问题描述
您好，我正在使用Java EE 7 Web应用程序，但一切正常，但是当我尝试创建与两个实体（例如汽车和客户）具有多对一关系的Order时，我尝试了所有其他已发布的答案。请看下面的代码
这是错误日志

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Java托管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>

我不知道为什么它不起作用，谢谢。
解决方法
以下是Derby SQL中的保留字列表：http://db.apache.org/derby/docs/10.15/ref/rrefkeywords29722.html
ORDER是这些保留字之一。
您可以将应用程序更改为使用其他词代替ORDER吗？
