javax.ejb.EJBException : Transaction aborted while inserting record to Derby db table using Entity Manager

Question

嗨，我正在开发 Java EE 7 Web 应用程序，一切正常，但是当我尝试创建与两个实体(即 Car 和 Customer)具有多对一关系的 Order 时，我已经尝试了所有其他发布的答案。请看下面的代码
这是错误日志

这是实体类

@Entity
@Table(name = "CUSTOMER")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "AllCustomer", query = "SELECT c FROM Customer c") 
    , @NamedQuery(name = "findCustomerByName", query = "SELECT c FROM Customer c WHERE c.name = :name")
, @NamedQuery(name="findCustomerById",query= "SELECT c FROM Customer c WHERE c.id = :id")})
public class Customer implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Size(max = 30)
    @Column(name = "NAME")
    private String name; 
    @Size(max = 30)
    @Column(name = "EMAIL")
    private String email;
  
    @Size(max = 30)
    @Column(name = "PHONE")
    private String phone;
    @Size(max = 30)
    @Column(name = "ADDRESS")
    private String address;
    
    @OneToMany
    private List<Order> carorders;

@Entity
@Table(name = "BRANDNEWCAR")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "AllNewCars", query = "SELECT b FROM NewCar b")
    , @NamedQuery(name = "findNewCarByReferencenumber", query = "SELECT b FROM NewCar b WHERE b.referencenumber = :referencenumber")
, @NamedQuery(name="findNewCarById",query= "SELECT c FROM NewCar c WHERE c.id = :id")})
public class NewCar implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Size(max = 30)
    @Column(name = "REFERENCENUMBER")
    private String referencenumber;

    @Column(name = "MAKE")
    private String make;
    @Size(max = 30)
    @Column(name = "MODEL")
    private String model;
    @Size(max = 30)
    @Column(name = "DRIVETYPE")
    private String drivetype;
    @Size(max = 30)
    @Column(name = "BODYCOLOUR")
    private String bodycolour;

    @Size(max = 30)
    @Column(name = "TRANSMISSION")
    private String transmission;
    @Size(max = 30)
    @Column(name = "ENGINE")
    private String engine;
    @Size(max = 30)
    @Column(name = "FUELTYPE")
    private String fueltype;
    @Column(name = "DOORS")
    private Integer doors;
    @Column(name = "SEATS")
    private Integer seats;

    @Column(name = "PRICE")
    private Float price;
    @Column(name = "WARRANTY")
    private Integer warranty;
    @Column(name = "EXTENDEDWARRANTY")
    private Integer extendedwarranty;
    @Size(max = 30)
    @Column(name = "ASSISTANCE")
    private String assistance;

    @Column(name = "StockQty")
    private Integer stockqty;

        
    @OneToMany
    private List<Order> carorders;

@Entity
@Table(name = "Order")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "AllOrders", query = "SELECT c FROM Order c")
    , @NamedQuery(name = "findOrderById", query = "SELECT c FROM Order c WHERE c.id = :id")
    , @NamedQuery(name = "DeleteOrder", query = "DELETE FROM Order c WHERE c.id = :id")})
    public class Order implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    
      @Column(nullable = false)
    protected Float unitPrice; 
    
    @Column(nullable = false)
    @Temporal(TemporalType.TIMESTAMP)
    protected Date timeCreated = new Date();
 
    @Column(name = "Quantity")
    private Integer Qty;
   @ManyToOne(cascade={
        CascadeType.DETACH, CascadeType.MERGE, CascadeType.REFRESH})
    @JoinColumn(name="CUSTOMERID", referencedColumnName = "ID")
    private Customer customer;
    
    @ManyToOne
    @JoinColumn(name="CARID", referencedColumnName = "ID")
    private NewCar car;

这是在 Java Managed Bean 中用于创建记录的代码

        order.setCustomer(selectedcustomer);
        order.setCar(selectedcar);
        order.unitPrice = selectedcar.getPrice();
        order = orderEJB.CreateNewOrder(order);

这里是 Persistance.xml 的详细信息

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <properties>
      <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
    </properties>
  </persistence-unit>
</persistence>

我不知道为什么它不起作用，提前致谢。

以下是 Derby 的 SQL 中的保留字列表:http://db.apache.org/derby/docs/10.15/ref/rrefkeywords29722.htmlORDER是那些保留字之一。
您可以更改您的应用程序以使用不同的单词而不是 ORDER ?
