceID;

    @Basic(optional = false)
    @Column(name = "Date")
    @Temporal(TemporalType.DATE)
    private Date date;

    @OneToMany(cascade = CascadeType.ALL, mappedBy = "invoice")
    private List<Invoiceitem> invoiceitemCollection;

    @JoinColumn(name = "CustomerID", referencedColumnName = "CustomerID")
    @ManyToOne(fetch = FetchType.LAZY,optional = false)
    private Customer customerID;

    // getter/setter
}

InvoiceItemPK

@Embeddable
public class InvoiceitemPK implements Serializable {

    @Column(name = "ItemID" ,nullable=false)
    private long itemID;

    @Column(name = "InvoiceID", nullable=false)
    private long invoiceID;

    // getter/setter
}

这是一个三层独立应用程序，我需要执行以下操作：测试1。对于10张发票中的每一张，添加10张发票项 ....

步骤1，填写发票-发票项目：

for(int i = 0; i < invoiceNumber; i++ ){
 // set invoice where invoiceNumber = 10, 100
        Invoice invoice = new Invoice();
        String formatIn = "dd-MM-yyyy";
        SimpleDateFormat sdfi = new SimpleDateFormat(formatIn);
        java.util.Date inDate = sdfi.parse("29-04-2011");
        java.sql.Date sqlDate = new java.sql.Date(inDate.getTime());

        invoice.setCustomerID(newCust);
        invoice.setDate(sqlDate);
        // set Invoiceitem
        setInvoiceItem(prod, invItemNumber, invoice);

        saveInvoice(invoice);

}

步骤2，发票服务

public String save(Invoice invoice) { InvoiceDAO.log("saving Invoice---> InvoiceItem instance", Level.INFO, null); try { inDAO.beginTransaction(); inDAO.insert(invoice); for (int i = 0; i < invoice.getInvoiceitemCollection().size(); i++) { InvoiceitemPK inItmPK = new InvoiceitemPK(); inItmPK.setItemID(++i); inItmPK.setInvoiceID(invoice.getInvoiceID()); invoice.getInvoiceitemCollection().get(i).setInvoiceitemPK(inItmPK); for (int i = 0; i < invoice.getInvoiceitemCollection().size(); i++) { inDAO.insert(invoice); } inDAO.commitTransaction(); } catch (Exception e) { InvoiceDAO.log("save failed", Level.SEVERE, e); return "Invoice are't saved"; } inDAO.closeEntityManager(); InvoiceDAO.log("save successful", Level.INFO, null); return "Invoice successfuly saved"; }

公共字符串保存（发票）{ log（“保存发票-->InvoiceItem实例”，Level.INFO，空）；试一试{ inDAO.beginTransaction（）；插入（发票）；对于（int i=0；i
